Title: The most wanted feature?
Post by: Ondra on 2012-09-19, 20:14:25
Since there is so much to implement, I would like to know, what do you want the most.

Everyone has multiple votes, so you cannot simply check everything ;). Choose wisely. I'll use the results as a guideline to what is needed the most.

Caustics are a super useless feature. :) I have never seen them being used in actual production.

They look super sexy on test and promo renders, though. But in real production... they're worthless.

Post by: Ludvik Koutny on 2012-09-20, 10:49:46
Yeah, right, so if you do a packshot of perfume or glass sculpture, then opaque shadow does the trick, eh? So a bit of a correction: For YOU, yourself, personally only you, are caustics useless feature.

Bidir is just a super-necessary feature, because so far, our solution to fireflies is a form of bias (sample intensity clamping) which not a very good solution, and bias it introduces can be in some cases very obvious. Try to render some of your scenes with Max sample intensity value set at 0, and see what happens :-P ;)

Exactly ;))


rawalanche & loocas: I'm agreeing with Loocas on this one - Corona is already fast, so I thought it would be better to add something entirely new instead of speeding it up more. But evidently people want it ;)

Interesting how people use things differently - interactive renders for example, I've tried using fr/iray in activeshade mode, all ok for shader tweaks but to me nothing that a region render can't do. I'd like it, but not as important as the rest. Has anyone had much luck with other render engines and interactivity?
Title: Re: The most wanted feature?
Post by: racoonart on 2012-09-20, 17:16:53
this whole interactive rendering stuff is for tweaking shaders on a sphere and placing lights for reflections on a car... I didn't use it for anything useful. May it be VrayRT or Iray. For me, it's more a toy than a tool. As soon as I have a production scene with tons of textures and millions of polygons this whole IR stuff is unusable anyways... As Paul says: region rendering is good enough.
Title: Re: The most wanted feature?
Post by: Ondra on 2012-09-20, 18:09:24
To clarify, Corona RT would be the exactly same renderer, just launched interactively with optimized parsing when only a part of the scene is changed.

I have no intention of doing second half-assed interactive renderer with half the features. Not now, not ever ;)

Thanks! That's great to hear :) VrayRT is completely useless for anything serious since production render doesn't match the RT stuff... +unsupported materials etc....

You can use VrayRT to render final frames, sure it doesn't support all Vray features, but you can still render final frames from it.

I'm 50/50 with interactive rendering, I agree once the scene hits a certain amount of complexity its useless, but the one thing I like it for is adjusting the Sun, seeing where my shadows land.
Normally Nitrous/viewport is okay for this, but once you start trying shine the sun through trees etc... its no good.
Its also good for rendering cars, changing hdri's, watching the reflections, tweaking car paints.

Distribute rendering is my number 1:
Theres nothing worse than not being able to speed up a render under crunch time, clients breathing down your neck.
Knowing I can add another render node to speed up a high res still is essential for productions work.

cheers

Once you've tried interactive rendering without limitations (such as in the caustic visualizer or arnold), believe me - your workflow will change completely! I would love to see a max-renderer support proper interactive rendering.

Post by: NicolasC on 2012-10-18, 15:49:26
Talking about region rendering, it would be cool to have a region directly in viewport, with slider controlling AA (ala XSI). Maybe is it more a 3dsmax thing though ... I remember there was such a thing for 3dsmax 9 some time ago, but never been updated :(

I would have probably already done that, but I see 3 problems with this:

1) the set of features changes constantly, and I'd have to update it (i would need custom export routines for for example sunlight, skylight, etc., and I'd have to change them every time I add new parameter)

2) Related: there is no reasonable standard file format for scenes

3) there is no reasonable library for doing GUI in C++

Those are the reasons, why there is not currently and for some time wont be a production-ready standalone Corona (there is one CLI based, but that is only for my debugging needs)

It's easier to explain to client that it is going to take a little more time, than to tell them you simply can not do IES, or that you can not do SSS.
Title: Re: The most wanted feature?
Post by: cecofuli on 2013-03-07, 23:22:00
For me, professional studios are Companies from, I don't know, 20 to 50 rendernodes. Make >3 minutes FullHD animation or heavy production like catalogue >4K with 30 or 40 shots. Not a single man in a room with 2 PC to make a nice rendering for Evermotion gallery ;-)  If I have a robust DR I can do strong job. Without no, I can't. I can simulate SSS, or I do fake IES. I cannot simulate DR. But this is my point of with. Anyway, today I read the entire (ALL) forum. I like Corona, very much...
Title: Re: The most wanted feature?
Post by: Ludvik Koutny on 2013-03-07, 23:30:51
People in companies with 20-50 rendernodes are usually smart enough to use backburner or any other network rendering manager to distribute rendering of individual animation frames across all the nodes they have, instead of using less efficient way of rendering each frame on a single computer and transferring pieces of scene back and forth between all the nodes contributing to DR.

Only scenario where DR really shines is rendering of huge resolution complex still images.
Title: Re: The most wanted feature?
Post by: racoonart on 2013-03-08, 00:46:24
I didn't test it with corona (yet) but, for example, deadline is able to render tiles. So you could split up (automatically) a highres rendering to 5x5 tiles and send it to the farm which should be pretty much the same speed than doing it via DR.
Sure, it is a bit more comfy to do it with DR but at the end its still possible to do it this way - and that's why DR is not that important for me atm. I would way more profit from things like light include lists or ies or matteshadow (which can be the killer argument when choosing the right renderer for a production)

From a personal point of view, DR is of most use when I need to turn out a large image fast and in emergencies, otherwise I'll just submit via bb and wait. Having said that there seem to be more and more 'emergencies' from my clients atm ;-)
Title: Re: The most wanted feature?
Post by: MatEvil on 2013-03-15, 11:16:58
I can choose only 3 but I will give my opnion in details, premiere I will say you my experience;

I worked for more years in the Arch-viz sector, in the last 5 years I specialize in the sector of animation and in particular on the world of Fluid Simulation. In production of animation is more important the quality/time for frame and Corona Render (for what I see now) is very good...

SSS -> good idea

Multilayer material -> good idea

Matte/shadow material -> I think is fondamental for one renderer... obviosly for animation sector...

IES lights -> good idea

Carpaint shader -> good idea

Multilight (postprocess light intensity editing) -> good idea (is very great step)

Hair & Fur -> good idea

Distributed rendering - > I need try with Backburner of 3DS Max, I think is a good solution Backburner for animation and DR for still frame.

Also I think, for my point of view, the integration of Particles Systems (Standard and Pflow) usually I render it in another engine, but in some case is very userful render it in the same engine....

Thank you and sorry for my english

Please, add button to save all rendered channels in one file (tiff or psd).
It's very useful feature: it save the time for saving channels, set in order the files in render folder, tiff or psd formats can be viewed in any viewer or windows explorer and all versions of photoshop.
And one more thing: vray can't do this, althought it can save all channels in a group of files. Save in one file with one button is the next step.

EXR can't open in any viewer or old version of photoshop. No thumbs in windows explorer too.
32 bits, gamma options, and other EXR stuff don't need in many cases.
Tiff or PSD is simple and easy not only for us, but for other people who works with us (architects, designers, and futher).
It just an option, for a choose. Not everyone know about EXR and how to work with it.
Saving from buffer with one button to one layered file will be good function for often use, i promise ))))

The thing is, there is a dedicated, free, easy-to-use library for EXR already plugged into corona. Psd and Tiff would require some similar library and the effort to plug it in ;)

how likely is the possibility of the Distributed rendering of a single frame across network?

I really do not understand what is written above they do not see the use case. For me it is clear - 10 nodes will be significantly faster consider any frame regardless of the resolution. Tell me - is technically difficult to implement Distributed rendering?

Title: Re: The most wanted feature?
Post by: quizzy on 2013-06-14, 09:12:52
my 2 cents in order of importance:
1) Matte shadow. Corona delivers such real renders, you just have to be able to implement it into real footage
2) Velocity render element. you know why
3) Distributed rendering.
How are you planning on implementing DR? I really hate the vray way, cause that one has a copy of max running the entire time (ow, and I never managed to get it working). MR version is quite okay, but crashes when one of the nodes crash, leaving you without any image. Updating all the nodes would be great if that could either be with an installer, or even cooler would be that it installs the correct version automatically. Even more cool would be that more versions can be installed at the same time on all the nodes.
Title: Re: The most wanted feature?
Post by: bnzs on 2013-06-14, 09:25:39
I think  Distributed rendering its very very need feature - for me one thing not suitable of corona - is render time - but if I could use over 10+ render nodes (who have same cpu as mine one) as well as I do in vray - it would be great

ah ok just saw that yeah thx will +1 to that :) must say i'm mighty impressed with Corona as it is anything extra is a bonus.

So far the things i keep going back to Vray for are the SSS shader and better control over lights.  focusing lights, a spot light for instance i find quite difficult to achieve in Corona
pointing the rays in the same direction is somewhat tricky and the results haven't for me came out quite that well.  i confess i do need to spend more time on it. but for me those are the things that i would love to see. FOG, SSS and better lighting control

great stuff though :)

I did my masters degree thesis by comparing two rendering softwares from student users' point of view. Those softwares were vray and maxwell, one for biased and the other one biased. Rendering times was not much of a concern but user friendliness and  ease of use was.
The result of the research surprisingly favored maxwell because of easiness of use and time spent on rendering parameters.
What my point is that if corona wants to be popular and accepted by masses, it may include some preset settings for the unexperienced user. Diversification on multiple platforms is another concern, for example , from my observations, arion and octane is losing their development energy by spreading their efforts on multiple platforms.

Problem for not having PFlow support is that I use it for all sorts of things. Not just for making smoke.....
I use it in modeling, adding details, scattering, as well as for making abstract shapes for design work. It is such a versatile tool that spans many workflows for me.

I don't think the Mesher object would cut for me in the long run. And to be fair, Corona sort of needs to come out of the gate and support as much as it can :)

Same here! PFlow is such a powerfull tool for adding all kind of details and effects. Right now I´m using the mesher if possible to get around with. But it gets kind of frustrating, especially when I need to change some settings. On the other hand, Corona is evolving so fast, that it almost does´nt matter, which feature comes first! Looking forward to Alpha 6 :-)

Adding my 2 cents:

I really need the "render to texture" feature enabled. I use it all the time for game development to bake lightmaps e.t.c. I normally use Vray to do this, but have to brute force everything else it's a splotchy mess.

This feature also comes in massively handy for fly-through animations (I'm sure the arch-viz guys here can relate). For example, rather than calculating GI for every frame of the animation, you calculate it once, bake the lighting solution per-object as a texture and then render in scanline / without GI at a speed of seconds per 1080p frame, as opposed to minutes / hours per frame.

This is the last piece of the puzzle that would allow me to fully ditch Vray and purchase a Corona license upon release.
Title: Re: The most wanted feature?
Post by: Fibonacci on 2014-02-22, 19:11:02
Well, this is not really important for everybody, but nice and handy for the texture artists's feature, should be nice in the Corona.

This is something "TextureMap Preview", which make a render of the currently selected texture map from the material editor/slate editor on the objects. The "ShowMap In Viewport" function is really bad, not give good and accurate result. And if it should be working with procedurals, that's goin' to be perfect.  :)

I think Corona needs to be attractive for character stuff. As you can see on the gallery, we have only arch-viz.

Every item is cool, but not every item will give the sense of "complete solution" (Even knowing that complete is something that doesn´t exist). But you know what i mean... So i Agree with cecofuli.

u mean adaptive sampling?
Title: Re: The most wanted feature?
Post by: benjamincillo on 2014-06-12, 18:16:04
Hi kramon

I'm not expert on which acaptive sampling means

but what I suggest is something to help to clarify how much "clear enough" the image is.

I mean, when rendering large images, and you spend 4 or 5 hours, probably you cannot notice how much difference is, as far image stills computing...probably a 4 hrs image can be considered 95.00% clear from noise, and a 5hrs image is 99% and so on...you never kwno when image is clear enough, it basically depends on what you need

of course, having this option may help to know when an image is ready to use as a test for materials, light and so on.

for samples I usually spend 5-10 min for a 720x405 image, but sometimes noise is very noticeable. If I could know image is at least 75%-80% clear from noise, I would know much much my image samples would take, or a proximately time for rendering a large image, instead being returning back to my pc to check how it is.


I attached a WIP project
it takes only 03:54 min to have an idea about materials and light are, but certainly I dont know how much better it would be in 15 or 20 min rendering

sorry if that sounds kinda crazy... :P

ps, sorry for any english mistakes

Yes, something that show info about how much time it will take to clear an image from noise, maybe talking about percentage. this way, someone could stop the render when image is 50% -80% clear from noise.

could it be possible Keymaster?
Title: Re: The most wanted feature?
Post by: racoonart on 2014-06-13, 01:13:12
What you're requesting is simply adaptivity. Technically noise is just the absence of sufficient information - that means a pathtracer would have to collect an infinte number of samples to reach "noise free" images (or in your term "100% clear from noise".
What you want to have is, simplified, a threshold of acceptable value difference (like the dmc noise threshold in vray), which is nothing else than an adaptive approach: "keep sampling the pixel until the noise threshold is reached"

Title: Re: The most wanted feature?
Post by: Juraj on 2014-06-13, 19:22:55
I sort of think he doesn't necessarily ask for adaptivity, he asks about some direct information on "how" clear/noisy the image, as Laci wrote, a clue on passes :- )

I.E, for example,. how Maxwell groups passes into SL groups, and you have a some estimated values, for example 12 (I don't know, I picked that number randomly, I don't use Maxwell), is enough for interiors,etc.
At the moment, image might be completely clear by 100 passes, at for example 32/2 Gi/Light samples or 200 passes if you use 16/2 settings,etc.. and you basically stop either based on eye evaluation, or by
educated estimate based on previously done renders and test.

He just wants some more exact way to estimate this. But I guess the threshold Deadclown write might be that.

thanks for helping to clarify my request guys

Yes, What I suggest is to have a VISIBLE INFO about how much noise or clear the image is, just in order to know WHEN I could stop the image, depending on my needs

if an image still noisy after 10 min, but info on screen says that is 50% "clear" I can wait 10 minutes more for a better one, just ir order to have a clue about redering times.

It would be use for batch rendering, instead asigning xxx hrs, or XXX passes to all images- which in most cases - are exceeding the needs, user can say: "ok for a 720x405 it may take 5 min for have a 99% "finished" render , and for 5000x3000 it would take  2 hours for a 95% clear image (since waiting for last 5% would be probably an excess, and almost a-not-noticeable quality).

what do you think?
Title: Re: The most wanted feature?
Post by: andreholzmeister on 2014-06-24, 03:34:53
Of course isosurfaces is not a priority feature, but it is very interesting and it looks like there is no render out there featuring this natively. My votes goes for SSS, hair shader, and better gi with low flickering for animation, since I am a character animation driven artist.

Yes some. but Acceleration and full implementation are 2 things. Any for the latter out of core fixes memory issues, Octane will have it later this year.

Look at Indigo. They get 2-3x speedups by putting some of the workload on the GPU.

from the main page, in the FAQ (www.corona-renderer.com):
Quote
Is Corona CPU or GPU based?
    It is entirely CPU based with no intention of making a GPU version in the foreseeable future. The reason is that the CPU version is fast enough, and there would not be nearly enough speed improvement to justify the amount of changes required and reduced flexibility.

I am not sure/can't remember who (could be both Keymaster or Vlado or someone else :- D ) said the spectral yielded very little benefit in rare cases during the whole sRGB vs WideGamut RGB discussion/fight.
I completely forgot about this until the latest private Weta renderer started getting hype on net in past days.

Still remember how in school they tried to force us to FryRender with "It's truly photorealistic, it has spectral rays". Was very reminiscent of Idiocracy's "But it got all they need, it got electrolytes".

Would love to know some Keymaster's thought on this. Just out of curiousity.

hi to all.

If u implement something like photoshop layers blend mode (muliply, lighten, overlay, dissolve), directly on coronaframebuffer with percentage like photoshop u will destroy every other render engine, becuase u can correct istantly every channel and elements.

Keymaster : Since you said your doing the sss,multilayer etc can you at the same time do a hair shader? :) It belong to the sss skin shader to  me, we need both to do good character with Corona.. and you can count on me to do test render and nice renders when you come up with these shaders , I just can't wait :))

I would like to see "post production/VFB" multilight integration. Essentially like it's already now for the whole image but specifically for lights independently.
cf Maxwell Multilight : http://support.nextlimit.com/display/maxwelldocs/Multilight

I guess it can't be done through HDCache like Vlado on Vray already stated (with LC) but he said they are working on it through dual brute force.
So even if this can be done through dual PT, it would be great.
Plus, little treat, a little button inside the VFB that could parse the modification done from the multilight straight back to the scene would be the awesome.
That way, one could just start a render, multilight the selections of lights in the VFB, balancing the intensity and the color temps, and send back the modifications to the scene so we can have the final render looking straight good plus being able to render with HDCache.

This would be a killer.

vrayblend mtl please?! does anyone know if the next versions will come with this feature? vray dirt are welcome to! =D
No offense, but this makes me doubt you actually used corona :|
Corona supports maxes own Blendmaterial [100% same as vrayBlendmtl exept coats], if you are looking for coats like from the vray mtl you can do so by daisy chaining blends in the SlateMaterial Editor easily.
What do you want from vray dirt, if its AO, then corona does support that aswell for quite some time now.
There is a CoronaAO texture already there. If you need an AO pass, add corona's "CTexmap" as a render element and apply the CoronaAO texture. Then in Actions press render elements and you will get your AO pass.

Lastly, if you are into optimizing:
Need AO? Duplicate final scene,  delete all glass material objects and render with Mentalray's GPU ambient occlusion. (coronas is kinda quirky still)
Need DOF? Render Z-depth pass, and your image in 32-bit. Just like the real thing only 100x faster.
Need MoBlur? Start spamming Keymaster to implement a velocitiy pass already, or duplicate scene and render a velocity pass in scanline.  Just like the real thing only 100x faster.

He simply means layered materials. Some of the softwares implement simplified version where you can layer only reflective layers. So that's why he refers to it as layered reflections. Corona can do that already, but at the moment only by using blend material, which requires nesting if one needs more than two layers. There will be hopefully multilayer material soon.

Sounds good to me!
Maybe a pipe dream but if HDR Light Studio could be integrated with IR in the same way as it has in Vray for Rhino, that would be gold.
In the Rhino version LightPaint  works directly with the RT viewport, seeing as it has not been done yet in Max with any other renderer I assume it may not be possible.
However when Corona for Rhino is developed it would be a great feature!

As a 3D animation studio, (not focused on architectural visualisations)
we would only consider to switch to an alternative renderer when all the important features for animated character and environment rendering are included.
So we will test Corona once there is at least a good hair shader available.

As a workaround you can still use the 3dsMax built in effects for glow and glare.
(Although I'd rather do that myself in post tbh)
Title: Re: The most wanted feature?
Post by: sebastian___ on 2015-03-18, 13:38:39
A real time glare would be better applied to high brightness objects. Unless you use hdr exr or similar, a post solution would not identify the hot spots as good. The glare intensity in Octane would keep increasing if the hot spots would go beyond the 255 white. Not to mention how it helps you compose the shot better since you see all those glare effects in realtime.
 I'm guessing the Octane solution is so fast because the glare effect is progressive as well. It's not applied instantly in a single frame, but applied progressively over multiple frames, just like clearing the noise over multiple frames.

Notice how it completely changes the picture having the real time glow in the dark scene with the light.

It's still post effect, even in Octane, same thing as Vray Glow. Or ArionFx in PS, even Magic Bullet works similarly. All plugins let you work on 32bit linear unclamped file to extract proper highlights.

But they all look shit compared to Unreal post process tab :- D I don't know how those guys do it, but every feature is miles above everything else.
The tonemapping and post effects look so good and natural straight out of box it makes every rendering engine look like from 1995 :/

I don't see why this gets so ignored and frowned upon (esp. by Vlado). I want to select my output to look for example.... NikonD800 + 1/4f 24mm lens raw file and do post-production from that point. Not some ugly reinhard mess on top of linear file.

Progressive Rendering in Network rendering like Maxwell
(http://support.nextlimit.com/display/maxwelldocs/Progressive+Rendering+Workflow (http://support.nextlimit.com/display/maxwelldocs/Progressive+Rendering+Workflow))

Maxwell can be configured to allow the render servers to render a complete sequence at (n) passes -
For example (6,12,24)

The whole sequence will finish to render each file at 6 passes (at a low Sampling Level) and move to the next frame. When the whole sequence is complete it will then RESUME the render from 6 to 12 (does not need to re-render the already 6 passes) and save each, finally it will render the passes from 12 -24

In this way you can already use the sequence in compositing at a lower quality while the higher quality is in progress

Dispersion is on my wishlist as well, especially for glass closeup shots.
If you are in need for dispersion now, there is the physical workaround:
Render the beauty Pass without Caustics
Render a black and white Pass for with caustics only, which corrensponds to the IOR of the wavelength or Red
Render a black and white Pass for with caustics only, which corrensponds to the IOR of the wavelength or Green
Render a black and white Pass for with caustics only, which corrensponds to the IOR of the wavelength or Blue

Set the Channel Color for these to the corresponding colors. And add them on top in Photoshop for a photo or in a compsitor for Video.

???

Profit with dispersion. Same works for refraction. (although you would have to do it infinitly for all the colors, you can also do with 5 colors, including Yellow and Purple)

No, it's not about wrong materials setup... I think I can setup materials more or less correct, but I have sometimes problems with my clients (I work as architect/interior designer/visualizer), especially with interiors with white walls mostly, because gi color bleed is more visible there.
I always try to explain them, how things in reality works, by showing them photos of similar interiors where color bounce is more pronounced.
I know that cheating gi bleed is physically  incorrect, but in some circumstances it would really help. If there are only 2 or 3 materials, that needs GI Rayswitch adjustment, that's really not such a problem, but when you have 10 or more materials, then that's becoming tiresome, counterproductive and time expensive. Not to mention it's PITA to adjust and make changes to materials.
VRay has this option, and I use it almost on every project, sometimes only a little (color bleed on 85% for example), sometimes more.

I'm attaching a couple of quick test images, where this "problem" is more visible. It's a simple scene, green floor tiles and white walls (diffuse value is 200) whith some minor glossy reflections. At 100% gi color bleed I would really not be able to convince my customer, that the walls are white instead of green. OK 0% looks realy fake, but 30% (or maybe 40-50).. that would be ok.

Adjusting MSI values wouldn't solve this I suppose...

Regards,
Luka

You can create multiple materials using multi/sub and put them inside one rayswitch, or use MultiMap in material ID mode, or render separate GI pass and alter it in post. But I do not think some overall GI color bleed setting will be ever included. I'm not decisive, though. ;)

automatic reduction of albedo on problem materials as shown red in the albedo pass.  with either the option of only lowering the problem areas diffuse value, or lowering all materials by the same value.

improving distributed rendering so the same outcome can be achieved with the same number of passes when using render farms, currently there seems to be a problem with fog materials, reflections, and lighting when using multiple nodes.  I'm using pixelplow at the moment, and scenes with volume materials render with extreme distortion.

Guys, talk with Blender Foundation to find a way to implement Corona into Blender without lack of speed (like as waiting to export scene etc)


Do you all understand how much important for speed is GI calculation method? Irradiance caching will be good option.

Agreed.

Also, I wouldn't want the team to spend any time on material presets. If there's a demand for it some 3rd party will probably pick it up anyways.

I guess (and hope because I´m going to vote it) it´s about having passes not occluded by refractive materials but correctly calculated instead (material ID, AO or any mask from objects behind glass for example). Similarly for reflections.

Good Luck

It would be nice to be able to render in Corona overlapping faces and surfaces with same material without problem and artifacts, same in Vray render exist option /Secondary Rays Bias/
very often used especially in Archiviz projects models imported in 3dmax from different others applications as SketchUp, ArchiCad and etc.
constantly come across such a problem with the model geometry and in Vray this is solved very simply, just need to change this value to 0.02 , for example///
without this Corona can not be a full designed renderer for ArchiViz works///

Please vote for the Disney PBR material. Not convinced? Heres my 2 cents:
4k & 8K PBR scans are coming. DDO / SubstancePainter and independents are churning them out. They come with a bunch of maps. The trend is inevitable, just like the touchscreen on our phones. Now, the maps come with AO, BUMP, DEPTH, GLOSS, HIGH GLOSS, NORMAL and ROUGHNESS. From the get-go you count more maps than you normally plug into Corona right? Here's is a free commercial use example in 4K:
http://real-displacement-textures.com/ (http://real-displacement-textures.com/)

I am sure there is a round-about way to use the maps. But it probably differs from map to map, takes a lot of testing, with huge textures. Not ideal if you use a lot of them. What about METALNESS? Configuring assets in a game-asset-type of production pipeline and taking them into 3ds Max / Cinema 4D in 4K or 8K to use sweet sweet Corona for ArchiViz? Again you can fake it a little but...it's probably painful. The GGX was spot on by the way. But it is kind of the tip of the iceberg so-to-say. And I have no idea about coding but Disney PBR is certainly in top 3 hardest to implement. But it's the thing that also blows the competition out of the water.

So let's just marry the two. 8K PBR scans have a place if Corona implements the insane bat-shit-crazy options of a Disney PBR. And if you don't know what that is, it's a shame to not think it over a bit before voting. Here is where you get started on the many possibilities offered by such material options:

Off Topic: Since I post once every 2 years, I would like to thank the guy who does the tutorials. That guy is simply the best. No other render software offered such an extensive view on how to be used. A million thanks.

This.

How come more people vote for "presets" ? Are they aware they would be worthless since the material doesn't even work as it should. You can't get physically correct specular response without tinkering with IOR and Specular clamping (see Dubcat's guide) when having any glossy other than 1.0.
Having straightforward artist-oriented materials would be biggest boon for 3D beginners, who could then be easily explained the principles in 5 minutes.

I vote for an improvement to the shadow terminator smoothing.  Turbosmoothing doesn't seem like a long term solution. Thanks :)

Yeah, I would vote for that too!

When using Vray rendering same object with bruteforce, the effect is MUCH less than Corona. Isn't rendering with bruteforce in Vray basically rendering physically?

Ive read the https://coronarenderer.freshdesk.com/support/solutions/articles/5000516258 

"This limitation is typical for physically-based renderers not being able to cope with "fakes" such as shading normals."

 Well I'm glad too but what corona's team really means by the "better displacement" one can only guess )) yet still I had put one of my votes there anyway.
To me, for example, it does mean introduction of some sort per material or per modifier or even both of those (which would be most useful imo) displacement quality\precision control.
 Why ? Well, to be able to do some foreground tree bark\ground\walls etc or even some characters or whatever, which could use current automatic per pixel control (as it is imo quite efficient for close to camera\foreground objects already) + some distant mountains\hills etc, which could use some pretty sparse world space unit sample settings\distance + some distant but closer objects with could use either of those with less precise\dense settings than the foreground ones but still would be able to retain rather decent displacement quality even on lower res renderings - well to be able to do all of this in the same scene with a more efficient control over the quality\precision vs ram and processing power usage. Of course, it would be especially useful in larger outdoor scenes but I think some smaller ones could greatly benefit from that too and, well, vray got it and it helped me a lot in the past so why corona shouldn't )).
Title: Re: The most wanted feature?
Post by: peterguthrie on 2016-04-20, 19:42:31
well I hope that 'better displacement' means something similar to vray '2d' displacement because we have always found that much easier to control and better suited to arch viz work

Anything without the pre-calc phase. Takes endless time to adjust when single fullHD frame takes 1-2 minute (using 40 core machine) on the default 1.5px value.

"2D"/Texture-space disp (unnaffected by light), is also great, esp. for micro disp.

Yes. I mean physical shader in 3ds Max 2017. I did a test (with ART, of course) and seems like it worked very good with texture exported from Substance Painter or DDO.
Full glossiness range is very cool, we do not need glossiness remapped anymore. But PBR shader will make Substance Painter - 3ds Max workflow easier.

proper specular dimming.

Every night before I go to bed, I do this crazy ceremony dance around my bed while pray to the Corona Gods that this will happen. Because I got worried when I saw this.

In other words, the material does not get darker/brighter as you tweak glossiness.
But we already have a different solution for exactly the same problem in Corona which works just fine. Try to play around with CoronaMtl and you should be able to see that there is actually no darkening as you change the reflection glossiness.

If by "fix" you mean "remap glossiness"

Will the F0 dimming effect take place when the curve is removed Ondra ?
Title: Re: The most wanted feature?
Post by: Ondra on 2016-06-03, 01:30:19
we need a clarification. What we did is:
- remove dimming of glossy REFRACTION materials - already published in daily builds
- remove remapping curve of glossy REFLECTION - will be in next daily build

These two are not related - one is reflection, another is refraction. Reflection albedo is already remapped so it does not depend on glossiness, only on IOR/color
Title: Re: The most wanted feature?
Post by: dubcat on 2016-06-03, 02:15:05
So that's basically what I feared?
0 RGB Diffuse, 1.5 IOR and 0 Glossiness will still give 0.04 RGB after the curve is gone and not 0.02 like Unreal/Substance/V-Ray(GGX) ?

   I am from the VFX "market".I know a humongous number of talented artists that don´t move to Corona just because it lacks a SkinShader and a proper HairShader.
 
   The people that votes on those pools are NOT that people. Because they even started to use Corona... So, my vote if for those features... Even if it has less votes, it can potentially opens a NEW world of artists starting to use Corona, and talking how good it is, and doing awesome stuff around the globe, showing his works and carrying on the Corona Seal with it...

   This is much more than 2 features for Corona. At least from my perspective. ArchViz is already well served. There´s a lot to improve, but Corona is already at the point to be everywhere when you talk about ArchViz. It already broke the Vray hegemony on foruns and famous archviz sites... People that do ARchViz already look at Corona with good eyes...

    So, it´s my 2Cents about this. Bring more tools for Character and VFX worlds, just a few more, will bring much more $$$ and good propaganda to Corona.

If I'm not mistaken. What you have come to expect from IOR 1.5 GGX will actually look like IOR 2.1 in Corona at 0 Glossiness. 0 glossiness is kinda insane, but just to get the point across.

Correct me if I'm wrong, only speculating here.

I totally agree with these guy's! 

It always surprise me how programmor of render engine under estimate the importance of skin and hairs shader....   Do you think BLur would use Vray if it had not a skin and hair shader? The answer is no.. even though it's good for interior rendering.. without skin shader.. you can't use it in any VFX prod.. we always need skin and hairs shader in action.. I mean VERY OFTEN..

We need  a skin shader at least as good as ALsurface and the Alhairs for Arnold, not the standard one, it suck, we need this one : http://www.anderslanglands.com/alshaders/alSurface.html   this guy made awesome shaders.. don't know if you can get some help from him, but he's definetely good! The best skin shader I've ever so FAR ... in directionnal mode it's really good! and it's cool that it has 4 model to choose from also, plus all the control it has all over it's fantastic.

I cannot use Corona anymore since I do Characters mainly... so waiting for this since day one.. was supposed to be last summer I got told...  any idea qhen it will come out that skin and hair shader?

My impression is, devs are playing to the product's strength.
The way corona was built attracted the archviz crowd the hardest (No light tweaking, GI solution, that does not require a single change of any option etc. and is pixel perfect and flickerfree, etc.) so their voices were heard the loudest, since they are the biggest part.
However, since 1.0 all changes were universal in application. 1.1 Own Bitmap and Particles parsing, 1.2 smart displacement, 1.3 layered mtl, 1.4 denoise and adaptivity.
Before a more specialised feature like Hair can be addressed, there are couple more universal changes and fixes needed, like making glossiness curve not freaky and finally killing the Terminator bug in 1.5. Also in Buffer Bloom and glare are also universal.

Corona shyed away from fakes for as long as it could. Implementing Hair would finally break that philosophy, that is not a small step to take.

Lastly, I urge you write Ondra a hand written letter (https://forum.corona-renderer.com/index.php/topic,96.msg73985.html#msg73985).

Post by: cecofuli on 2016-06-08, 23:05:14
Honestly, before Triplanar texure, Light select Multipass, VFB improvement /postprocessing, CoronaScatter listener, I think that Skin/hair shader are much more important for the future of Corona.
If I think of the V-Ray history, they had VRayMtl+SSS, SSS, SSS2, SkinShader. In Corona we have only a very simple SSS
Then, they added a robust HairShader.
Only in the last version they have written the tools that, in Corona, we will have in the 1.5. Strange, uh?
Don't get me wrong, I will loveto play with new VFB PostProcessing tools, or the possibility to change in post the lights etc...  ^__^
I'm speaking as an arch-viz user =) But... they are "only" two small shader, but so, so important
I'm sure that after August we will see something interesting in the Corona Road Map.

I think they were rather clear that product that does one thing perfectly is better than two half-assed. They have grown incredibly recently, I have big faith that all features will come sooner than later.

Most people adopted Corona for things it did and had, not what they wanted it to have :- ) You buy based on your needs. Corona simply doesn't yet serve everyone properly. Some competitors were quick to do so and then no body was particularly overjoyed with result.
I presume people who need hair dominantly aren't after superior GI in enclosed spaces, so something like Arnold (which also brings simplicity to table) seems more rational choice in meantime.

Heck, look how fast denoising arrived :- D just 3 months ago Ondra told me it might not happen "because it does the same as adaptivity". Voila we have it sooner than Vray and it works fantastically.

Yeah... Corona get denoiser before getting a skin and hair shader... vray just got that denoiser thing also... like what, 1 month later or so? at least it has hair and skin shader.. any character artist like me cannot use corona.. it's that simple.. and there is a lot of studios doing characters related stuff.. in cinematic, film,etc.. hair and skin shader is as important as a base mtl like a blinn .. I really found it's a BIG minus for Corona to not have it..I'm not a programmor but, since Alsurface shader are open source.. implementing that into Corona should not be a mystery not take months.. and meanwhile they would get a LOT more attention to Corona then just having arh viz users...  They will see what I mean when they will finally get it doneone day ...

Hi,
What is meant by "Include reflections/refractions in render passes" ?
I guess (and hope because I´m going to vote it) it´s about having passes not occluded by refractive materials but correctly calculated instead (material ID, AO or any mask from objects behind glass for example). Similarly for reflections.

Exactly what i need since several years, maybe Corona can be the solution ,))

Somes images exemple for refraction :
01: 3dsmax Scene viewport
02: basic render with glass
03 : actual mask from red sphere pass
04 : refracted mask pass lookup

Thanks a lot

I don't know if this is the right topic to write this request, if not, than sorry :)

It would be really nice, to have Corona and Deadline work together in a better way. Unfortunately the tile rendering is not supported, and not working properly yet (as we have also discussed that at the EUE). Is it maybe on the list to make it work?

We are actually using a workaround now to make it work, but for that we have to turn off a couple features in Corona 1.4, which I personally love and I think makes ones life easier :) We wrote a script so when you submit your job to Deadline with tile rendering, it automatically turns off adaptivity and also turns the denoise amount in the original Beauty pass to 0 (so this way you can avoid getting seams from the tiles where they get attached together). To get the proper image, the UHD cache also needs to be rendered out separately and you have to load that in on all the machines for the rendering.

Now all these steps are controlled by the script, which sends out all the different jobs to the farm so they depend on each other and render them one after another. But while we get a much faster and smoother way of rendering images, we loose the nice feature of adaptivity, proper denoise and noise level limit.

So it would make us really happy and I think it would be a useful feature for many :)

I have spent the last couple of hours reading all the pages in this post and i like the fact that some features actually came from a user request .
I have a request but it is not a very ordinary request so brace yourself :)
I know I am going really old school here but bare with me ...Ever since unreal engine 4 was released arch-viz artists started learning it because it proved being really powerful in rendering architectural animations plus it renders in real time !!!
I think what unreal is capable of doing can be achieved in any other renderer with some simple tools !!!the main problem is reflections ,so i would like to see something similar to unreal engine reflection actors ,i am not asking for real time reflections but very fast fake reflections that doesn't have to be as accurate as raytraced reflections only it should look good enough to fool the viewer .
I know this might be against your philosophy but it can be really useful for architectural animations which is your main focus so far .
So basically i am asking for fake reflections that look very good and realistic and render very fast i think we can combine Gi baking (with render to texture) with fake reflections and render some very realistic architectural animations without going through the trouble of exporting the scene to unreal ...that can be a huge time saver .
This feature is a killer one that will attract arch-viz artists like a magnet trust me :)
Title: Re: The most wanted feature?
Post by: Juraj on 2016-08-05, 11:01:39

This feature is a killer one that will attract arch-viz artists like a magnet trust me :)

Why would it ? Setting up reflection captures like spheres and planes is absolutely counter to simple off-line rendering methods and the visual quality and accuracy is still poor. People use off-line renderers for simple workflow, perfect GI and AA quality and correct material behaviour.

What it could do, is screen-space reflection approximation (those are pretty damn accurate and good looking, although with screen-space limitation), but even that is absurd. In fact, this is something 3ds Max should do in viewport imho one day.... if they ever introduce true real-time one like the one in Maya.

Corona (and others like Arnold,etc..) are based on absolute physical correctness. We don't even have reflection/refraction depth and other bias methods, so why introduce something that's the brutest form of approximation that exists ?

Merging bicycle and car doesn't sound like the best idea. I doubt there will be any support for this.

(Disclaimer: I absolutely love Unreal 4 ).


Did you look into Art--> Stingray workflow in 3dsMax 2017 ? You can bake the scene and use the same shaders for off-line and realtime. But that's because it's two separate engines. Corona would have to write it's own new real-time core.
Title: Re: The most wanted feature?
Post by: MarsYellow on 2016-08-06, 13:29:34
Yes i agree with you using real time methods is not a good idea that is why I stated that I am not asking  for real time stuff anything similar works.....actually I am not interested in GPU solution at all I am interested in CPU solution .

all I am asking for is faster reflections without worrying about the physical accuracy if it is spherical actors it works for me if it is screen space reflections it works too !!(by the way the voxel cone tracing results are amazing for GI and reflections)

For example scanline renderer has a flat mirror shader that works only on flat surfaces -knowing it has limitations tells me that it renders faster than raytraced reflections- so the advantage of this shader is the fact that most of the reflections in an architectural scene happen on flat surfaces ex:walls ,and most of the render time is spent on those high glossy reflections so using this shader will save us a lot of time .
Here it is :
https://knowledge.autodesk.com/support/3ds-max/learn-explore/caas/CloudHelp/cloudhelp/2016/ENU/3DSMax/files/GUID-B6282DC2-8E18-4FE5-BEE1-819CFA154015-htm.html


I don't really know how these things actually work and if it is even possible to use for example voxel cone tracing in off-line
rendering but if it is I think it is something worth requesting !!

Yes I have seen Stingray but it is still young it might become something in the future but not just yet (The 3ds max-Stingray workflow is very smooth though )

I don't understand why "Include reflections/refractions in render passes" has so few votes.

Surely this is super important to anyone that needs to do quick edits in photoshop because the client suddenly doesn't like the shade of paint on the building, but you can't change it because some of it is behind glass so now you have to render the whole building over again.

Seems like a really necessary feature...
Title: Re: The most wanted feature?
Post by: Juraj on 2016-09-28, 18:12:58
Well 2 things:

Some things are bound to have less votes.. it's not like it has zero votes. It just has less votes then Caustics and other primary features. Just means more people would wish to have caustics than do advanced compositing. Seems perfectly sensible to me.

Second one is the name is unclear. I bet 70perc. of people have no idea what the "Include reflections/refractions in render passes" means in practicality. I surely didn't before you explained it on your example :- ) Now I want it, because it's frequent issue for me. Either I disable "visible in refractions" on glass, and then I have no glass mask and alpha, or otherwise. It's solvable currently, but with compromise.

Title: Re: The most wanted feature?
Post by: Dippndots on 2016-09-28, 18:39:17
Haha! Well I'm glad I could help explain it so succinctly! I would wager that the reason it has low less votes is due to the name not adequately explaining what it gives you. Truth be told the only way I found out about it was various threads here saying you should vote for it, if you want to solve the issue I described.

Maybe we can get it's title amended so it's clearer what it gives us?
Title: Re: The most wanted feature?

Honestly, most of those features are named from developer's point of view :- D

Non-homogenous volumetric media is something I would have to google right now.

I am more surprised that people vote for material presets. Do users of Photoshop vote for stock photography to come with the software ? It's nonsense feature imho, esp. that's what 3rd parties are supposed to come with (and they do, both Siger and Vizpark).

OK, please propose better names, I will gladly change them ;) I didnt know how to name some of the features.

Juraj: Siger and Vizpark show that there is a market for quality material presets. And obviously people do not want to pay or install extra for that. It is supposed be to provided by 3rd parties? Well, proxies, scatter, tone mapping, DR, ... should be too, but hey, look ;)

Dippndots (or rather generally speaking): good thing about this thread is that it forces people to face the reality that not everyone has their workflow and their preferences. It can get really frustrating when 100(*) people practically scream at you their requests with no reality checks - students with 16gig laptops request out of core because they do 50M uniq poly scenes, etc. Even better when they explicitly tell you to ignore other people so their requests get priority. I always found that extremely disrespectful. Look at the feature request section - half of threads start with "the only thing corona needs", "corona will never success without", "I cannot use corona unless it has", "corona will become extremely successful when you add". Same thing for fstorm or really any other renderer except for vray - which has threads "I like corona better because it has less features/controls", "vray has too many controls", ... :D - So here you have it - it is not that we developers hate you personally and wont implement your pet feature, its that people need (or think they need) different things and if 100(*) people request one simple thing, I would have to work for a year nonstop, and the result would be more complicated than vray.

For sure Ondra, I didn't mean to suggest it was more important than the others, just that it had perhaps been looked-over or seemed trivial because the description didn't make sense to some people.

Maybe a more appropriate descriptor would be "Masking Elements affected by material's transparency, e.g. adjust material id's behind glass objects"?

Non-homogenous volumetric media -> Volumetrics with variable density (Clouds, Smoke simulations, FumeFX)

Include reflections/refractions in render passes -> Refraction/Reflection considered by masking elements

These two are enough. Then people hopefully won't be confused anymore.

Unfortunately, results of the poll are probably already heavily biased due to the initial poor naming.

One thing I'd very much like to see, is a hidden line shader - preferably as a render pass.
I'm rather new to Corona, but haven't been able to find a method that works satisfactory. Coming from Vray, and I have often the use of their Vray toon to create hidden line renders. However, having it as a map/render element makes more sense. A possible solution would also be to add a "hide interior edges"-button in the WireTex map?
Title: Re: The most wanted feature?

Unless i misunderstood something, but Corona wire material already has ability to render hidden lines.
Title: Re: The most wanted feature?
Post by: robotmats on 2016-10-17, 13:48:09
I think you may be... it's not that I want it to display hidden edges in the mesh, but rather an "outline only" display. Typical Vray toon outlines render, or the "Hidden Line" viewport shading mode in 3dsmax.
Afaik, wire tex displays the full wireframe of the model.

It's lost in translation problem ;- ) Robomats doesn't want to render hidden lines, he wants them to be "hidden" :- D.

So yeah, basic toon shader/ outline only option to wire map.
Title: Re: The most wanted feature?
Post by: robotmats on 2016-10-17, 15:07:18
Thanks for making it even clearer, Juraj. I thought "hidden line" was a fairly well established concept in the 3d community. Another example would be the default viewport mode of Sketchup.

But yes, a basic toon shader (without the ability to do any cel shading) is what I am after. Very useful when the architect requests a "sketch" kind of visualization.

A temporary work-around, sure. But quite far from the sharp lines you get from, for example, vray toon. In any case: Being able to get this from Corona with a one-click solution would be extremely useful for me anyway.
And if you find the time to implement it, please make it possible to get it as a render element. In vray, you have to go through the trouble of making a separate render if you want a clean line render.

Main advantage of metallness PBR material would be that it wouldn't require textures conversion.

While it surely would be nice to have, i agree with Ondra - there's plenty much more important features waiting to be implemented.

(*) Skin shader
(*) Optimized hair rendering with dedicated hair shader
(*) Production-ready caustics

Why? Because they are something that we havn't at all.

The other options are a improvement of something that we already have.

PBR Style material (Disney, Unreal Engine, etc..) -> PBR material for metalness workflow, that would be more clear IMHO.

Not for beginners... If you are not experienced with the workflow, you may have not necessarily heard about metalness, but you may heard about some different shaders that Disney or Unreal Engine uses. It needs to be comprehensive for everyone.

Well this comes down again to the debate of "I WANT to use Corona" vs "I CAN use Corona". You are already sold on using Corona. But there are people who COULD use it, but dont because they see other renderers as being better. That is why just implementing every feature under the sun does not work - people certainly could use mental ray, since it has all features, but nobody wants to ;)
Title: Re: The most wanted feature?
Post by: cecofuli on 2016-11-25, 18:18:26
Yes, your point of view is good: better a few tool, but really good.
And, I can say: without VFX tools, hairs, skin, caustics, volumetric, a lot of artist will never use Corona.

In short : "we cannot have a drunk wife, with a full barrel"

Quite contrary, i would never know about some disney PBR if not Juraj, but word "metalness" is baked almost in every texture that uses this workflow and that should immediately ring some bells even for complete dumbass like me. Anyway, i think i can understand every option in this list, so i won't argue anymore :]

a question, what are the advantages of "Irradiance Cache/Map as primary GI" than our current primary GI solver "Path Tracing"?
Title: Re: The most wanted feature?
Post by: cecofuli on 2016-11-26, 16:53:41
It's like the  Irradiance Map in V-Ray: very fast is some situation.
For example , in interior projects with a few details and, especially, in fly-throught animations.
You can bake the GI every "n" frames and render these animations very fast!
Now, in Corona, we have to calculate GI every frame with the PT, even nothing changes =(  (only camera movement)

Yes, I know the metalness workflow very well from working with Unity, but I don't know much about Disney materials - exept some words from Juraj.

With the new Corona PBR (v1,5 +), I don't see the metalness workflow as an urgent need. A way to transfer Corona mats - or at least the bitmaps - to other engines (as i.e. Unity) seems much more urgent.

Keep it up :)

So there is a software called Motiva for vray it has some cool post production tools you should check it and see if you can add some of its sweet little tools to corona....maybe all of them.....or at least changing the color and texture of objects after rendering that would be very cool and useful for a lot of users I guess....or maybe just for me.....And maybe some post DOF tool based on zdepth or maybe on point pos pass .Yap and that is it for now....
thanks keep it up

Is it possible to create a material, that worked like a portal for camera (not for light)? So when we look on surface with that mat we can see through it on another isolated place connected to this portal. In this way it must work like a real portal.
This feature, for example, can be used in exteriors with big buildings with more windows. A real problem i see here - is a lights, i dont know how it must work in this case, because we have a some emmiters in isolated area, but it can be seen in many other places and it must influence on all of them.

Is it possible?
Title: Re: The most wanted feature?
Post by: Romas Noreika on 2016-12-29, 00:11:24
To have the option in the corona light to seperate effect reflection and effect speculars. I think this is critical to have - especially in production.

If I am putting a corona plane light in the scene or a IES (DISC), basically I do not want to see it in my camera or in my reflections, especially mirrors a w hite disturbing plane. I just want to get light, shadows and all the speculars from it.

Because honestly now in corona if you are putting a corona plane light in the middle of the scene, you will see that plane in your mirror reflections and else where. If you are diasbling effect reflection, at the same time you are removing all the speculars as well.


And also corona could have something very similar like VrayToon effect - because in production when you are making white renders for the clients, they want to see the model shapes clearly. If you are making just a clay render a lot of objects sometimes blends with each other, and you cannot not see where is what. If you are making a wire color - well that is an old school method which look very ugly when you have a bedroom and your bed DUVE is 1mil-2mil polys and you can see that in your wire frame.

What Vraytoon does, is showing only the shape of the models, Makes a contour around it. So you end up with a clean white/clay render + you can understand the model shapes very clearly. And the set up for it is very fast.

Honestly these two major things are still holding me back from swithing from vray to corona. If we will ever have these two features - that would be amazing, I think corona is an amazing engine and will go far, but there is much stuff to do. Till some people/studios will feel SAFE to migrate from vray to corona.

Best,

Romas

..I don't know why it's not a priority.
its simply because every features is important. and every users has their own perspective, this user need feature A more than B,C,D & that user need feature B, more than A,C,D. that's why ondra create this "most wanted feature" polling to help his decision making and prevent unimportant debates. feature which got higher vote number deserve higher priority.
imho no need to say why this/that feature is more important than the others.

Post by: Fluss on 2017-08-11, 10:03:19
you are absolutely right ! In that case, it's more a bug than a feature, mattes simply don't work as they should. They need to manage reflection and refraction, especially when the realease is VFX oriented. Indeed, that's my opinion :)

Add new feature is great, but they have to work as they should. I reacted on this one because it is one of the basics and it has to be done in priority imho. I understand that devs are not super heros and have to make choices. In fact, there is a load of things that bother me and that I don't talk because I know it's not the right time. Just sayin'

Maybe Fluss is right, masks don't work in their current state so perhaps it should be considered a bug and not a feature request. I can complete my work properly without caustics but without mattes I need hacks.

..yeah.. I see. i tried it and it doesn't work as it should, I remember it was already discussed somewhere here. it reminds me to compositing alpha mode in shadowCatcherMtl.

Not a switch, but a way to utilize the powerful processors sitting idle during rendering, which everyone already has installed in their computer.
At least to be used for something, to contribute along CPU, if not used for full rendering.

This has already been discussed a few times. We would like to move post processing & denoising to GPU. These should be quite easily implementable and would not require an extensive redesign/rewrite of the rendering core itself. Unfortunately we're still swamped with other work (debugging, implementing new features) and it will probably take some time until we have the opportunity to implement these.

Ondra, maybe we should put GPU post processing/denoising acceleration as a separate feature to the poll :)

There are currently two ways to do it I can think of:
1) Use 3ds Max native fog effect, which can be excluded from background
2) Change the "enviro distance" value in devel/debug rollout https://coronarenderer.freshdesk.com/support/solutions/articles/12000021288
Both are not perfect, but hopefully usable in some cases.

I was quite sceptical about this method, but i gave it a try and i think it's actually pretty good. I just would plug copy of CoronaSky instead of instance, for more control. Better yet, connect it through ColorCorrect or CoronaOutput nodes to have even more control.

Hi guys,

1. Will Corona be able to read VRscans materials from Vray?
2. Will it support Axf files, as they can be captured by x-rite device and authored in Substance? In product and automotive we are scanning more and more materials.

1. Yes. This is already on our roadmap, planned for version 2 - https://trello.com/c/oEFSRArR/126-v-ray-compatibility
2. Not sure about this. Does Vray support this?

very comfortable workspace:)))

A user like you has his own custom toolbar for fast access of most important things anyway, haven't you? This would be the apropriate location for some additional "render hidden on/off" button.

Putting everything into cVFB is not the best idea especially when redundancy would be created. Next request would be to put displacement on/off there and so on. Corona is really well integrated into max and uses the standard location(s) of the UI wherever possible. So it would be max (again) to blame if you struggle with your workspace.


Good Luck

Is this thread a good place to not just put my vote, but also ask politely about "Refraction/Reflection working with masking render elements (CMasking_Mask,CTexmap, etc...)"? :D

I don't understand how it gets so few votes. Aren't many people here doing archviz? Is it that people are moving further and further away from doing anything after they press the renderbutton?
I want to quickly photoshop stuff that into windows of buildings many times. And often there might be the glass of a balcony infront of the glass on the doors and windows. I know I could make two materials and have the front one not contribute to the mask. But what if I also want that one as a separate mask?
In the attached image (multimatteelement from vray) I have an inside of an atrium in an office building. And I needed masks for both the glas on balconies, and a mask for the facade/outside.

I just wanted to add this as an extra little "pretty please" because I think more spectacular features get more votes, when this might be easier to implement and definitely really usefull :)

From my point of view, it's really important to get Corona as flexible as Vray, post-production wise. For example, users of PSDManager are a bit limited for now (no scene layers output, anything bound to GBuffer ...), so we heavily need an alternative.

Just a few simple suggestion:
- Albedo warning could be an option in the VFB. I think no one wants to save it as a render element, people only want to know if a material is wrong.
- Corona Object Properties (diffuseion level, brightness, contrast, gamma, saturation). Just imagine a when you import and convert for example a bookshelf with dozen of colorful and white texture maps, how simple it would tu decrease the saturation and diffusion level of the books with one click, instead of going through the material one by one.

These aren't bad at all :- ) I like your thinking ! All those hundreds of books with wrong shaders : / and all of them multimaterials, I don't even know which book I click on :- D But this is something for maxscript I think.

A FullHD pic means +16MB RAM, a 4K means +64MB RAM, I think it's not much. Displacement, Proxies and those hundreds of textures eats the RAM. When rendering is out of memory that 64MB won't save anybody's life...
Title: Re: The most wanted feature?
Post by: Ryuu on 2018-04-18, 10:28:14
The thing is that you'll have 8 bytes per pixel here, 4 bytes per pixel there, 1 additional byte per instance isn't a deal breaker either... and in the end you have a death of a thousand cuts and no single place where you can do any memory significant savings.

64 MB can still be pretty significant in situations where the scene almost fits in the memory.

I definitely agree that this should remain an opt-in feature. Maybe it would make sense to add some kind of "there's probably a wrong albedo somewhere in the scene, add albedo element to find out" warning in the future.
Title: Re: The most wanted feature?
Post by: romullus on 2018-04-18, 11:26:51
Exactly, those megabytes adds very quickly. And if albedo will be permanently added to VFB, i will definitely ask for sampler info pass as well, because that info is much more useful to me than albedo :]

The specular Pass is not just a approximation of reflection, whatever that means, it is the highlighted area of reflections.

Non the less if people are asking for it why not have it? it improves peoples workflows and post production retouchers here keep asking for it.

No one said it has to be removed from the reflections pass.
Title: Re: The most wanted feature?
Post by: TomG on 2018-06-22, 13:42:47
There is no such thing as specular in Corona though. This is what the previous poster meant - in the real world, there is no such thing as specular either, it is purely reflection, and Corona works the same way. Specular was something invented in computer graphics back when doing full reflections was not always possible (hardware wasn't what it is today :) ) in order to give a faked impression of the reflection from a light source, and was a way of faking what happens in the real world; and it's a fake that Corona does not have - so I would guess a specular pass is impossible, since there is no specular in the rendering.

Not sure if doing some post processing on the reflections pass, to filter it to particularly high brightness, would give the desired result, but it's the closest thing to what specular was faking (reflections of bright light sources). Of course where specular faked it with always perfectly rounded shapes, the reflections pass would have the actual shape of the light source in there, so still not exactly the same :)

YES! Exactly my thoughts. This is the new gold standard. At the VFX company I work at, Scanline as a look dev and lighting supervisor, over the last year I've been hard at work slowly converting everyone over to PBR, and it is yielding fantastic results. Much better looking assets that behave much more predictably to physical lights than the old diff/spec work flow.
Title: Re: The most wanted feature?
Post by: Ludvik Koutny on 2018-06-23, 07:46:45
PBR will only change workflow, not really output quality. There is nothing that *looks* better with PBR, it just makes good looking things a bit easier to set up if your input is PBR set of maps. But talking about just a raw material, anything an average PBR material, such as Disney PBR, can do, can be replicated using CoronaMTL.

If we are talking about Principled material, then it's really just a workflow difference, not quality difference. Of course, I am not implying we should not have it. I am just saying that it won't make anything look magically better.
Title: Re: The most wanted feature?
Post by: Njen on 2018-06-23, 11:28:16
No one was questioning whether the CoronaMTL can support PBR style shaders. Setting up PBR style shadering standards is possible in any renderer that supports GGX or a similar microfaceting BRDF, it's not just a Disney PBR thing.

There's nothing magic about it, and it's not just a workflow difference. But the results speak for themselves: less time to set up when adhering to energy conservation guidelines, and surfaces that behave more physically accurately and scale linearly in response to light exposure changes which leads to less work to tweak in comp to final a shot, all adds up to an increase in the quality output of work.
Title: Re: The most wanted feature?
Post by: Kalopsia on 2018-06-23, 13:14:16
PBR! Cmon everybody! Sing it with me now! PBR!

Don't we already have PBR with the GGX Shader? What else do people need. If I remember correctly, Corona did even adopt glossy Fresnel before Vray.

As for the Albedo Warning, just create a MaxStart file with all the elements you use the most. Done.

I would rather want to see the new adaptive Dome inside Coronas Environment, so no portals anymore. That would be a nice thing.
While we are at it, some override so you can drag images into the Material Editor and they are Corona Bitmaps instead of the default Max bitmaps. That would be amazing.

As for Cryptomate, it would be great if you could use it inside of CIE and simply select colors and save masks.

And can we pleas get the Corona Frame Buffer to load the monitor ICC profile automatically or at least an option to do so like in Vray.

Oh, and stop deleting the history when closing a scene. I never understood the point here, why not leave it saved until you decide to delete the images.

I'll stop now before I get even more ideas XD
Title: Re: The most wanted feature?
Post by: Lord Kelvin on 2018-06-29, 02:05:11
People are confusing PBR Glossiness with PBR Metalness.

Corona has PBR glossiness, the current vote is for PBR Metalness workflow (PBR Style material (Disney, Unreal Engine, etc..)), something that Vray currently has.
It would be better to rename the vote to Metalness Workflow, or something like that instead of PBR.
Trust me, it's about 1000 times more convenient to generate a specular map than an IOR map. Specular maps specify the reflectance value in linear.

Diffuse roughness is the most important feature Corona is missing (hello fstorm), when it comes to photorealism. Every major studio knows this. The next best thing is to have an easy and convenient way to map reflectance values. PBR Glossines is not enough to emulate real world specular, we have to make IOR/Specular maps to fake depth. Specular maps are most convenient when it comes to real world scans.

The first problem is that there is no "Diffuse Roughness" in the Poll! This feature is like "Boar Vessel, 600-500 BC, Etruscan, ceramic", something that real men want, but never accomplish to get!

This is a daily problem for surely pretty much everyone. Would be a huge, huge productivity booster.

How about, if it's not accurately solvable (as in, not feasible), a work-around - a switch to say, ignore all refractive materials in this mask element? Not unlike your material override refraction switch. Same principle...

I'm so happy with Corona, but the following three features would make it unbeatable:

2) Completely automatic import of Vray models and scenes. Still ways to go.

I would not expect the devs to jump on the GPU vagon now, esp. since they never wanted it, and now Vray is focusing more and more on it.

They did promise at least off-loading the framebuffer&post onto it in some way, didn't materialize yet in any way either. But Optix is kick-ass ;- ).

Would be nice though, let's see how fast Vray is going to be once RTX embargo is out and Vlado can disclose some benchmarks.

Its true that they never wanted it. But lets be honest, Its becoming more and more apparent that its the cheaper way of operating and scaling your operations.
If i wanted a new render node id have to shell out a few thousand for a dual xeon node. Or i can pay around a thousand for a new gpu and pay less in terms of power draw too.
I just think with fstorm becoming so popular since they won the lawsuit and large chunks of free models being released exclusively for fstorm and with vray showing more gpu rendering is it not a worry that eventually the cpu renderers would get left behind just because the cost of setting up a gpu farm can be alot less?

Nvidia are really keeping their cards tight to their chest with the embargo on RTX but i kind of agree with what some people are saying that this could be like PhysX all over again where it never really became an integral part of the gaming experience. However it would be interesting to know what impact tensor cores could have on rendering applications if any.
Title: Re: The most wanted feature?
Post by: Juraj on 2018-09-17, 12:29:19
Yup, GPUs definitely have better future in rendering and it's much easier to scale it.

But then again...look at what nVidia introduced... massive overpricing. To get the most out of GPU rendering, you would need Quad (two pairs of NV-Link to get memory pooling) 2080ti= 5200 Euros + price of workstation.
So majority of people will not be able to afford it either it's just that at certain high-price point, GPU overcomes CPU in price/effectivity a lot.

Truth be told I thought cpu rendering could be dead by now...but imho 32-core 2990WX is much better progress than 2080ti itself. In next two years, I fully expect 48-64core 3rd/4th gen 3990/4990WX getting another massive 100perc. speed boost while I only expect 7nm nVidias to cost even more for even less speed-up. So the competition is strangely equal right now and people should stick with what they have right now and see how it unfolds.

But since most of us have at least one GPU in each PC, it's shame we can't use it to anything.

If you read our announcements carefully, you can see we are getting more and more open about the possibility. If you look retrospectively at GPUs and technology available 8 years ago, you will surely agree that doing CPU rendering then would be unfeasible. Yet even then people claimed CPU rendering is dead and GPU future is right behind corner.

Since then GPU rendering got better and better, but with smaller, incremental steps, there is no clear "switch now" moment. I am lot less nervous about this now since we have large GPU team inside Chaosgroup that I can consult on the feasibility and how-to of GPU rendering. This might be the biggest benefit of RL-CG merger for the future.

If you read our announcements carefully, you can see we are getting more and more open about the possibility. If you look retrospectively at GPUs and technology available 8 years ago, you will surely agree that doing CPU rendering then would be unfeasible. Yet even then people claimed CPU rendering is dead and GPU future is right behind corner.

Since then GPU rendering got better and better, but with smaller, incremental steps, there is no clear "switch now" moment. I am lot less nervous about this now since we have large GPU team inside Chaosgroup that I can consult on the feasibility and how-to of GPU rendering. This might be the biggest benefit of RL-CG merger for the future.

Interesting. Do you guys feel there would ever be that switch moment?
Perhaps when GPU prices settle back down to where they actually should be rather than a good 30% above what the RRP should be?

30% is not enough to switch, it would have to be lets say 10x. Or solving some outstanding issues of GPU programming, such as lack of function pointers, bad scaling with complexity/divergent code, etc. Or just going step by step. We are in contact with VRay GPU team and we are discussing this from time to time.

What is the status of Optix support in Corona?
Title: Re: The most wanted feature?
Post by: sebastian___ on 2018-09-17, 20:48:26
When/if Corona would add GPU rendering - it would be ideal if it would be a seamless experience. I mean just add another CPU and another GPU and watch your rendering gets faster and faster. No Corona split in two like Corona CPU and Corona GPU.

 And if the GPU would be hard or unfeasible to program in a way CPU is, then the GPU should be used at least for the operations in which GPUs excel. So some things would be done by the CPU and simultaneously the GPU would start doing those other things which comes easy for a GPU. And I don't mean just the post effects, but maybe some parts of the shading or lighting or I don;t know, cause I have no idea :)

That is another topic. There is not a single renderer on the market that sucessfully switched from CPU to GPU rendering. There are probably some reasons behind this. One might be that you not be able to get full feature set of a CPU renderer on GPU. At this point I think it would then make more sense to remove the same features from CPU version than keep 2 renderers with 2 separate feature lists. And I think most people would still not like it...
Title: Re: The most wanted feature?
Post by: Benny on 2018-09-18, 02:57:53
But isn't it possible to have a supplementary strategy, like Optix for noise or just having the GPU doing some other taxing task?
Title: Re: The most wanted feature?
Post by: Ondra on 2018-09-18, 09:57:44
that was also never successfully done. The overhead and synchronization just makes it not worth it. You would have to transfer tens of gigabytes of data per second between CPU and GPU to make this work, and you would be limited by the slower component of the two

People do seem very excited about the approach Blender is taking with Eevee though. Using a realtime GPU viewport renderer for IPR, which then often is good enough, with the option to do an offline render in their Cycles. The differences between the IPR and final render are outweighed by the relatively high quality of the viewport.

Being a non-programmer I actually can't understand why Chaos isn't taking a similar approach with Vray GPU, i.e. a viewport version. But perhaps Turing will allow that.

I think at least one renderer does this, and probably others too. Arion render has the so called: Hybrid acceleration (GPU+CPU). So you don't have to choose and use two different engines, just use CPU if you want or GPU or both.
And I think I remember reading on the news that newer versions of Vray can do this too ? CPU contributing along with GPU ?
Title: Re: The most wanted feature?
Post by: Ondra on 2018-09-19, 13:29:07
I dont really know Arion, but I should have qualified by previous claim to renderers with significant user base ;). I can totally imagine switching Corona to GPU rendering if it had the featureset of 5 years ago, but renderers with bigger general userbase usually accumulate significant extra features that make switching hard. VRay did not switch to GPU rendering, instead it has now both CPU and GPU as separate engines. This means double development teams, support issues, etc.
Title: Re: The most wanted feature?
Post by: sebastian___ on 2018-09-19, 17:07:53
Fair enough with Arion user base and maybe Thea Presto also...
But doesn't Vray have a new mode of rendering involving both CPU + GPU collaborating on the same render ?
And I mean as some new type, after Vray v3.5 I think. So this was some new addition, and new way of hybrid rendering. And not just the regular GPU rendering in which of course the CPU will also sort out the geometry and do some 5% processing also.
Title: Re: The most wanted feature?
Post by: Ondra on 2018-09-19, 17:36:47
the hybrid mode is CPU and GPU computing samples separately and then combining them in the image, it is not one rendering process split between the two. So yes, you get both CPU and GPU busy, so the rendering speed is CPU+GPU, but it cannot be used to circumvent weakness of either part (which is usually what we talk about when thinking about hybrids - like evaluating all the complex shaders on CPU and using GPU just for its brute force).

Interesting to know. IMO Hybrid for Corona could be great with the new ray tracing on Turing.
The idea would be to use Tensor cores for ray tracing that is instant, so you could calculate UHD Cache in realtime.

This might be used like the new denoiser you guys are working one. So in general we could use GPU for all sort of additional calculations, like bloom, glare, or even displacement.

But I guess we will have to wait and see where NVIDIA is going with this.

Hi everyone! I am new to your forums,

I represent a small 3D studio and we're really happy with Corona, we used Vray before, but we feel very limited with the current Corona Wire Map.

I see there was previous discussion on your forums regarding Toon Shaders, but it would be great if you guys could come up with a better solution with more control and the ability to outline shapes and geometry easily.

We have a lot of customers asking for schematic drawings and we currently have to use Vray Toon Shader to achieve the look we need, similar to the assembling manuals of Ikea.

That's it, thank you!

+ 1 for toon/sketch shader. Im working with inhouse ArchViz and cityplanning, and find it cumbersome that Max+Corona can't deliver the "SketchUp" style that's being asked for again and again.

Please make it, and please make it soon!

Tensor cores are used for AI processing. RT cores are the ones doing the raytracing. CUDA is a third type of core where business is as usual.

That being said, I wonder if AI denoising, something like Nvidia Optix could be used for Corona.

On a side note - I've got a pair of 2080Ti GPUs and in FStorm those bastards render at the speed of 4-5 1080Tis / Titan XPs...which is mental. I'd love to see the RT cores put to work too, but Andrey said that they're pretty useless for production rendering since they only work on standard triangles (so no fur, voxels, etc). Shame, but Turing's CUDA speed is pretty damn impressive as is.

Can we not assume that stuff under the hood like making memory/speed/displacement better and existing features better is a given?
It just seems that it might make more sense to use the poll to vote on new features so they dont get buried by the obvious and more permanent ones that have been on the poll for a long time and everyone wants?

Like we all obviously expect Memory optimization  Displacement improvements and Speed improvements each major version dont we?

I completely understand. I do still think though that having the ones i mentioned on the poll is a little odd considering we all would expect things like memory improvements and speed improvements version to version anyway. If they werent there then people would have to vote for some of the other features which maybe are just as popular but havent been on the poll as long to accrue so many votes.

Coming from using Vray for years we're starting to bend towards Corona more and more.

What I love about Vray - and HATE in Corona is the way the Corona VFB handles renders.

If you store an image in the Corona VFB history you can only save out the base image.

Render elements aren't saved into the history so you can't save out any render elements.

In Vray - If you double click a render in the history, it opens up in the VFB (and loads elements in too).  You can then 'Save All'

In Corona I don't think you can do it.

Is there a fix/workaround for that?

Don't want to be mean, but is this the case :) ? Slicer-clipper was postponed at least for 4 major releases now.

We got into this trap of starting an ongoing project in Corona because clipper was due to be released in the next upcoming version and now we have to resolve to cumbersome workarounds with distance maps...

This was more of a rhetorical question but thank you Romullus.

Just wanted to point out that people working on a specific rendering engine try to streamline their work and optimize it (yeah capt. obvious :] ). Switching from for example Vray is a huge commitment of time and therefore money investment.

I of course understand that huge amount of people want huge amount of features and having limited resources (developers) the company has to choose which ones to implement at a given time taking into consideration all the factors that you mentioned.

But telling people that something will be done and not doing it for over a year (I think clipper was due to be released in 1.6) is not entirely Fair in accordance to FairSaaS in all of its glorious aspects ;)

And clipper is just an example here. Just trying to figure out what is the key factor that pushes any given feature into production. For example Disney material is at the top of the poll in this topic for a looong time. And it just sits there :)

-They spend 100x more time thinking about these issues than any customer ever will.
-And based on what I've seen, the Corona team is also working very very hard and they have absolutely no reason not to build the best product they can.

I know, as a customer, there is a small set of features that are disproportionately more important because of your specific use case, and it can be very frustrating when the product priorities don't align with yours.

Just remember that there are hundreds of use cases and hundreds of "hidden" complexities in running a business and building a product.

This is not to say that we as customers should shut our mouths and just wait for the dev team to do their best, but I find that complaining is not the most useful thing we can do, here is what I think it's better:


- Understand WHY a feature is not here, sometimes it's not used by enough people, sometimes it's too complex to build, and in some rare cases, the feature is being overlooked by the dev team.
- Build a strong case on why a certain feature is important and try to get more people to support the idea and help the dev team see something they might be missing (like a market trend, new tools, new workflows etc.)

In the end, I don't think neither this poll nor the trello should be used to inform future jobs we take, we should use them as tools that reflect vision and trajectory, as I currently interpret both of these are:

The poll: People are liking the results from Fstorm and other GPU renders and would want to have those goodies in Corona too. (geo pattern, tone mapping, gpu) Second, the industry seems to be moving to PBR and people are starting to miss proper PBR support in Corona.  Most of the other items seem to have niche support and not general support.

The Trello: Seems like the Corona team is focusing on closing on "essential" features before jumping to new features: stable light solver, caustics, clearcoat, volumetrics. These are MUST have features for any production-grade render. This is a sign of maturity for the product. 
 
I don't expect they will focus in too many new features until Corona is stable and robust as a production render, something a studio can pick up knowing that it will work for them 99% of the time and they won't need to hack or fake stuff out, or switch renders in a few years. Once that is solid as a rock, I would expect they would start exploring things.

Exploring things means breaking things, and when client's livelihood depends on your product, you can't be as aggressive with new features. Fstorm can get away with whatever they do because pretty much no one is using it for "serious" work.

Really good response there and it makes sense to do whats best for the company. I think a fair bit of frustration from what ive seen comes from the development fstorm has in some areas and its just one man doing the dev. It seems fstorm has stuff corona doesnt but corona has more necessary and production ready stuff than fstorm.

I agree that it seems ridiculous that some features get pushed back release after release. I originally asked for the clipper in 2014 i think. But there are some features like a proper PBR material and like Geopattern or Reworked tone mapping that make larger parts of the production pipeline easier and id rather have those completed first. Clipper would make a very specific part of the workflow easier yes. But it wouldnt make as much difference as a proper PBR material would.

Really good response there and it makes sense to do whats best for the company.

I agree that the company must do what is best for itself. We as companies or freelancers do the same. What I do not understand is why from one point of view people say that we as the users should not keep our mouths shut about the development and on the other hand each time someone decides to speak up some other person appears arguing that there should be no complains because the corona team does super job providing us this great plugin.

I agree that Corona is great. I love working using it. I respect the developers. But we are all buing a product here, and doing so in SaaS way part of what we pay goes to fund the development.
So the everlasting narrative of being eternally gratefull to the Devs for doing their job that some people present is getting irritating.

I would love to meet Ondra some day for example in Venice and talk about ponies and stuff over a beer or something and make friends. But I firmly believe this kind of stuff should be done off the forums ;)

If a feature was promissed and it doesn't get delivered I do not see a point why users should not talk about it.

Clipper would make a very specific part of the workflow easier yes. But it wouldnt make as much difference as a proper PBR material would.

I completeley agree. I asked a question about this in the daily build section but it wasn't answered. I also believe that the product should be built logically from the ground up. If proper PBR shading is a standard these days such shader should be IMHO one of the first things to implement so users building their material library won't be forced to rebuild it as a whole and reshade all their assets, and instead build them with correct shaders from the beginning.
Same goes for tone mapping.

I also would have those features paired with mentioned geopattern sooner than even mentioned clipper. Clipper was just an example here.

Just a quick note, no-one should keep their mouths shut :) We do always welcome hearing requests, whether that is for something never asked for before, or a request that someone notes "I first asked for this back in 2017". We don't take that as criticism, just as a reminder.

That said, we do ask that people understand that their request is a request, and while we do listen to and consider every request, that won't always mean we implement every request; and that people keep in mind that prioritizing development is a balancing act between a lot of different considerations, so if we do implement something, when that happens may be quick or may take a long time, or even may change (we think we can do it, but other things come up in priority and it gets pushed back). So, feel free to remind us it's a long standing request, but please don't yell at us :) Which I don't think anyone has been doing, to be honest, it's all been respectful. And I think the system is working well for both developers and users!

maybe they got instructions from above, maybe... i will just shut up.

AKA Vlado?

The amount of new features that Vray had since they joined forces with Render Legion is impressive. It made a come back.
I don't know if it was just a coincidence or not. But I really hope Vray is not taking strength from Corona.
Fstorm reminds me of Corona before the merger.
With that said I love Corona and have nothing but respect to the Corona team.

Thanks for taking the time to answer Tom.

One more thing I wanted to add. As I mentioned before I believe that people invest a LOT of time by committing to a specific rendering engine.

Therefore I do not agree that any Road Map should be treated loosely. I believe it should reflect the development road as closely as possible. Even further than the next upcoming release.
In that way noone gets disappointed in the long run, because he or she can check if their personal vision of  developing their own company alligns with the development road of the engine they committ to.
This will be of course more or less of an interest for different people depending if they do more specialised niche type of services or just general rendering.

And concerning hobbits, I mean roadmaps ;) When can we expect an update to the existing one ? Are you guys close on deciding next things that will get done ?
Title: Re: The most wanted feature?
Post by: TomG on 2019-01-04, 16:52:30
That's a good take on the roadmap, ty for the feedback on that. I will have to leave it to the developers on how close it is to seeing an update based on latest thinking about what can fit into Corona 4 :)

On the previous post, the merger has not changed our team, and the Chaos Group and Render Legion teams are separate. They don't cannibalize time or people from each other, we just share ideas. So no, V-Ray is not taking strength from Corona :)

On the comparison to FStorm, just a note that it much easier to add exciting new features when a render engine is younger. As it gets older, the big ticket items are already done - but also the platform becomes much more complex, and adding a new feature means making sure it doesn't break the other 1,276 features (while when earlier in development, that's "make sure it doesn't break the other 312 features"). Again, the merger has nothing to do with this, just to do with Corona Renderer being a more mature product now, and the associated caution that has to come with the fact that many production studios are relying on it so we have to be super careful not to break anything people depend upon. Hopefully this puts your mind at rest :)

EDIT - also, that means that change is not to do with the merger either, again it's just to do with maturity and all that comes with it ;)
Title: Re: The most wanted feature?
Post by: lupaz on 2019-01-04, 17:16:31
Got it.
Thanks Tom.
Also Fstorm is being pushed by the innovation in GPU, which doesn't seem to be as fast with CPU unfortunately.

"Caution"...I'm not sure I like the sound of that :)

I totally understand. And I wouldn't like a bloated software either. In fact, the material library is something I never use for example.

As you said corona is a well rounded engine. It works great.
But I would love to see what is that long term research that I heard about.
It would be great to have improvements more than features too. For example, a better AA, or better bump mapping, or a better BRDF. (please note I'm saying OR, not AND)
I can see how those things could break the code, but I wish the team lots of courage :)
Title: Re: The most wanted feature?
Post by: TomG on 2019-01-04, 18:01:26
Ah, well by "Caution" I just mean "extensive, very detailed testing and QA" - not "reluctance to do something" :)

Post by: zokni on 2019-01-05, 02:37:37
The opinion of a guy:

Let me tell you my honest opinion, after that anyone can kill me if he/she wants to.

First of all, I love to work in Corona and I respect you guys. I worked at a software development company for a longer time 120 years ago I know a little bit how things go.

I use Corona every day in the office. Almost a year ago, fortunately I was able to persuade my boss to switch to Corona from Vray.
I was a subscriber as well for a long time, much more than a year as far as I remember.

But how the development goes it makes me a dissapointed. Lets see what happened in Corona 2 one by one with all my respect.

- Advanced camera/bokeh effects - Nice, thats what we like to see, it adds to the overall quality, unfortunately our clients atm don't really want to pay for closeup DOF shots, but its a nice feature. I don't really use it, but thumbs up.

- Corona toolbar - Cool, it should have arrived no later than in Corona 1.3

- Memory optimization - Adds nothing to the overall quality, not a new feature, it helps people who have less RAM.

- Heterogenous media - Long avaited feature, I know, but in archviz (main platform I think most of the guys here from that field) in 99% of the projects good for nothing.

- Vray compatibility - Nice to have that but overall its good for nothing, not an important thing to have. We have a nice converter, I never use Vray stuff in my Corona scene I always convert them from Vray before I merge. Probably it was a "request" from Chaos Group so we can understand that. But again, nothing new, doesn't speed up your render, adds nothing to the overall quality.

- Corona Material Library Update 2 - see as above. (not a new feature, adds nothing to the overall quality or speed. (OK, not completely true but if you are not a newbie you know how to create nice shaders).

- Bugfixes - Always nice to have those.

- Displacement optimization - Cool.


For me, that was the point, after Corona 2 has been released when I cancelled my personal subscription because the reasons I've mentioned above.

Now you guys have released Corona 3 and the main new feature is the denoiser what is a generic thing (I mean it's the implementation of nVidia's technology, it's a common thing these days, if you have it cool, if you don't it's a shame), the rest (according to quality or speed) nothing too special. Autombump is nice anyways.

A like to work with the real time denoiser in the office so I have decided to renew my personal subscription as well but for me, thats the only real advantage of Corona 3, the other things, like the new multimap feature or the another Corona lister are nice to have but with a little bit of more work or with 3rd party thingies you were able to do those before Corona 3 as well.

I can only hope we can see something really cool in Corona 4 what finally would add some real thing to the overall quality. (like PBR thingies, caustics, tonemapping, or things like Geopattern)

I would love to hear some response from you.

Peace and I love everybody.

You forgot the improvements of SSS. It got much better and is a major plus for realism.

I have the impression that the vray compatibility and all the openvdb and Inside volume has to do with Chaos Group wanting to sell PhoenixFD.

Your comment was a little bit different before you've modified it. If you don't share your opinion things will never change, thats why I did it as well. I would like to find out if I am the only one out there with that opinion or not.
Nothing bad will happen if you tell them the things, nobody will ban you or cancel your subscription. I would like to make Corona better, thats all what I want.
Life is pretty simple, they sell something, we buy something.

Who else share their opinion with them if not us?

I felt I wasn't being constructive.

In any case, I think they get the picture:
We're frustrated with the recent development not being targeted towards archviz, or there's no development towards improving the quality (realism).

In general it seems that innovation stopped. Compare features in 1.5 and 1.6 with those of 2 and 3... It's pretty obvious to me.
Title: Re: The most wanted feature?
Post by: Jpjapers on 2019-01-07, 00:48:35
I agree that there seems to be a fair chunk of development in areas that the majority of the user base (at least based on the cross section of this forum) would rarely use or notice in an already powerful and fast render engine and there seems to be less development recently on things that would make the renderer more competitive and useful to its archviz user base or at least the majority of it.

For example 2d displacement, clipper and pbr material have been asked for for a long time. Autobump and openvdb are cool but nowhere near as useful in the majority of cases. I completely understand when Tom says they have to be careful not to break the core features of corona we all rely on day to day to make money so smaller features are obviously going to be less risky than overhauling the way corona outputs colour or handles pbr. Having to take a 'roll your own' approach to pbr in the mat editor is just a little cumbersome however and there's no doubt in my mind that the corona team are considering it for a future release. Hopefully v4.

 Archviz is such a huge part of the user base here obviously and there are features that should have priority that have been pushed back release after release. It feels as though the thing that brought so many to corona was the fact that it fit so well in the Archviz pipeline but for taking that huge commitment of converting an entire production house to Corona there seems to be little payoff in terms of new archviz-centric features since v2. Perhaps we were spoiled with them initially.

I emplore the devs to be a little more open with the user base about what features are being seriously considered for each release and what are less likely to make it into the next version. its only recently more and more users here have began voicing these frustrations. I feel they are entirely justified considering how often large features from this poll are missing from major releases despite being highly voted for years.

Just as a closing note I said it before that memory optimisation and speed improvements shouldn't be on this poll at all as it should be expected at each release. When the poll was reset i mentioned this because they were dominating the poll and yet again they are scoring highly and it feels like a waste of a vote. It subtracts from what the thread should be about. New features.
I also still think a 'small annoying things' thread would be great for voting on smaller workflow adjustments that aren't new features or bugs.

This is all with the absolute highest respect for the team and the work you do. For. me, corona has made working in 3d so much more fun and creative again and for that I thank you!

We definitely could use a more trustworthy and reliable development roadmap (trello).

I am pretty sure I am not the only one who checks trello time by time for the planned new features. It even worse (it happened to someone else I don't remember who was it) if you make some project plans according to the promised features and then that feature cancelled later.

Again, I know its easy to say, much harder to do. More or less I know why it is like that, sometimes you change something and 20 other features will stop working and the deadline is a deadline for everybody. But try to be just a little bit more accurate with it if possible.

It is very disappointing when you promise a feature (caustics is a good example) in every major release and then it just pushed forward and forward and forward.

I am not calling you to account I am begging, please work together a bit more closely with your customers and try to listen more to their requests.


PS.: One more thing. Probably you have already noticed that from my grammar that english is not my native language. I was born in eastern Europe and that time Czechoslovakia still existed.
I exactly know what meaningless polls mean.

Agree on most things in at least 10 previous posts.

We are the ones tat got backlashed by this trello-promise of clipper/slicer. The thing is, at the time everything that was on the trello road map was pushed into stable releases so we had no reasons to restrain ourselves from taking it serious :)

Maybe the team wasn't aware of how serious people take this kind of stuff.

Anyway, our fears/doubts are voiced. I encourage everyone that feels the same to speak up, and in the meantime I'm eagerly waiting for the update of the road map or at least some kind of real debate on what features the majority of users would want implemented in upcoming releases.

Howdy all!

Great to hear your opinions, ty for sharing those! A few thoughts in reply :)

- Software developers have two options really - say nothing about what they might be working on to save disappointment when things change, but it leaves all the users in the dark; or be open and share what we are / might / would like to work on, which keeps the development process open to users but then does have disappointment when things change (and it's always WHEN and not IF, things always change with software development).

We chose the second, but of course that has the catch that then people can get upset if something gets moved back. We still think that is the "lesser of two evils" and so we'll continue to share. We do our best to keep Trello updated, we'll see if we can improve how we do that.

No matter how much we improve it though, Trello or any other announcement of things we'd like to work on - or even things we are working on - should never, ever be taken as a promise, as someone called it. Even a long way into developing something, it can all be found to be unworkable and have to be abandoned. So, we will share what we are doing, but do please remember the realities of development when share. We can't stress enough that it is usually impossible to promise anything in development, and so we never do, until it's actually in a release :)

- On features and their priorities, everyone always has their own opinion. For example, there was an opinion here that the NVIDIA Denoiser was really nothing major, just something generic. Well first, it still takes a lot to implement it, just because it is NVIDIA's Denoiser doesn't mean making it work well with Corona is trivial. Next, in fact, our implementation is better than most ;) We get good denoising in reflections and refractions, that is not always achieved by others using the same NVIDIA denoiser.

And next, this "just a generic feature" to one person is a huge game changer to others, as we've heard from other users. So what is the greatest thing since sliced bread to one person, is just some generic feature to someone else. This is true for all features of course, the NVIDIA one is just an example. We could pick the material library too, also said by someone in the post to be not very important except for newbies, while we've heard from major archviz studios that it is an awesome addition.

So in that regard, the last few releases have had their features that many DO regard as game changing, and critical to their workflow (and yep, that's archviz workflows!) Everyone will always see a feature differently. You can't please all of the people all of the time, as the saying goes :)

- Don't forget that we also mentioned a lot of work went into things behind the scenes to improve stability, and clean up the code base. This becomes necessary once the software grows past a certain point (if you want to keep the code stable, easy to add new features to with a minimum of risk of breaking things, and so on). Sure, we could avoid doing such "busy work" as it isn't very visible or exciting, and pile new feature on top of new feature, but this brings a lot of pain and hardship for users down the line (I am sure everyone can think of software where this has happened, and is aware of how that plays out!)

This kind of work may not be that exciting in that release, but it sure is exciting further down the line when innovation can continue!

- We ain't done being revolutionary and groundbreaking :) Whether the last few releases have got you excited or not, there will be things coming in the future that will. That will be made possible in part because of keeping the code lean and mean. Also, some of these things take time, they involve pure research first - for example, our planned implementation of caustics (planned, not promised ;) ). Our plan is to make it easier, and faster, than what we are used to for caustics. Whether that could have been done a year ago is open to question, it took research, and testing, to see if this was even feasible. So, sometimes the overnight revolution to rendering takes a while to happen :)

Thanks tom. Just as an appendix to my two cents above im not saying what you guys have achieved thus far isnt awesome and game changing and im certain everyone finds use in different areas of the software otherwise the features wouldnt be there. I think the issue arises when you have this poll here that is massively user centric as you guys have always been, and there ends up being features included in the newest releases that werent on the poll and only a few have use for vs the larger and obviously harder to implement features. That seems to be the disconnect if you break it down. Again thanks for everything you guys have done so far! I dont want to sound ungrateful for the sheer amount of user interaction yourself and all the Corona team do. Its really valuable to have this level of contact. If only more companies were like this . Looking at you Autodesk.

No ingratitude perceived! Just wanted to give a pretty detailed answer to some of the points, and they were from a mix of posts and people. Even that fairly long answer isn't the full story; as noted, the range of factors that have to be taken into consideration in deciding what is being worked on next is very complex, and we always do our best to try and balance between all of that. Requested features is indeed a big part of it, but there's a whole mix of other stuff too - and we'll keep doing the best we can, and see where we can do better, and of course always be making Corona better as we go :)

Post by: Ondra on 2019-01-07, 17:04:22
Thank you Tom for long answer. I wanted to answer few times, but I every time I deleted my post because it was too impolite.

I will just say that everyone is entitled to their opinion. However you must realize, that even features "that should have been already done" or "are not implemented entirely from scratch" or "are just optimizations that I expect to get for free with every release" nonetheless still take time to develop, test, and debug. If you decide that something adds 0 value just because it falls to one of these categories, then that is your opinion and you are entitled to it (and I am entitled to not take it into account).

This is why we are forcing you to choose between optimizations and new features - optimizing something takes time, same as implementing something new. This is just a fact of life. Also lot of decisions we take are based on feedback outside of forum. For example during the last tour in London, I got almost no requests for faster rendering, but most people want better performance in huge scenes (RAM, startup and shutdown times), so that is going to be optimization focus in v4. Only fraction of our users post here. In fact, many of the biggest powerusers simply do not have time to post here.

Thank you Tom for long answer. I wanted to answer few times, but I every time I deleted my post because it was too impolite.

I will just say that everyone is entitled to their opinion. However you must realize, that even features "that should have been already done" or "are not implemented entirely from scratch" or "are just optimizations that I expect to get for free with every release" nonetheless still take time to develop, test, and debug. If you decide that something adds 0 value just because it falls to one of these categories, then that is your opinion and you are entitled to it (and I am entitled to not take it into account).

Just on the 'expected with every release' perhaps my wording was off. I meant its something that really doesnt need voting for because realistically its something im sure you and we all want. I didnt mean for it to sound like we didnt find it useful. Just it doesnt seem to be that useful in terms of a voting option. Who doesnt want it faster? :)
Again the work you, Ondra, and your team has done has for me made it much more fun to work in 3d again and i cant thank you guys enough. Ive converted so many people to corona over the years and im not likely going to stop!

Ondra, I think there's a miscommunication and a disconnect between the developers and the users.

I believe the users are questioning the usefulness of the developement of features in versions 2 and 3, and they are suggesting that the efforts of your team didn't go to the right place, and that as a result some of the really useful features were released incomplete.

Being transparent:

Corona 2:
1-PhoenixFD (Did the user base really ask for this?)
2- OpenVDB and CoronaVolumeGrid (Did the user base really ask for this?)(I can't use it without a VDB file)
3-3D Volume Materials (Not usable as global atmospherics in my opinion. I can expand if necessary)
4-Compatibility with vray (Did the user base really ask for this?)
5-Bokeh, Center bias and vignetting (nice to have, did the user base really ask for this?)
6-Material Library (Did the user base really ask for this?)
7-Corona toolbar (I can't imagine this being a big task, with all due respect)

Corona 3:
1-IR feedback improvements (Honestly don't notice a difference)
2-Nvidia denoising (excellent!)
3-Improved displacement (as others mentioned it's not ideal the way it works. In the video it's shown as if it works amazing, but it was used in a particularly easy case -large separation between stones, and surface detail. In real archviz cases at least I didn't get good results with setting at 3, 4 or 5 pixels)
4-Multimap (What's wrong with the free multitexture map?)
5-New united lister (How long did this take really? It seems to be incomplete too, no cameras or proxies for example)

Edit: And most of all, users are voicing their opinion so Corona focuses efforts in the future
Edit 2: OR to make sure they understand where corona wants to go so they can make an informed desicion to whether they stay with corona or not and what hardware they need to get if they decide not to.

In my opinion less is more.

yes, it is something everyone wants... but it still takes time to implement, so the question, how much exactly do you want it? Would you be happy with speed improvements at cost of dropping 1 potential big feature? 2 big features? 3? ;) Same with memory optimizations...
Title: Re: The most wanted feature?
Post by: Jpjapers on 2019-01-07, 19:47:05
Personally I'd like to see standards like aces and pbr implemented sooner rather than later but that's just my opinion as you said. But with those being high on the poll I'd guess alot of others feel the same too

Edit: I completely understand it takes time to optimise and I hope you and Tom and the rest of the team in turn aren't seeing this as any sort of attack on your skills or anything. For me its more about understanding the teams priorities because currently there is no reliable indicator.

Post by: bluebox on 2019-01-07, 19:53:12
I always thought that speed comes (partially) also with leaner code. Personally Corona is fast enough for me. On the other hand I'm under an impression that there is some kind of consensus that there is a lot of room for improvement on the field of tone mapping etc.

Apart from memory optimizations is this being considered as "the big feature" for the upcoming release ?
Title: Re: The most wanted feature?
Post by: lupaz on 2019-01-07, 20:05:44
Of course everyone will say yes to the question "do you want to render faster?"
But how fast can Corona get by just improving the code? I can't imagine the difference being significant to match a GPU render engine and a couple of GPUs.
I'd think Corona is at the mercy of CPU development, and I think the user base knows this and it's ok with it.

And I'd say the same with RAM. Get more RAM if you need it.
But we can't get a better BRDF elsewhere and plug it in to Corona.

Allright, I will try to explain myseft.

First of all, I am pretty sure nobody wanted to hurt or offend you guys, including myself as well.
I had/have an opinion what I've shared. It looks like for the majority of your customers different things in the engine are (more) important. Noted.

Sorry, I am not going to play with the quote feature I just want to reflect on some things.

...there was an opinion here that the NVIDIA Denoiser was really nothing major, just something generic.

It was me ofcourse and after all I apologize a little bit about that. It wasn't completely nice to say like that and I didn't exactly meant like that. As I said I like that feature, its a game changer, thats why I'll renew my subsciption as well. I was dissapointed a little bit, becuse I expected something more besides that as well. It's not needed to tell me again, I understand.

You can't please all of the people all of the time, as the saying goes :)

It's true, and true. We only would like to see a little bit more exact things, or more accurate things in the development roadmap it that is possible. There was a missunderstanding here, (some) people (including me) took the development roadmap more seriously than we should have had to. Now we know those are not exact things, just planned possible things.

but I every time I deleted my post because it was too impolite.

If I was impolite I apologize again. We are just talking not arguing. Nobody accuse anybody with anything.

most people want better performance in huge scenes (RAM, startup and shutdown times)

I would love to see/have those. We work on large scenes as well.

Only fraction of our users post here. In fact, many of the biggest powerusers simply do not have time to post here.

OK, It's a little bit hard to understand what you meant by that. I mean, I understand a little bit, but let me not reflect on that.




Corona is definitely a large company now. I am not talking about the number of people who work there I am talking about how they see the world businesswise.
You know what, I understand that one as well. they want to keep an eye on the companies future, I would do the same what they did/do.

Everybody needs to understand that, it's not the same company what it was a couple of years ago. I am not saying it becomes better or worst, it just becomes a real company.
The merging with Chaos Group, the focusing more on money what big sharks want made some people dissapointed. Nobody blames you guys. Every company has to make that decision who wants to grow above a certain level.

We love Corona, we love the family, some people just started to feel that the other family members not listening with full focus anymore. 4-5 (who knows) years ago every opinion was important but it can't be like that anymore because there are thousands of opinions out there. Understood.

We are archviz guys, you need to understand that. Ofcourse we ask for those things what we would need or love to see in the next releases. If the company focusing more on different areas, (maybe because they want to break into other parts of the industry as well) we understand that as well, companywise, but we not celebreate that.

I didn't even want to write this comment, not because I am dissapointed or mad with anybody. I didn't want to do it because I think I understand your point. I am not a company owner ofcourse but I've managed to live the past 40 years on this world and I try to keep my eyes and my mind open as much as I can. That doesn't mean I am right or wrong. Some people will think I am right (in a few things) the others will think I am the stupidest person who ever lived. That is completely fine.

As an end note:
We are all looking forward to the next releases. You guys do your best, we will try to do the same as well.

I forgot to mention something and I think thats the real point of this whole thing.
We are artist, we have different needs. Large companies (those are the important clients, thats understandable, I buy 1 licence, they buy 1000 licences) want more speed, less RAM usage. The quality of the corona renders are already superb, ofcourse they want to speed up their renders to make money more quicker with a less expensive render farm.

We - artists - on the other side prefer those "special" things (as well), what makes that f* vase on that table more photorealistic. :)

few notes:

since I see chaos group thrown here or there: in the 1.5 years we are together we never were ordered to implement or not implement something in Corona. All decisions were ultimately our own.

speed: it is true that for new renderer/renderer with not many features, lot of speed comes form the "lean-ness". But as the renderer gets complex and supports many features, that is no longer true and you have to invest lot of time to improve/keep the speed.

Those corporate fatcats that we cater ;) to are studios of 6 to 15 people. We were in contact with them since the beginning and they are still archviz users. I brough it up just as illustration that there are other sources of feedback, but this does not mean we are now doing exclusively that. In fact, we want to attempt (cannot promise anything) most of the features mentioned here in v4.

cpus being dead: 2 years ago if you were building a machine, you would buy a 4core i7 with maximum being 8. Today, you can build 12core threadripper for the same money, with options to scale up to 32core in single affordable desktop CPU. I am not saying we will get 128 core CPUs in next 2 years... but say what you want, CPUs were anything but dead in the last 2 years.

BTW: Even majority of the forum IMHO agrees that the new features are useful, since when I remove something from the most wanted list here in thread as done, most times it was in the TOP3 choices. Too bad I dont have historical poll data.

few notes:

Thank you for your answer Ondra.

Offtopic more or less

Talking about CPUs/GPUs is a pretty interesting thing. I am planning to push my career towards freelancing because of different reasons. It is a longer term plan, lets say in a year.

Ofcourse money (I mean the amount of money what I actually have or what I would like to spend on start later) is an important aspect. I am planning to buy a powerful workstation in the next couple of months (what I would be able to use as a render machine as well) and I am confused a little bit.

It looks like the only smart solution atm are those Threadrippers with 24/32 cores.

I worked in three different offices in the past 6 years. In all of them they used Vray when I started and especially 5-6 years ago (be honest) that was the right decision. In 2 of the 3 offices we were able to persuade our boss(es) to switch to Corona from Vray.

In my opinion the end result of Corona is nicer, especially the light distribution. The rendering speed of Corona has been always an issue (in my actual office we use 24 (a little bit older, but still decent dual xeons as a farm, the approx speed of one of them (with 2 xeons) is like a modern 12 core i9, so lets say 24 of those). Even with those machines (in distributed, split render) sometimes we have crazy render times (4 hours in 4-5k but most of our scenes are heavy).
Thats why I said it depends where we look the case from. As an artist, I prefer more photrealism as a wannabe freelancer I prefer speed and less RAM usage. I am fighting inside with myself. :)
If I would be able to make decisions which way Corona would follow, according to my brain I would choose speed, according to my heart I would choose more photorealism.

Personally I prefer to keep the noise level of my renders pretty low, I use 2% what can be an overkill to some people. I like the real time denoiser but I don't like to use the denoiser in the final render (that will change no later than on that day when I will need to provide the necessary computer power for the renders :)) I know, probably its a huge mistake to use 2% of noise without any denoising at the end but I like to keep the end result of my renders as less affected as possible.

From this aspect I think some kind of Hybrid solution is important. Let's say if it would be possible to speed up the scene parsing process with a GPU or the displacement calculation, that would be a big plus. To be honest I know nothing about computer programming I have never been interested in that thing. I have no idea what can be possible and what is not.

According to those pretty expensive CPUs (lets talk about gaming cards because those are the things what most mortal can afford) even a powerful GPU (2080Ti) is cheap.

CPU wise, what is your opinion, which would be better as a start? To buy a more powerful workstation (let's say the the 32 core AMD) and buy separate render machines later or buy a less powerful workstation (let's say an 8-12 core intel) and buy separate render machine(s) the same time as well?

I think, these days, when GPUs are more and more powerful for less and less money you can't avoid (at least you have to think about it as a future plan) to go towards some kind of hybrid solution. If you can archive 50% more speed with the cost of €5000 CPUs or the same with €2500 GPUs, probably nobody would say: don't do it.

What is your opinion about those things above?

Another interesting thing is (I am not going to ask your opinion about that :)), which render engine to chose. Atm, Vray (especially according to speed and reliability in distributed) is more safe, more predictible. But Corona, according to quality, "friendlyness" and my heart is a better solution. If you make money with it and not "just" your boss (if he reads this, I love him ofcourse), speed is important, or more than important and "safety" as well.

Post by: sirio76 on 2019-01-08, 14:01:09

I think, these days, when GPUs are more and more powerful for less and less money

To be honest its quite the opposite, GPU speed increment are becoming marginal and price are going up. Once you forget about all the RTX mumbo jumbo(no renderer are able to utilize RT core right now and even when it will be possible we should see the real benefits) as a matter of facts a 2080Ti offers barely 30% more render power when used in GPU renderer compared to previous generation(1080Ti is more than two years old so it's just 15% a year) but costs almost twice as much.
I totally agree with Ondra, CPU renderer are here to stay(BTW people were telling CPUs were dead since much longer than 2 years).
My 2 cents :)

Post by: Ondra on 2019-01-08, 14:27:37
BTW people were telling CPUs were dead since much longer than 2 years
small note: CPUs were quite "dead" (or in non-internet-discussion words, their development was slow  and performance gains minimal) approx between ~Haswell and Ryzen. All that thankfully changed with a bit of competition from AMD
 
Title: Re: The most wanted feature?
Post by: sirio76 on 2019-01-08, 14:38:26
That's true but as noted it was only because of the lack of competition, not because the technology was dead itself. And that's why it's important to support AMD on the GPU side too, unless you don't strictly need CUDA they offer competitive cards for less money.

You can use the global volume material slot to achieve this but you will still get volumetric shadows unlike vray aerial perspective.

Thanks friend I know the corona volume mtl but I like the new aerial perspective of V-Ray because the effect calculate automatically  based on height and distance value, so for me this is much more real than the manual config values that I could to do with volume material, so the volume mtl is alredy great for the use on volumetric effects and other things ;)

I don't know if someone mentioned these before, but I'd like to see:

- flow maps

- node material editor:
    - grouping multiple nodes (like in unreal engine 4 fro example)
    - points to manipulate the way of the wires (for better organization)

- vector displacement

Post by: Dalton Watts on 2019-06-20, 17:17:56
As hybrid rendering takes the lead will it ever be considered given the developer's principle of Corona being a CPU only renderer? I suppose it is the most challenging "feature"? If so, would it work like v-ray in the sense that we have to first select GPU renderer and then select CPU to help the GPU or would it work the other way around?

Love to see a wood shader one day!

It doesn't make much sense. A renderer renders. Maybe you meant a wood procedural noise? There is some that can be implemented, but otherwise you will have to use texture softwares or libraries for that.

I agree a corona noise would be useful. Especially for conversions from fstorm etc.

I believe he ment a custom BSDF shader. I remember seeing a discussion on that sopic somewhere but don't recall where exactly.

Yeah, there are 3 approaches to "Wood shader", it's not nonsense.

1). Procedural noise that resembles wood but otherwise does nothing special shading wise. You can get this for example in OSL in Max 2019+. Not interesting at all.
2). Procedural noise that resembles wood but actually creates multidirectional anisotrophy based on the produced wood grain. Someone told me this existed in Mental Ray as 3rd party addition ?

3). This would be dream and I don't know how exactly it would work (it would require modification or new BRDF). Shader that could produce multidirectional anisotrophy from any bitmap, so that we don't have to use stupid looking procedural generated wood (I have never...never fucking ever, seen even slightly good looking procedural wood, it's all shit).

Even fabrics have multidirectional anisotrophy that can't be produced right now, but that's much simpler two-directional (opposite directions usually, like Silk fabric), but wood have super unique anisotrophy that no other material have. Why do you think all the wood shaders look like crap if it's natural wood :- ) ? We can only render glossy wood with coating/varnish/etc.. but good luck rendering natural rough planks like Dinesen Fir to actually look like Dinesen Fir. No way, at all.

You can try to simulate the effect with combination of micro displacement and SSS (Wood has pretty noticeable SSS) but it's not exactly it.
(Similarly, you can produce bidirectional anisotrophy of Silk fabric by using F-Storm GeoPattern instead of texture surface)

The geopattern fabrics s**t all over every other renderers approach to microdetail in my opinion. Theres absolutely nothing else that works as welland i really with we had it in corona or at least a third party plugin for max that achieved the same thing.

I've been spoiled by how well FStorm handles bump mapping, and bitmap filtering/sharpness in general. Perfect example is how you can create an anisotropic metal just by using bump maps (and it doesn't break at different resolutions/zoom levels).

Even with 8K wood floor bitmaps for example, for some reason Corona just can't get as sharp without the material turning to a blur at a slight distance, while FStorm retains full detail. I've done a 1:1 comparison and the difference is night and day.

Procedural wood textures (2015) by Albert J. Liu, Stephen R. Marschner, Victoria E. Dye

Quote
Existing bidirectional reflectance distribution function (BRDF) models are capable of capturing the distinctive highlights produced by the fibrous nature of wood. However, capturing parameter textures for even a single specimen remains a laborious process requiring specialized equipment. In this paper we take a procedural approach to generating parameters for the wood BSDF. We characterize the elements of trees that are important for the appearance of wood, discuss techniques appropriate for representing those features, and present a complete procedural wood shader capable of reproducing the growth patterns responsible for the distinctive appearance of highly prized ``figured'' wood. Our procedural wood shader is random-access, 3D, modular, and is fast enough to generate a preview for design.

Simulating the structure and texture of solid wood (2016) by Albert Julius Liu, Zhao Dong, Miloš Hašan, Steve Marschner

Quote
Wood is an important decorative material prized for its unique appearance. It is commonly rendered using artistically authored 2D color and bump textures, which reproduces color patterns on flat surfaces well. But the dramatic anisotropic specular figure caused by wood fibers, common in curly maple and other species, is harder to achieve. While suitable BRDF models exist, the texture parameter maps for these wood BRDFs are difficult to author---good results have been shown with elaborate measurements for small flat samples, but these models are not much used in practice. Furthermore, mapping 2D image textures onto 3D objects leads to distortion and inconsistencies. Procedural volumetric textures solve these geometric problems, but existing methods produce much lower quality than image textures. This paper aims to bring the best of all these techniques together: we present a comprehensive volumetric simulation of wood appearance, including growth rings, color variation, pores, rays, and growth distortions. The fiber directions required for anisotropic specular figure follow naturally from the distortions. Our results rival the quality of textures based on photographs, but with the consistency and convenience of a volumetric model. Our model is modular, with components that are intuitive to control, fast to compute, and require minimal storage.

Final thought
Yes, microsurface details, scratches, glints, distorted/directed anisotropy, spectrality ;) ... all this will sooner or later become inadmissible in archvis, product vis, advertising in general. It's the road to full CGI realism. For example, check the details on the latest Toy Story 4 :)


The finer the displays get (bigger, more precise), the greater the need for details.

BTW, anyone knows on what studies/papers is Corona's hair based on? Marschner's?

I am really super interested in this. Bump strength and texture filtering are greatly important and annoying to me. I've been using the 'Bicubic' filter in CoronaBitmap lately and BumpConverted to circumvent these issues but I don't think I am very satisfied.
Things still look very flat tome.

I would be very grateful, imho this is super important because it's such a basic and I feel we are still in middle ages with it (in general).

Yup, all this ! Now that we have almost all features (Hair&Volumes shading, Caustics,..) and they are improving the displacement as we speak it's time to bring the focus down to shading.

-The PBR shader and subsequently improve all aspects of it, including BRDF. I can't stand Lambert diffuse shading to start with. Fabric sheen, coating.. then move onto glints, directed anisotropy, etc..

Most of production will move to real-time soon if it didn't already so the only strong point of raytracing will remain absolute photorealism. 

Though I could still use better tonemapping...

Agreed on all points. Would love some more complexity to the corona material like complex fresnel siger style. Clearcoat for definite and geopattern for fabrics tbh. Im so jealous of the fabrics in fstorm.

Switching to a GPU renderer doesnt instantly mean faster rendering. AFAIK gpu rendering would require Corona Core to be completely rewritten. Im sure Ondra said something to that effect in this thread.

It's more accurate and natural compare to corona, what always or too sharp or too blur what will similar to bloom, also it have dirty lens effect, obstacle map etc. It's also have other features like color fringe.
you can see  examples on site

As Juraj said Vray also have dirty map now

Thank you! I didn't know that motion blur working with Phoenix FX. Bud anyway we don't have foam and i think, i mean that we need even more some mesher for all/some kinds of particles. For exemple i working in realflow, it has own meshar, but it is slow and terrible.

Your render already has AO via GI. Adding AO afterwards isnt necessary unless you want a less realistic output.

Also, maybe it will be as new good idea about the sky. I saw some model of sky with clouds for example. Also, maybe it is time to add some model without green colors, when you make it bright. It is always difficult to remove this color from the bright sky.

I'd like to be able to use Corona sun+sky to set up the lighting exactly where it needs to be and be able to get some clouds from the HDRI map in reflections. In its current state, there are fireflies everywhere. I know you guys consider it from quite a while and that it's not an easy fix but you keep adding features and the more you wait, the more complex it will become to solve. It's time now, please! That's such an important feature for me that I actually consider switching back to Vray. That and masks in reflections/refractions are the two main blockers in my day to day work.

Multiplayer in portals.

In some situations, for exemple when you looking through the window, you can see burn behind the window of all objects. For exemple too, in FStorm no need to make our objects outside the window (trees, cars street, etc) darker and less reflective, you can do it with just multiplayer in portal material. And it will be great if there will be color of lighting too.

Eliminating that annoying noise that remains on bumps & rounded edges, when using the native "Corona High quality" denoiser.

I already wrote a couple of times that this less denoising on bumps for the sake of "preserving more details" is total nonsense in a real daily workflow, since images literally fall apart in noisy and less noisy areas.
But I see it got ignored until now.

Thanks God, you guys built in the CPU AI denoiser... otherwise I would have dumped corona long ago.

That's not the point here, I'd like to be able to adjust the lighting the way I need it and not try dozen of HDRIs to find the right sun Azimut. Corona sun is very convenient for animations when you have to change the lighting between multiple shots.

It is new material. It is not THAT fundamentally different from current Corona Mtl, you can think about it as changing the way controls are preserved and adding multiple tweaks at one time (roughness/glossiness switch, new diffuse BRDF, sheen, ...)

But if you have a loader slot on the corona camera it would be SO much better option, no?
You could send works to backburner just selection your camera and boom, there you have your render with your custom lightmix settings for that specific camera.

cool idea.
for example, I render studio light. I have a one product and I need to do 8 different angles to it.

I came to the fact that I do not create 8 different scene files. I create one scene. and doing instances of the object and the whole world, lights and cameras. I delimit the scenes in black boxes. so that the light does not interfere with each other. and I’m doing multilight in the Instance mode. all is cool. but if I should change the source intensity. it should be made a copy, not an instance. Your idea corrects this.

We have our own plugin that makes what pulze do (not a copy, we had the idea a time back :) but pulze wont do lightmix per camera right?

Not completely straightforward right now, but you can enable saving passes per camera setup in it.

1. Fstorm introduced a new feature. a texture tiling randomiser. it takes a texture and randomises its locations and rotations over geometry while blending the edges in a way that removes seams, it effectively makes it possible to use, for example, a 2x2 meters textures over a surface that is 100x100 meters or more with no visible tiling which is extremely useful in Archviz especially for glossiness textures.

2. Fstorm has a noise map that is so natural in its structure it might be the best out there, if you compare the structure of that noise to real life objects you realise it's really smart and emulates a wide range of medium and small scale noise that happens naturally in paper plastics leather stone, you name it. maybe it's time to have a dedicated corona noise map.

I posted this elsewhere but here it is again I think the first feature is especially useful.

What exactly is meant by "DSLR style tone mapping"?

Tone mapping that works like an actual DSLR camera's response (which can't be faked with LUT's), specifically in terms of dynamic range (no ugly murky greys), pleasant highlights/burnouts, natural colour shift in relation to exposure e.t.c.

At the moment Corona's tone mapping is very much in the realm of "CGI". Compare it to that of Fstorm and the difference becomes immediately noticeable. It's not a case of GI/light algorithms, it's purely how the the final image is tonally mapped using some sort of transform matrix to produce a pleasant and convincing "real" image.

It is the single biggest factor imo to producing a convincing image. You can have 100% spot on materials, lighting and modelling but if the tone mapping puts a 2005 Mental Ray sheen over it, it will never look great.

For some examples of great tone mapping take a look at: https://www.behance.net/Johannes_L You'll notice just how balanced and "real" the images are. No ugly black crush, no washed out grey mids, no overly burnt cellphone style highlights, no neon colours under burnouts.

There are multiple things to say here. Fstorm is not the magic secret trick tho. Johannes uses custom LUTs to reach is look. Some of the renders are retouched in post.
That said, Fstorm is using ACES workflow which make a hudge difference in color gradation. That's what I observed from my tests in Vray. It just feels more natural. But it also comes with render penalty. If you want to do it the right way, you'd better render in ACEScg colorspace. So you need to convert your textures in that colorspace. If you do that at rendertime, it will bring some overhead. What's more, you have to implement color management ( maya style is great) to di it properly too.
So that's not an easy topic, devs needs to think hard about this.

agreed to all of it. still Fstorm does not get you 100% real results unless you do some of your own post like Johannes does. another example is Peter Guthrie's work, and the greatest of all Bertrand Benoit.

the surprising thing is that you couldn't find that info anywhere, how to get the realistic look, every artist out there who got it protects that knowledge dearly. I am able to get that final result with post in corona VFB and photoshop but it came with experience rather than actual knowledge or "theoretical" background. and Fstorm seems to be always one step, as a raw render, ahead of any post I do AND any post of any corona image I've seen with the exception of Bertrand Benoit perhaps.

point taken and I do agree. however, when I first started many years ago, no tutorial out there would mention tone mapping. they all, or at least the ones I took a look at, skipped it. it's not only about the tone mapping, when I watch a tutorial I could see skipping here and there, and it's about many other things, and I do know they skip stuff because I know that stuff.

but yes it's about experience and you could notice that if you tell somebody all you know about CGI when they apply it it doesn't look right, because experience ties all the knowledge together.

all that said, tone mapping and how linear data is transformed into visual data that looks good to the human eye is knowledge you have to be taught or learn bits and pieces with experience.

"Tonemapping" has also become almost a buzzword for many processes that should more correctly just fall under "post-production".
There are even people who have their own magic tonemapping. This is total nonsense, don't fall for it.

Back in day no one talked about it because everyone used Reinhard in Vray which is the same btw as right now in Corona, or linear and recreated similar curve in 32bit editor (I personally loved doing this in MagicBullet when it was still available as PS plugin).

Artists aren't really hiding any of this knowledge, most people aren't even aware of it being a thing. Actual issue is that tonemapping just isn't popular concept for CGI developers for some reason, it was topic almost single-handedly popularized by one guy, John Habble, the guy behind filmic mapping. But since he's now with Ubisoft I think (or EA?), he doesn't really publish more stuff or research on this further.

I suspect the reason could be that it's based purely on aesthetics, it's not much of science thing unless you consider the sole original purpose of showing widest dynamic range at same time (remember that horrible photography era 2000-2005?).
What FStorm does is literally just better tweaked single-curve, the color transforms are almost secondary to it.

What we can do, is just constantly vote for it, and bring it up in forum, over and over :- ). Like PBR! Hell yeah, let's get voting!

Corona Team - please!  Make a cheap aerial perspective. Volume material - as it is now - cannot be used in large scenes. I don't care about the godrays and proper light simulations. Color and contrast change based on distance will do. And small checkbox: don't affect the background, as hdri's have their own, embedded aerial perspective.

tone mapping and post production became synonyms out of ignorance that's all. post production is taste, everyone does it different, more or less contrast, green all over like the matrix or some kind of nonsense. except for contrast that is considered post production for some reason, lifting the shadow too. that is the popular understanding of the terms but it is not accurate at all. we need a new term I swear! but tone-mapping is theory and application and an attempt to simulate the first few steps the brain does to light linear data. the fact that CGI developers are oblivious to tone-mapping is a huge oversight. Camera developers/manufacturers have been perfecting their methods for decades hampered only by the lack of development of sensors capable of taking in the full dynamic range close enough to the capability of the human eye, and a Reinhard tone-mapping method that is close to the brain's ability as is a bicycle to a space shuttle.

I know it's called photorealism, I wonder why the community glues itself to that term when we got a far superior flexibility in a simulated world where we can leave photography in the dust and actually work on how the brain analyses visual data.

artists do have their secrets of the craft. every craft on earth has that. it's like this. if I were to ask you to send the full folder of a project you've done. what would you delete? what would you hide? those are your secrets of your crafts. artists are no angels don't fall for it.

Parallax Bump - it looks great! With the help of this function, we can greatly increase the detail of our work, for the exterior it will simply be an irreplaceable function. Soil, water, paving stones, sand, snow, much more - all this can get amazing detail. Now it is already being implemented in FShtorm.
FShtorm has a small development team, but they have a lot of good creative ideas.

We really need a new tone mapping in our Corona, OCIO / Aces support - I think this is the most important thing that should be implemented in the next version of Corona or in updating the version of Corona 5

non of the above. no PBR. we're getting V-ray's features, they make rendering faster but they hit the quality hard. remember that V-ray-no-contact-shadows look we all hated I believe that's coming back in corona. I might be overreacting, but corona is getting closer to V-ray and slumping to its level instead of V-ray improving to corona's level. corona had that soft look to its GI that distinguished it from other engines.

My interest in seeing the new vray light cache brought to Corona would rank somewhere between ’zero’ to ‘please don’t do it.’  Meanwhile a new pbr shader would be awesome and something people have been asking for forever.  I realize I only speak for myself but this seems like a very strange decision.
Title: Re: The most wanted feature?
Post by: JViz on 2020-02-28, 20:22:13
it's not a strange decision really, it might be because technically they cannot do the PBR material within the time-frame of version 6 release, simply not having the research and coding capability for now. or it might be a business decision but this is where conspiracy theories emerge lol they want to merge the two renderers -corona and vray, and this move might get them closer to that goal. in either case I'd hate to see corona go down the drain, we had quite the ride, but I'm at the ready to shift to another renderer in 5 minutes lol.

Post by: danio1011 on 2020-02-28, 22:10:34
Yes, all fair points.  Although one can assume that incorporating the new light cache takes some coding resources, but maybe much less.  When I see ‘incorporating VRay’s GPU based denoiser’ on Trello I’m going to cry :)

I know the team works their asses off and you guys have had a particularly rough time recently and it's great that Corona is releasing versions more frequently. Incremental improvements are always welcome but id have hoped that v6 might have brought something from this poll.

Changes on the roadmap are because we had a hackathon with chaosgroup guys and found several of their technologies useful - new cache that is more stable in animations, adaptive dome light sampling, and bloom&glare effect that is better looking, more customizable, and also significantly faster. The sky model is result of independent research.

The only downside is that we will probably not make the PBR material on time for v6 release. I am still not expecting the PBR material to cause any sort of revolution, Corona material is 90% there. I am worried that when we finally release it, people will still be disappointed, because it will not make their images magically better.

The only downside is that we will probably not make the PBR material on time for v6 release. I am still not expecting the PBR material to cause any sort of revolution, Corona material is 90% there. I am worried that when we finally release it, people will still be disappointed, because it will not make their images magically better.

I will not address the ridiculous conspiracy vray theories. If there is somebody not burned out by dealing with entitled fanboys, please do it for me ;).

If its the case that the PBR material isnt what some people think it is then perhaps its worth mentioning what it actually could be to calm the hype or misunderstanding around it? As i understand it, it would just make working with other PBR software a little more convenient. Im not personally expecting any changes in a final image, just a more streamlined pipeline and possibly clearcoat/sheen settings but thats about it. Slightly nicer interoperatbility with Unreal Engine could also be a nice to have ;) .

Looking forward to seeing the sky model in the dailies!

@JViz, i'm pretty sure that there some misinterpretation took place. I don't think that Corona team would want to silence its users. Everyone is free to express their opinion and concerns and it would be nice if we could stay respectful to each other.

Ondra, re the PBR material update - will it include the new diffuse shading model? There were a couple of images posted in another thread showing Arnold's Lambertian shading implementation that looked light years better on rough/diffuse surfaces. Would be great if we could get some controls for sheen/coating and whatever controls the falloff effect on fabrics (via realism and not falloff fakes).

Also any word on improving bump mapping (similar to how you can achieve realistic super fine anistropy in Fstorm just through bump mapping and it's not view/zoom dependant). I don't know if this is linked to improving the material model or a general engine improvement.

We will investigate the diffuse models when doing the PBR, as well as other changes, this is why this feature is currently ranked as the most development-intensive one in our tracker. I cannot tell in advance how the end result will look like and what models it will use.

agreed, it's very hard to do. a lot of research needs to be done. few in the industry have a good understanding of how this works or can be implemented. Andrey Kozlov implemented diffuse roughness very early to Fstorm, but he might be using a simplified recipe or something, or he's just the Einstein of render engines. cheers Ondra, you can do it too! *don't ban me :D :D

In my opinion you're right. a PBR material would make things slightly easier to work with, for example, substance. But with the current material I can still do it. It takes a bit longer.
However, it is the standard and IMHO it has to be done sooner or later.

I really don't understand why a new cache map that is more stable in animations. As far as I know your user base does mostly still images. If I needed to do animations I'd use vray or a GPU based render engine. I wouldn't use Corona at all even with a new cache. Who knows. It may blow our minds off though.
EDIT: I just realized there's the C4D user base :)

Nice to see this!: "Comes with fog/aerial perspective" in the new sky model.
But aren't most of us using HDRI nowadays? Is the aerial perspective compatible with HDRI?

Thanks.

Just a quick note on conspiracy theories (I am not too burned out ;) ) - it was expected, and part of the reason for the merger, that one team would borrow code from the other. Why re-invent the wheel? When one team has done the research, read the white papers, done some feasibility checks and tests, written some code, optimized the code, got it production ready - why would the other team not take advantage of that? It may even mean that the work involved is "only" the outside part of getting that code hooked into the other engine (of course sometimes it's more involved than that, and sometimes even that is non-trivial - but, it still means skipping the research, reading, feasibility investigations, and so on, which is always a chunk of time saved).

So if there is something that is good, has been proven to work, and it can be integrated faster than normal, we will take advantage of that. This goes both ways, V-Ray features making their way into Corona, and Corona features making their way into V-Ray. In no situation does that mean the engines are combining, becoming one, one is being dropped for the other, and so on (after all, each team comes up with new and innovative solutions, often on their own - this happens BECAUSE there are two engines, even though in the end both engines may benefit).

look tough guy, a major feature got shot down, we want an explanation or we are storming area bs bs something. seriously though, it's a big feature what did you expect? and nothing out of the ordinary was said above.
two options:
a technical difficulty
OR
a business decision

very reasonable actually. don't blow things out of proportions. just don't be the censorship, it's vastly unpopular these days.

This.
Each time people start asking questions there ALWAYS comes someone who's not even part of the Corona team and advocates on their behalf like he knew exactly what and when the team was doing and reasoning behind teams decisions. Or suggests that you are being disgracefull to the team because you dare to ask questions about the product you pay for.

Questions asked to Corona team should be answered by Corona team members. Unfortunately many topics in feature request section (not only here) are left with no answer at all IMHO because it works like this:
A: "hey team, what about feature X, that would work like this and that"
B (user, not Corona member): "why dou you need this, I think that it is not necessery and you can always workaround this"
...
Same goes to even slightest critique of the development subjects.

I still remember the days when Ondra himself talked to people on the forums about new features and introduced them overnight.
I also understand that things are now way more complex and this is not doable anymore.
However recently in daily build section there was a discussion when dedicated people posted examples concerning some hints about research being done elswhere on the PBR shader, diffuse model, some papers on the subject etc. only to be removed by moderators as pointless discussion. Rly ? When people try and be helpfull in any way ?

And the initial roadmap is not being followed once again and top three features from the poll are not being developed.
What is the reason behind this topic then ? This supposed to be a major version with new features and yup, there are many. Just not those that majority of the people want aparently.
Development of V6 will take over 6 months, then standard period of 3mo code cleanup version and there you have it. 9/10mo development cycle that introduces none of the most wanted (according to the poll) features ? Quite possible.

Was really hoping for that new shader with lambertian controlls, sheen etc. as well as tone mapping rework. So disappointed again.

There is no problem merging features from two different engines, I only worry about the fact that this merging comes at the expense of adding new most wanted features such as pbr shader, new tonemapping and geopattern support, projection mapping and parallax bump. maybe it’s worth a bit to increase the development cycle so that you do not suffer from such a shortage of time? I’ll be happy to wait a few months before the release of the new version of corona, if after that we will get another well-thought out feature as it was with caustics. I love corona render for doing everything in its own "corona-way" and I hope you will please us with new ideas, good luck in your difficult work!

As a note on the roadmap, as the roadmap clearly says, it is not WHAT will happen, but what we are planning. And as with everything in life, plans change, and when that happens, we update the roadmap. This is why it's important to keep a watch on it, and not just glance at it when 5 comes out to see what 6 will have, as what 6 will have will change (e.g. we start development and find it will take longer than expected; we find something not on the roadmap that can be quickly integrated so we add it; and so on).

Just that I've seen some people basically complain that the roadmap changes, which is a misunderstanding on what the roadmap is.

B (user, not Corona member): "why dou you need this, I think that it is not necessery and you can always workaround this"

If you don't like it that way, you can always submit a feature request using the helpdesk without public involvement. But if there would not be such, we would already have about 100 checkboxes scattered anywhere to suit every request made. Those requests often end in a "oh, I didn't know that, tnx" or "wow, already there" because "non Corona members" took their time to help and offer alternatives which work perfectly for them and thus maybe also for the requester. And keep in mind that 1. feedback and 2. discussion are valuable resources for development in general.


Good Luck

The posts were not removed, just moved: https://forum.corona-renderer.com/index.php?topic=27739.0
This was because often in the "daily discussion" thread users are reporting issues they face, and that could easily get buried in the PBR discussion.

Don't shoot yourself in the foot again, you just did twice don't make them thrice.
One: reading your argument about engines borrowing features from each other, (read it guys) they'll become, eventually, indistinguishable, ie become one. I know you'll say they develope separately, but so far we've seen features that set them apart... cancelled.

Two: are you redefining what a roadmap is? A roadmap is a plan, cool! You're not sticking to the plan. Is it fair to say you're not sticking to the plan?

To clarify. You guys added that statement pre V5 as far as I remember because we had the exact same discussion after slicer clipper was postponed for the second time (as of then).
Most of the people clearly perceive the roadmap differently than you guys do. And IMHO they are right.

A map by definition is a medium by which you can tell a road from A to B. You by definition make assumptions based on that.
If you're in point A in your business and you want to get to point B and you treat the engines roadmap as a map (or a road, for that particular example does not matter) that lets you guess that you will be able to reach point B in a certain amount of time. People make decisions that this road is the right one. Or search for alternatives. That often implies decisions like costly hardware upgrades (you can clearly go CPU way now, or GPU way).

If you change the map midway you let people to a dead end. That was our case with slicer/clipper that first appeared on the roadmap before V3 as far as I remember, was postponed two times, and hasn't been developed till today.
If you treat the roadmap the way you do, just name it as a "big bag of loose ideas that we might or might not develop as we see fit" and people will stop taking it serious.

But this on the other hand looks like there is no long term development strategy people can count on. If there is none and you decide from version to version - OK. But make it clear and obvious it is that way.

Same thing was discussed recently on Fstorm group. People wanted to know what will be developed next and they got no information. Just make it clear.

You're absolutely right in updating the roadmap as things progress. Im sure most people here completely understand that things change and you have to stay agile and adaptive because otherwise you just waste your own time.

I think the main cause of upset is coming from the fact that the roadmap always changes to remove features that the user base blatantly think should be a priority, but it never seems to go the other way.

I might be wrong, but i dont think ive seen it change to prioritise the things that users want the most, over what the devs think we should have (Yes there are alot of Corona users not using these forums) But then whats the need in having the poll if your most vocal and active users arent having any real input especially when user requests have been largely the same since v2.

Theres a reason people use corona over other engines and so cherry picking features and techniques from other engines instead of picking features users are telling you they want or need, seems a little senseless. Yes, the features listed under v6 should make corona faster, but they don't necessarily make the overall workflow easier or more interoperable with other software (for example realtime engines and other PBR-centered tools) and increasingly, the render isnt the end of the pipeline.

Ill still look forward to V6 as always and will actively use the RC's to help you guys get it to release though because even if the features arent exactly what the user base wants, at least they can be bug free!

Yep, I was a coder in the past :)

Nope, borrowing features doesn't mean they will become the same, because not ALL features are borrowed. So, they will always be distinct differences. Not only that, how something is implemented may be different too, because with Corona we believe in ease of use, and V-Ray believes in maximum flexibility, so there's a philosophy behind each engine that remains distinct (and always will remain distinct).

And on the plan, it's not that we aren't sticking to it, it's that plans change, and we like to keep you informed as soon as we can on what we are planning, and as soon as we can on when plans change. It's a damned-if-you-do-damned-if-you-don't of course, because if we tell people and plans change they get upset, and the other option is not to tell people, in which case they get upset. Or the third option, stick to the plan just because we said it, which would hamstring development agility.

Curious to know how is that a waste of time. This is a manner of holding to your word or not. Hackathon or not the things that emerged just recently could as well get implemented later on.
Current approach means we do not get the features majority of people voted for for about a year. 6-7mo - V6 development, as life shows 3mo code cleanup V7, 1-2mo before V8 dailies start showing up.
Fair ? Personally dont think so.

Well say for instance you put something on the roadmap and then discover that vray devs researched it and it cant be done the way you initially though it could. Of perhaps autodesk makes a change in a max update that means a feature is no longer needed or has to be implemented differently. Im not disagreeing with you that user features dont usually get prioritised. Like i said in my post above...

But the roadmap is not "our word" - it's made quite clear it is our current plans, and subject to change at any time, and it does not in any way represent a promise or commitment - just that we are trying to keep you informed of what is coming and when, to the best of our knowledge and decisions at any particular time.

Nobody has said any of this is "no biggie". We take all feature requests seriously, and we take updating the roadmap seriously. Nothing here is dismissive of any of that. It's just the truth about what the roadmap is, why it changes, and why feature lists change - that's been discussed before, as to the epic number of different factors that developers have to take into account when deciding what is going to go into one version and what will have to wait for later, so I won't cover the same ground again. I will just say that ALL decisions are always taken very seriously, and none of it is ever "no biggie" (so, please, don't put words into my mouth :) ).

Well. I do not consider myself a fanboy, not in any manner. Just weighting pros and cons.
Not being a fanboy, and just a paying consumer in "fair SAAS" model I do feel that by paying the fee that amongst current active licence and other things covers further development of the engine I have the right to know what I'm paying for. Also development-vise.

Considering the above I do believe that roadmap should be a roadmap, not a bag of ideas subject to change at any time because then how am I to predict the development direction of the engine and whether or not I still want to partly-fund the development of something that does not potentially allign with my vision of the software I need?
Taking the above into account is frequently changing "the plans" fair ? Dont think so.

Plans/loose ideas should be what they are called and you have a column for those on Trello. Core features of upcoming version should be decided before it goes into development and should be not moveable. Core features should be those that the user base votes for.
Otherwise from my POV there is no dialogue between the userbase and the development team. And it used to be the opposite which saddens me.

Corona team: as someone who works more on your side of things (making products) than the user's side, I completely understand the complexities and compromises behind decisions like this.

But I've also learned a lot about communication with customers, so I hope this helps you.

If people think the roadmap means as a promise, the uncomfortable truth is that is what it means. It doesn't really matter what was your original intention, it doesn't matter if that makes sense or not from a development standpoint (I know I would seldomly make promises, as the development process is messy by nature) ANY miscommunication is your fault, or rather, your responsibility to fix. It serves no purpose to say "well, that is not what the roadmap is for" People's interpretation of your actions become reality, regardless of how close or far they are from the truth.

You may say internally BUT WE EXPLICITLY SAY THIS MIGHT CHANGE! It doesn't matter. If people understand something else, you need to do something different. The customer is always right in the very real sense that what the customer believes becomes their reality, so you need to accept that.

I won't even question your intentions, I know decisions are a delicate balance of thousands of factors and I know you are trying your best. I trust capitalism and I know in the long term the best for your company will closely align with what customers want. I also know you have orders of magnitude more information than us. Market trends, future developments, Long term strategy, Usage statistics etc.  People in the forum represent only a small portion of the data, a very important portion, but not absolute.

So, even though my most wanted features are not part of V6 (PBR and tone mapping) I trust the vision of the product, that vision has consistently yielded good results over the years.

My advice to you is to make an even bigger effort in communicating that vision, and how your decisions work towards the vision,  It might seem redundant as most of that is obvious to you, day to day stuff, but user don't have access to that information.

Another advice (and this might be difficult because of corporate strategy, but think it's worth it) is to make development and experimentation exciting to users. I think Fstorm does an AMAZING job at this. That engine is not production-ready, it lacks essential features, but the developer is good at making people feel excited about what is to come. You can see how most of the "most wanted features" are borrowed from Fstorm. He makes people excited through good communication. 

Example: You say you developed a  new sky system that works amazingly well. We've seen 0 evidence of that. No one is excited about that. You can make us excited with a couple of posts showing how that produces better images.

I hope this helps :)

We do share the results and the differences they make, as time allows (and once development has progressed far enough) - see the thread about the new adaptive solver for environments for example, which has examples from us, and from users as they test it in the daily build.

As for the roadmap, well, the discussion has come up before, and it's really either have one, or not have one. We think it is better to have one, despite people misinterpreting what it means or getting disappointed if it changes - otherwise, we'll just have to stay silent until a feature is done, complete, and definitely out, which we don't want to do. Any other route, no matter how well you try to explain it or say what it is, always has some element of disappointment or misunderstanding, and we can live with that, as we prefer to keep those informed who do understand what it all means :)

Guys, let's not forget that there was a tragedy in between.
On top of the low morale at certain point, it's a small team too.
Changing the roadmap is totally understandable under those circumstances.

And so the advocating began.
Did someone from the team mentioned the tragedy ? I heard only about hackaton and the subject being more complex than initially it looked to be.
You also missed the chronology a bit.
The unfortunate passing of Yaroslaw (may He rest in peace!) occured somewhere around the beginning of December. I posted about PBR being in the works around 19th of December in the daily builds thread (and I check trello rather frequently) so it appeared on Trello around that date I believe.
It would be understandable that in the above circumstances the development period for V6 would have been prolonged securing enough time to deliver the features.
Anyway the discussion has aparently no point as we seem to have a new definition of a roadmap and long awaited features can be postponed at any given time :)
Guess you can either stay and live with that or leave looking for alternatives :)

" a new definition of a roadmap and long awaited features can be postponed at any given time :)

Not a new definition at all, the roadmap has always been like that, and features are never promised for that very reason - that they can change at any time. We only promise something once we are absolutely sure it can be done, with all the factors that go into such a decision - but we'll keep you informed before things reach that concrete stage (with the understanding that everyone realizes these are not promises, and it's better to know what our current plans are even if those might change, than be totally in the dark :) )

Well Tom, seems like you didn't understand my message, will try to be more concise.

There are 2 possible attitudes:

1. We tell you the roadmap is not a promise. if you don't understand it its YOUR FAULT.
2. If most people understand something different from what we intended, we need to do something different (stop calling it a roadmap, explain the changes before editing the roadmap, etc)

Seems like you are choosing number 1. I'm telling you number 2 is always the right option, hope this helps
Title: Re: The most wanted feature?
Post by: TomG on 2020-03-02, 22:42:51
There's the thing, I don't think "most people" don't understand what our roadmap is and represents, I think most of them do. Still, if we come up with a new name that might clarify it better for more people, then sure we can call it something else.

BTW, I don't know if anyone has followed a "roadmap" for a significant journey in real life and not ended up a) stopping at unforeseen times for a rest stop b) being detoured due to construction, accidents, and other unforeseen things c) taking a wrong turn d) changing chosen route for various other reasons, such as deciding that since you are close by it would be a great time to visit that place you have always wanted to go to. So I am not sure the general meaning of a "roadmap" is something that is absolutely fixed and will not change, even change significantly... always welcome to suggest a better name though :)
Title: Re: The most wanted feature?
Post by: lolec on 2020-03-02, 22:54:30
You might be right and most people get it (you can see in my original message that I understand it 100%, since as you said, anyone who has worked with roadmaps knows what's the deal) But in my experience, most consumers are not used to working with roadmaps, so the concept is a little more foreign to them.

Based on the replies to this thread, it seems like a lot of people don't share our understanding of roadmap, hence my suggestion.
Title: Re: The most wanted feature?
Post by: TomG on 2020-03-02, 23:02:46
I'll definitely give it some thought to see if there is a short yet meaningful title that might be clearer to more folks (assuming, that is, that trello will let that be changed without breaking links etc.). Or there might be some way to embed the "caveats" on the trello page someplace. Making things clearer is never a bad thing if we can find a way!
Title: Re: The most wanted feature?
Post by: lolec on 2020-03-02, 23:04:28
Another idea.

Create a buffer list in Trello between BIG POOL and VERSION 6.  This might be called something like (Feature being researched)

This would be the features that you are CONSIDERING adding to the next version, but still have low confidence.

You would add features to the "VERSION 6" list once they clear a certain threshold, maybe when you are confident enough they will be in it, that you can almost call it a promise.

Another benefit is that you can add a reason why it moves forward or back: "Moved back to big pool because it will take more time than expected". "moved to Version 6 because the code is almost done and it's awesome"

it really doesn't matter how people relate to the roadmap. The important thing is whether they get the features they ask for, and if so, how soon?

Just to be clear here, im not demanding they go and work on the user features by any means. They are a company and we are all making a free decision to use their software. Im just curious if theres some sort of overarching strategic reason.

Post by: JViz on 2020-03-03, 15:18:35
look tough guy, a major feature got shot down, we want an explanation or we are storming area bs bs something. seriously though, it's a big feature what did you expect? and nothing out of the ordinary was said above.
two options:
a technical difficulty
OR
a business decision

very reasonable actually. don't blow things out of proportions. just don't be the censorship, it's vastly unpopular these days.

This.
Each time people start asking questions there ALWAYS comes someone who's not even part of the Corona team and advocates on their behalf like he knew exactly what and when the team was doing and reasoning behind teams decisions. Or suggests that you are being disgracefull to the team because you dare to ask questions about the product you pay for.

Questions asked to Corona team should be answered by Corona team members. Unfortunately many topics in feature request section (not only here) are left with no answer at all IMHO because it works like this:
A: "hey team, what about feature X, that would work like this and that"
B (user, not Corona member): "why dou you need this, I think that it is not necessery and you can always workaround this"
...
Same goes to even slightest critique of the development subjects.

I still remember the days when Ondra himself talked to people on the forums about new features and introduced them overnight.
I also understand that things are now way more complex and this is not doable anymore.
However recently in daily build section there was a discussion when dedicated people posted examples concerning some hints about research being done elswhere on the PBR shader, diffuse model, some papers on the subject etc. only to be removed by moderators as pointless discussion. Rly ? When people try and be helpfull in any way ?

And the initial roadmap is not being followed once again and top three features from the poll are not being developed.
What is the reason behind this topic then ? This supposed to be a major version with new features and yup, there are many. Just not those that majority of the people want aparently.
Development of V6 will take over 6 months, then standard period of 3mo code cleanup version and there you have it. 9/10mo development cycle that introduces none of the most wanted (according to the poll) features ? Quite possible.

Was really hoping for that new shader with lambertian controlls, sheen etc. as well as tone mapping rework. So disappointed again.

are you for real?! I was the one who asked the question in the first place. romullus intervened in defence of the corona team, I got banned because apparently I was entitled for asking why the PBR feature was cancelled and asking for my money's worth. you got it the other way around bro, read from here to get the true picture of what happened

the new shader just got cancelled. V-ray light cache is introduced. merging the two renderers is inevitable it seems.

Removed the previous tempban on jviz because some people pointed different interpretations of his post, so it is possible I misunderstood it as attack on romullus.

So nobody is tempbanned as of now, but please be nice to each other.

Hey Ondra. did you just censor me? wow! what entitlement are you talking about! a fanboy of whom? entitled to what? corona users asking for features is not being entitled! it's asking for 1. our money's worth, 2. transparency, 3. no abuse of power, one snipe at business and you freak out and BAN me. real nice.

and again to reiterate, what i said above is very reasonable.
Technical
OR
business

you say it's technical reasons, that's check next to transparency. nobody is freaking out Ondra, you did. thanks for the ban.

"""

But I was talking exactly about the stance that Romullus here presented. You misunderstood me. I perceive it much like you do.

And aside from the whole discussion I think you should take a deep breath. There seems to be too much anger.

Noone forces any of us into using this engine. We are all free to walk away. If the trend continues that none of the most requested features (none of the topmost three voted, not even one c'mon) get implemented in a years time development cycle then I think more and more people will start to evaluate their options.

cool. anger though? I'm not angry at all. many of what I said was sarcasm that flew right above many people's heads. I don't care that much to feel anger really, all the features that corona team and vray team are struggling to understand the theory behind and code into their engines, I have access to all of those in Fstorm. it MUST be the way I WRITE that makes it LOOK like I'm ANGRY but I'm NOT. see what what I did there ;)

on a serious note, yes I thought you meant romulus but had to make sure ;)... sure we are free to walk away, I've always used more than one engine anyway, I'm just finding myself using corona less and less. it's a good engine despite its many shortcomings.

In my opinion, what would be nice on behalf of the Corona team, is to update the list/poll of most wanted features, with the option for the users to add a feature if needed.
Why? Bc it would be silly to make a decision of what users want based on the existing one because the team may be surprised by some not-so-hard-to-implement requests.

Hello there! I will be short. I think Corona highlight compression (and Filmic highlight compression) is working not very well. Look at the Camera RAW in Photoshop or in Lightroom. It works in different way and do not make bright areas so flat. As Fstorm highlight compression too works fine in this case.

Adobe ACR (same in PS & Lightroom) HC is indeed very high quality. Very smooth transition, but only at very top, doesn't affect midtones at all. I am not sure if their algorithm can be applied to linear files correctly though, it wasn't designed as tonemapping tool.
This would be worth some research into!

What Corona uses is Reinhard, and it is very bad. The filmic is somehow wrongly implemented, that's not how it should work.

oh, tired of reading, it was very hot, hot discussions are a lot of fun)
I have only one question, which I consider extremely critical - when will we have a new, good tone mapping?
Can anyone tell me the date it will be implemented or in which version of Corona it will appear?
We have everything to make a beautiful picture, good shaders, good light, but we have a terrible tone mapping that spoils all this, the picture has no depth, I'm tired of this, it is a constant struggle with burning out and a flat picture. Good shader + good light - does not work if we have a bad tone mapping. We have a great example of tone mapping in FStorm, where probably even a monkey can set up a beautiful picture. I don’t know FStorm, I don’t work in it, but I open it, set up the lights a bit and the shaders, I go to the settings for tone mapping and after a couple of minutes I have a beautiful, lively picture and it's great!
I’ve been using Corona for 7 years, I have a lot of experience, but now I can’t configure tone mapping in Corona so that I like the picture in Corona VFB, I have to save the raw version without tone mapping and then process it in another VFB + plugin or a compos program - Nuke / Fusion, so that I can correctly control highlight compress and other tone mapping settings.
If the tone mapping in Corona VFB does not work correctly, it produces a poor gray, flat result in working with bright areas / light - this means that I can not more accurately / beautifully adjust the light in the scene, because I see that the result in Corona VFB shows me bad picture, bad work with highlights and I don’t understand how it will look in Nuke / Fusion where I can more correctly adjust the highlights. If you make a new, good tone mapping and its result is as good for Nuke / Fusion, then we will no longer need Nuke / Fusion as well as FStorm. I think this is obvious and if not all, then many users will thank you very much! Because they will get a more lively, realistic picture, and this is the main thing for the render engine - this is what we all expect from you, from professionals to beginners.
A beautiful picture is exactly what helps to sell the render engine, it’s your advertisement, your money.
But instead, you want to give us a new moth of Sky, Adaptive environment light sampling and Light Cache from Vray - why?
Why are you wasting time developing a new sky model? who uses corona sky today? Everyone has been using HDRI for a long time - It gives more realism to light, atmosphere and reflections. For 7 years I have never used Corona sky and I think that almost everyone does the same, or come to this a little later with an increase in skills.
Adaptive environment light sampling - if it makes the light in the scene more realistic and works faster, then this is very good, SUPER! but if it does not change anything in the quality and speed of light, but only allows you to not use more portals - then why is this needed? It doesn’t take much time to install portals, it’s not difficult, you spent a lot of time on it, and the result will not justify the quality in the picture, if all this is to not use the portals in the windows
Light Cache - how much animation is done in Corona? basically, these are static pictures, so I don’t understand why we need it now, when we have more important things.
I don’t understand why you are doing things that don’t ask you, and ignoring what we have been waiting for from you for so long?
You have a large user base, Corona render is an excellent engine, many people came to it because it is great, but now there is a strong competitor FStorm, it has very high speed and a very good picture. Corona cannot compete with FStorm in speed because the GPU has much more speed than the CPU, but the GPU has little memory, which is an advantage for Corona, even if it is slower, but it can do my job, and FStorm just closes with an error. because he doesn’t have enough video memory, I don’t need his speed if he cannot finish the project.
You must compete as a picture - this is what your users who buy your product expect from you, wait a very long time and patiently. They write that they are interested, what they want, for which they are ready to pay money, but unfortunately you are not doing it and it is very frustrating.
If your development and user wishes do not match, then who will buy Corona?
I apologize if I wrote a lot and emotionally, I don’t want aggression, I'm just sad. You must understand - that we all expected other developments from you, not what you will give us now, after a long wait time between v5 and v6.
Probably in v7 there will be what we ask, which is very important for us, and maybe you will again do not what we ask you, but do something else.
In any case, we will not get it in v6 - this means that half a year of expectations did not materialize, now we have to wait another half year again and hope that they will fix it, they will do it in v7
We want to understand how long we have to wait.
Maybe we never get them, or maybe we get them too late.
There are things that are very important here and now, tomorrow these things can be useless, because we already found a solution from competitors, because we had no choice, because we really needed them yesterday.

You created a vote for new features among Corona users, and I think it’s fair if you indicate the time when we can get them, it will be useful for everyone, we will know when we get it and we won’t be upset that the new version of Corona they are not there, we will know how much time we will expect this and probably will take serious decisions for us - wait for us for so long or seek solutions from competitors
Good luck Corona team, I hope you understand what you are doing and that you have chosen a truly right direction of development.

Funny, at the moment I also more and more put an eye on realistic tone mapping color grading, dynamics, etc... and I see that many of you guys out here ask for a good solution regarding those things that actually differ a render that's okay from a render that looks real.

In the last days I often thought that it would be cool to have an "intelligent engine" within Corona, that permanently corrects users´ light tweaking, so it always looks realistic.
Highlights, contrasts, mid tones, saturation, etc. Like an AI-engine that works in the background.
Title: Re: The most wanted feature?
Post by: agentdark45 on 2020-04-20, 03:20:44
Basically, if Corona copied FStorm's tonemapping 1:1 I would most likely never touch FStorm again (apart from simple animations with DOF as it resolves DOF noise so damn quickly).

The user request vote has had reworked tonmapping in top spot for months (years?) - please devs can we put focus into this over items that users have not asked for. We can live with any current quirks of Corona (Reflection environment overrides not working, microbumps being resolution dependant e.t.c)...but FStorm quality tonemapping would be a fundamental difference to the engine.

I spend at least half a day per project fighting with highlight compression, curves, various LUTS, post pro trying to get a decent image without murky greys/crushed blacks/over burnt highlights/washed out or super saturated colours in Corona, whereas as Yuriy mentioned - it is literally minutes of setup to achieve a bang on DSLR like result in FStorm.

Cliff notes:

- 10-15% future speed up, consuming months of dev research and testing...meh.
- ACES/FStorm like tonemapping: inject it straight into my veins.

In VRAY it is possible to zoom in a certain area where you expect errors , correct the error and see the change on the fly!!

the latest features in corona are a dead cat bounce. the new Vray Beta has many features already in corona AND adds new ones like sheen and clear coat. Vray is ahead of corona right now, very soon there won't be any reason to use corona over vray. I would ignore both renderers and use something entirely different, many options out there and way better.

There will be improved post-processing/tone mapping in Corona. You will be surprised.

Other than that, check out the roadmap for V6:
- Render elements in reflections/refractions - big thing
- Adaptive enviro sampler - faster rendering
- Phoenix foam support - big thing, requested by many users
- New sky model - not a breakthrough, but warmly recepted
- coming up: new bloom and glare - helps make things more realistic
- coming up: new secondary light solver - faster rendering, no flickering
- coming up: blue noise dithering - faster rendering
- and more

The devs are working hard, and we do listen to the community. You can't call it "dead cat bounce", just because one aspect of Corona rendering is different than that of another renderer (and still by no means bad!).

No-one has said how long the wait will be at the moment - for one thing, historically Corona has 2 versions a year, not one, so waiting a year is not something you can assume :) Of course, it's not been planned whether it is in Corona 7 or not yet, as we are working on finishing Corona 6 before we set to work on hammering out which features will be in 7, and when the expected release for that might be.

I already wrote about this earlier
more correct work with highlights
Shadow correction in Input Lut Log mode
support OCIO / ACES / ICC
You can also see tonpaming in Fstorm. what functions does it have and what excellent result does it create
I think we have a large selection of development that will benefit everyone.
Maybe I'm wrong, I need to check, but Corona creates a Vignette as an effect in Photoshop, not considering which lens is installed in the camera, in the old MentalRay Vignette worked with the lens installed, the Vignette changed the same way the lens shape changed - this made the Vignette effect very lively and natural
Title: Re: The most wanted feature?
Post by: Yuriy Bochkaryov on 2020-05-14, 15:30:11
see how Vignette works in MentalRay and in Corona
the picture shows how Vignette in MentalRay changes automatically from changing the lens in the camera, which makes the picture more interesting
at Corona Vignette works like an effect in Photoshop, it ignores the lens settings
Why don't we do this in our Corona?

I don’t have the opportunity to check the physical correctness of this, but theoretically Vignette should also change depending on the size of the lens, it seems to me that in MentalRay it works more correctly, although this is not a super important thing, but if it is not difficult, then it can be done in the new version

AFAIK vignetting mostly depends on specific lens construction. There's no specific amount of vignetting tied to certain focal length, so it's not clear how this should be implemented. I think it's better to leave it on user's decision, as any in-built implementation would be arbitrary anyway.

If it supports ACES and you can save the image as DNG like a camera (like what Juraj said), I'd be happy. Then you can treat Corona as a camera and do the post production elsewhere.

- coming up: new bloom and glare - helps make things more realistic
- coming up: new secondary light solver - faster rendering, no flickering
- coming up: blue noise dithering - faster rendering
- and more

This sounds like music in my ears!

I personally do a lot of animations and "no flickering" sounds amazing always and faster rendertimes means faster rendering frames for anims.

Please Please please add back the Curvature Map plan for Corona 7 (which was taken away from the update 6 back to consideration in Trello) ....or improve Corona AO for.
It is really hard to use Corona AO in its current state for hard edges mask in maps. If you make it to strong, the AO map will make every edge have shading, so the only solution is soft edges which are difficult to control. I use this feature so much for quick materials that don't need extensive texture work.

This is my most wanted feature right now, because its something I use almost every day and it's not behaving great.

Could we have the option of adding other features to the list? I understand that some may be impossible to do for Corona, but may trigger ideas for you, and it'll give you a better idea of what exactly is it that the majority want, by not being forced to choose from a set number of features.

Best thing to do for that is to request the feature here as a comment. It's best the list remain curated for various reasons. EDIT - so if you request a feature here and say please add it to the list, we'll take that into consideration and update the list if it makes sense.

Since Corona is mainly used for interior renderings, and there are fabrics in each of them, I would like to suggest considering the introduction of a separate shader for fabrics.
I work quite closely with fabric in all its variations and came to the conclusion that corona render cannot currently provide an effective tool for rendering it realistically, and introducing sheen and velvet attributes in coronamtl will not fix the problem. Geopattern can partially solve the issue but we dont have it.

In 2017 viscorbel created a thread https://forum.corona-renderer.com/index.php?topic=16327.msg102846#msg102846 (https://forum.corona-renderer.com/index.php?topic=16327.msg102846#msg102846) but did not receive any comments from the development team.
There he mentioned the ThunderLoom plugin that uses the Irawan shading model (introduced in 2012) with pattern determination with WIF files to correctly recreate the reflectivity of individual fabric strands, with the correct anisotropy without using falloff fake approach.
Now i can create any texture in substance designer but cannot use it properly to explain my render engine what i want from him))
Basically, we need something like CoronaHairMtl but with the ability to apply it to regular surfaces, imitating the thread pattern by using texture maps or wif files (moreover, the basic set of patterns can be included in the Corona material library), with separate fuzzines setting, ability to use bump and normal maps for initial mesh, not for individual hair strand only, both for adding wrinkles and for imitating thread volume.

Since I have tried a huge variety of approaches to creating fabric, I have a large pool of ideas, especially concerning UI of this feature. I hope the developers will pay attention to this issue and in the future when someone sees a beautiful fabric on the renders he will say "oh, probably it was rendered with Corona"

ACES / OCIO / ICC support in new framebuffer with new tonemapping

It is also very important to be able to turn on caustics on only one object, now caustics are calculated automatically for the entire scene, from everything that has a reflection, and there are reflections even on leaves and grass - why waste resources on this?
there should be two modes for calculating caustics:
1) enable globally - when caustics will be counted at once on the entire scene from all objects
2) switching on individually - this will work only on those objects that I have marked, I do not need caustic from all objects in the scene, I want caustic only from the stele in my exterior, if caustic will be counted only from one or several objects I have selected, this is will greatly speed up its work and improve the result
we also have the ability to exclude / include objects for rendering caustics in Corona Light, but I work in exteriors and always illuminate with HDRI and then I cannot include / exclude some objects, I just don’t have that possible - there is no function to include / exclude and therefore, if I want caustic from glass or water or metal, then I have to count it on the whole stage, on everything that has a reflection, it turns out that caustic begins to be counted on both grass and fox trees and where I don't need it, but I wasting my time

I also want to be able to add texture in glare / bloom to get interesting beautiful effects, for example, fingerprints or dust on the lens, your new generator from Vray is good, but it has limitations, it will be much more convenient and faster if we can just load textures for the pattern as it has been for very many years in Maxwell render and MentalRay, just add a button for the texture

please add a Coating layer to the base shader - this will help you make machine paint, objects under varnish - for example, wood with a varnish layer applied on top, soap bubbles and much more
I don’t understand why this is still not there, this is a very important thing, around us there are 30% of objects that have such material in life - cars, wooden floors, wooden furniture, everything that has a transparent varnish coating
and no need to say that this can be done through the layered material that is now because this is not correct
the layer material mixes the shader, it has 100% and no more, that is, you can make 70% base material and 30% make a layer with reflections - but this is not correct, since the varnish is applied on top of the object, and not mixed, this is 100% of the material + on top of a layer of varnish, which gives reflections and has a thickness

There are a lot of ideas and I am ready to share them if you want to listen)
I would like you to add new functions faster, our life is not endless, we waited a very long time for the release of version 6, you developed much faster and listened to users better while you were free, now you are part of the chaos groups, we were promised that it would be good, additional funding and a large team will speed up and improve development, while unfortunately we see something completely different (
I hope that I will not have time to die of old age when all this will work in CoronaRender.
I still believe in you guys from the Render Legion! )

there is no way to greatly speed up the rendering by optimizing the render engine, over the years it has already been optimized almost to the maximum
render engine is a set of formulas and algorithms by which the calculation is performed on the CPU, you cannot change the formula to make it work faster, otherwise it will not be correct.
The only way to increase the speed is to buy good new CPUs, AMD now offers good solutions for its money.
To put it simply, you cannot greatly speed up rendering through programming, only by increasing the power of the CPU.
There is also an option to make a hybrid with a GPU, and it will definitely be in the future, since this solution greatly speeds up rendering and this is the future, but it is very difficult and it is a very long process
so if you want more speed here and now - buy new powerful CPUs
so it makes no sense to spend a lot of development time to get a maximum of 5-10% of the real increase in speed, it is better to do something more useful during this time - a new PBR. Parallax, new tone mapping, etc.

Exactly, the amount of time that passes between major versions of corona isnt enough for there to be much significant increase in hardware capability or code efficiency except by throwing more processor cores at it *Coughs in AMD*.

Speed improvements are great but in the long run they arent sustainable because they become counter productive to spend something like 30% of your dev time trying to gain what could be a 2% speed increase in one area of the software. It could be used to develop a new feature that makes another area of the production process easier and faster and more flexible so maybe the speed isnt as necessary. Like lightmix layers for textures and materials. A small speed increase wouldn't matter there because if you only have to render once to be able to get multiple versions of a render, you're saving time by not having to render over and over again. Theres your speed increase.

We should stop focussing on the speed of a single render and start looking at the bigger picture of the volume and flexibility of work we can produce with one click of the render button.

In theory that sounds ok, but maybe the devs know something we don't know, maybe they can indeed optimize and get more speed still from their code. The "speed improvements" was put on the poll by the devs right ?

And maybe the speed improvements can be not some simple brute numbers or percentage increase by doing some super magic tricks and just increasing all renders by 30% . That doesn't sound plausible indeed.

But instead they can increase the speed by making the render engine even more "smart" . For example the engine should somehow know if most of the image is just blank, or a white wall without much happening in terms of shading, details or reflection and that part should render super fast. Other render engines seem to have an edge in this regard and render much faster if not much is happening on the screen, like maybe for compositing reasons most of the screen is empty.
 Or maybe you do have a minimalist scene with lots of huge walls without details. Corona seems to render these pretty slow.

I think more and more people want to use Corona for animation too, not just for stills. And I think this would help that.

(and I voted for  lightmix layers for textures and materials)

Oh absolutely im not criticising the devs themselves and they obviously know their codebase more than anyone especially what needs work and they probably already know what needs optimising. But im just guessing that a specific speed improvement wouldnt even touch the speed gains you'd get from not having to render multiple times. Its the same for GPU rendering and things like geopattern which would give a speed increase in scene modelling and prep time rather than render time. The speed gains youd get from being able to scale your render speed simply by adding another GPU would probably be vastly more than what you could do with software alone. I just think alot of users get stuck on the speed that they can render one image locally, which in a well made scene is already just as fast as any other CPU renderer if not faster and alot simpler. Voting "speed increase" to me is too vague and pretty much all of the features listed would give some form of speed increase in the pipeline directly or indirectly.

P.S. What youre talking about there is the adaptive engine and corona indeed already has that and will focus less samples on areas such as big blank walls. This is why skies will render clean very very quickly.
Title: Re: The most wanted feature?

About a year ago I did an animation test with Corona. Not sure what version it was but probably already had the adaptive engine.

It had a very pleasant... I don't know what, lighting ? colors ? It was pleasant everything. Even though it was a simple plane, a little bit of corona sky behind and a small animated object. Fixed camera. And I was a little troubled to see that the speed of rendering of just the empty plane ground and the sky was not much different if I added the object in or not. I felt like the speed of the empty scene should have been much much faster.
  It felt stupid for me to wait for the renderer to render 1000 frames which were all identical between them save for the little bit of moving render noise or grain and 25% of the image occupied by the animated object.
  So I managed to animate a small render region just for the animated object and of course that went way faster.

Then I saw here on forum other people with the same problem, I even tried replying that they can also use this method - animating a small render region to follow the moving object, but they were not interested, they were just upset that Corona takes that much time to render a static simple scene or a large plane.

I also tested a few other renderers, I don't remember which ones, maybe even IRay ? Not sure, but some renderers, like one would expect, had a much greater speed increase if you had the animated object in the scene, or not. Also a great speed increase for the portions of the scene without details, if it used bucket rendering you could see the increase in speed.

Concerning tone mapping that is to be overhauled.

Not sure if you guys came across Raya for Photoshop that works on "luminosity masks" -

I'm not a coder, also don't even try to grasp the science behind tonemappers etc. but maybe this could be implemented internally in some way as the results the guy achieves using this are quite nice and the better the more different exposures of the picture he is able to use.

In Corona VFB we can get unlimited number of exposures. Mixing them in a smart way could help bring back all the detail in the shadows area and also exposed areas of the image without flattening it with Reinhard etc.

@Maru - have you guys thought about this kind of approach ?

I had to check but thankfully it looks like you can, at least 90perc. of them :- ). Looks to be mainly the popular big-hitters, like Ryzen 5900X or Threadripper 3990X which are hard to source (but plenty of 3995WX for 5.5K Euro..uff).

Ever since the WX series arrived I've noticed extra stock for those yeah. Last month or so I was scouring the shops for anything TR like and nobody had anything except a couple of shipments here and there. But most hadn't and the ones I asked didn't know when the next batch was coming in. Looking at some of the more popular retailers, looks like there is more stock in there now too - at some extra prices :) Non TR stuff is luckily more accessible though.

Crazy times! I wouldn't be surprised you'd get PMed, even a 1080ti is worth A LOT these days lol. Talk about holding value over the years...

Lightmix needs to be like it was in corona 4.0 and below versions. Its was really good before where we don't have to save lightmix as a preset. For latest versions, Even saving the preset It can not remember the values/properties for the lights based on the names.

please find attached screenshots for your reference.
For the 2nd render, I have added extra lights after saving the preset, but you can see even after loading the saved lightmix preset, It cannot remember the name and properties of existing lights.
In the screenshots you can clearly see the values of light 001, 002 and 003 is swapped to box light, box light001 and box light 002 respectively. so basically it just works based on the order of the lights. It would be better if it can remember the names of the existing lights.

I Hope there will be a fix for this issue for the upcoming corona version.

highly recommend for a huge render time saving add to Corona Camera-- parameter of denoising amount and passes amount/ so it will be possible to adjust the render time for different cameras. since there are different positions where half of the image is empty. for example for aerial views where a large number of unnecessary passes are rendered after reaching the required number of amount noise and quality.it will also be possible to reduce render times for views where the visible quality is sufficient with fewer passes, or more noise amount/

Nope, this has never worked. The camera has always had to be outside the volume. There are examples of things like cloud fly-throughs, which can be done by using render time booleans (make a sphere around the camera that follows the camera, make the sphere a render time boolean that cuts out that shape from the volume object, now the camera is always outside the volume object :) ).

It's honestly the best plug-in for max and makes it a much more friendly software to use.

IMO, it sounds great but unless this feature can sort of retrofit the materials in 3Ds max with the chosen textures so the next time you render you have the textures applied and not have to do that manually, I see it as a problem in terms of workflow more than a time saver. I'd rather do this in photoshop (maybe with cryptomatte) if there was a way to use the UVs info like in Motiva Colimo.

Personally, for the 'material mix' or whatever you're calling it... I think it'd definitely be handy to edit the color/tone of the materials in the VFB, but anything beyond this seems a bit convoluted and unnecessary. There is already so many great features to quickly edit a material, or portion of a scene (selective render for example).

Additionally, I already quite often avoid using light select as the CXR file sizes very quickly inflate beyond manageable sizes and project folders become huge to store/archive. I fear this would only exasperate with 'material-mix'.

Just my two-cents :)

We've changed how we're doing the roadmap - the next version is no longer a long, comprehensive, and exhaustive list at the release of the previous version, but instead contains the things we will be working on first. Once those near completion and it is clear we will have time to do something else, we'll move another item in off the "Pool of big ideas". This is to save the frustration of listing everything we hope to include, but along the way we find out that something can't be completed in time - as happened with the Tone Mapping for 7. Even though it is made clear that the roadmap is tentative, we thought it would help manage people's expectations while still being as open and transparent as we can if we follow this new approach.

So what you see in Corona 8 is just the starting point. What else gets added as we go, once things near completion and we can safely wrap in other work from Pool of Big ideas, we will find out as we go. As it says right on the roadmap, "More to be announced later..." :)

FStorm recently introduced their "Fstorm Fur" and it works like a charm. It has simple interface of the modifier and low memory use.
Would be really useful to have that kind of feature in Corona for rugs, cloths, etc. Using default 3ds max "Hair & Fur" is real pain in the ass.. Especially problematic is that when using corona shader for hairs it can't pick up color from diffuse map.

"I'm agreeing with Loocas on this one - Corona is already fast, so I thought it would be better to add something entirely new instead of speeding it up more. But evidently people want it;)"

We are probably the only studio in the region that is developing a completely corona render / Unreal 4/5 videogame.

Here the boys and I need precisely this:
A corona / unreal transporter Plugins / tool similar to Vray's would be something that would benefit everyone. Today, many think about corona vs Unreal and I think that nobody has understood well how things are going.
It is corona render / unreal, not corona vs unreal. But I repeat, only we need something like that so that our study can advance thousands of hours of development that today we lose with Datasmith as a max / unreal tool.

If we had at least Corona render / Unreal on that list, it would be a step ahead for Ondra's team to even consider it, since it does not appear even in their official Trello.

Corona Render plugins for Unreal engine 5

Our entire library is in corona render, and we already have hundreds of assets made and many entire scenarios already configured. We have no turning back.
We are very proud to be one of the first studios to work with corona render / Unreal, whether we finally have this plugins in the future or not.

In the past we paid a developer who developed a plugin to view the corona render materials within unreal, very similar to how you see them in max. But the process was slow, and we continue to pray for a tool that cuts hours.

Sorry for my doubts, Fstorm calculating some prepass, that makes render on the latest passes more effectivity, then Corona. It is cleanup the image better, while Corona do not cleanup the images and staying on the same noise level for some areas in the internal (for example corners inside room).

Well, if you know how Corona and Fstorm works internally, then feel free to ignore my argument, because i don't have such knowledge for sure. All i know is that Corona has adaptivity since 2016.

while Corona do not cleanup the images and staying on the same noise level for some areas in the internal (for example corners inside room).

Do you have a scene where the noise stays on the same level for a long time? This sounds like a bug.

As far as I know, Corona was never able to clean the image entirely. I thought that was the main reason why denoising came to be.

Maybe what the OP is referring to is that Fstorm starts cleaning the whole image, then when certain areas reach a threshold, it continues to smaller areas where there's still noise, and so forth until it tries to resolve the last parts of noise.
In Fstorm it's easy to see because it has a render element that shows this clearly. You can actually stop to change the threshold and then continue processing the image until you're satisfied with the noise level.


Just my 2 cents.

Which is pretty much what Corona does - there's a render element for it too, the SamplingFocus, where white shows where Corona is focusing most of its processing (areas with noise) and black where it doesn't need to spend so much time calculating.

Denoising came to be simply to reduce how many passes you have to do in order to get a clean image :)

The attached is a simple scene.
It's very hard to make any sense from the SamplingFocus element.

With Fstorm (as far as I remember), in red you can see the areas that didn't reach the threshold yet, in green the areas that did, and in black the areas that have no noise (I think).

From the sampling focus element in this example, to me it's like Corona is trying to solve some random lines.

I just wanted to emphasize how crucial it is for some projects to have an easy object outlining solution.

Yes, I know about the "copy your geo and flip it" and the "just use edge texture + ao" workarounds.
They work sometimes, but there are enough situations where it doesnt or where its not feasable.
And yes, I could use a different renderer for that, but thats a hassle, because upon changing it, Corona`s settings are reset and I need to composite the two renderings in PS, too.

I tried to remedy the lack thereof through OSL, which is futile, because OSL can not get the needed rendering information in the MAX implemenation.
ShaderFX doesnt work, because Corona does not support DirectX shaders.
Another idea was to somehow maybe render the artistic viewport shading styles onto the image, but how would that work and also, they do can not be changed (Edge Width, etc.).

According to the roadmap this feature was already twice on the agenda, for versions 4 and 5, but since has been neglected.
I feel like everything else on the poll can either be done by someone who knows a bit of Python or Maxscript (adding materials to the library => just make your own library plugin, dont bother Render Legion), can be discarded (GPU/CPU hybrid rendering => come one guys, we all know thats not gonna happen and there are plausible reasons for that), can be easily be worked around (Why the need for a decal system? Just put a composite map into the diffuse, or use a mix material, then set your bitmap to not tile and to a unique UV ID. Then unwrap that with a unique UV Map modifier...) or plain ridiculous (Why even bother with in viewport rendering? I dont get how in a professional setting that would be benefitial...).

The edge map however is not so easily replaced. And it has real production value!
So, I literally beg you to please make our lives easier by adding something along thiose lines.
Object outlines, plus creases where to objects are stuck into eachother and an option on how thick those lines are in relation to the resolution.
That would be awesome to have, thank you!

I use Corona Renderer every day on 2 PCs in my office (for 4 years) with 3ds max 2018. I believe there should be support for Blender (as plugin). Also I need GPU/Hybrid support. I have two RTX 2080 cards that are not used. The GPU would come in handy when rendering small scenes. In my opinion you add small changes, but without the GPU the whole rendering is very slow (I have compared to Cycles X). Corona is the best when it comes to realism and ease of use, but without a GPU there is no future.

What should be added/improvement? :

- GPU/Hybrid rendering
- toon shader
- outline shader
- I'd like to be able to render shadow catcher as a separate pass.
- DR has a lot of limitations and bugs. Nodes cannot be reset remotely. DR additionally, they need a 3ds max installation. (btw. DR has a bug that it doesn't work properly if the one viewport window in 3ds max is maximized. In this situation, the nodes go crazy. Start rendering and end after 1 pass. Over and over again.). It is very inconvenient.
- Blender support from Corona team.
 

Btw. sorry for eng :)

I don't agree that without GPU rendering there is no future. Especially since CPU market is starting to be super sompetitive again which means better products for consumers. Intel is finally awakening with Alder Lake and AMD is showing no signs of stopping either. Also, Apple M1 is pushing both of these to get better/competitive (especially Intel).

But most importantly, as explained by Corona team, CPU is capable of producing more beautiful/realistic results than GPU at cost of speed. I choose quality over speed and in my opinion Corona render is pretty fast given the results it is producing.

As for adding support for other software, I would rather have them focus on existing two and continue rapid increase in quality of Corona Render

I don't agree with this at all, speaking as someone that's used Corona for years, and FStorm for several months (commercially). Take a quick browse on the FStorm Facebook group for an idea of render time vs quality. Unfortunately Corona isn't coming close any more.

Secondly, the cost to performance (coupled with convenience factor) is definitely skewed in GPU rendering's favour, given that we now have 24GB GPU's (roughly equivalent to 128gb-256gb of system ram imo due to how efficient ram usage is with FStorm + the option of memory compression). What's more convenient/cheap; building out multiple 3990x machines and dealing with DR annoyances vs. simple dropping in as many 3090's as you need in any machine with lots of PCIE lanes. Another negative of CPU rendering, having to build an entirely new system every time a new socket/platform gets released, or being potentially rugged in the future by workstation only platforms i.e. Threadripper pro as your only upgrade path.

I don't want to sound like an FStorm fanboy, but I'll go with whatever software gives me the most benefit. It's a shame to see the Corona devs dig their heels in on the CPU/GPU debate when there IS a clear current and future benefit to GPU/Hybrid rendering.

I agree with that quality in rendering has nothing to do with GPU vs CPU, but there are cons of GPU as well. If you look at the media library on FB for Fstorm, there aren't huge exterior scenes. Memory in GPU rendering must still be a big bottle neck.
Also video cards do have their problems too. Many times I read in the Facebook page of Fstorm someone with issues with GPU and I feel relieved that I don't have to deal with all that.

What would you classify as a huge exterior scene? The groups banner photo seems pretty sizeable: https://www.facebook.com/photo?fbid=1355093498211047&set=gm.2514144842215252

If you spend some time with FStorm you'll realise that it doesn't use GPU memory in the same way Corona uses system RAM, hence why I've likened having a 24GB 3090 to the equivalent of having 128-256GB of system ram with Corona - it is insanely memory efficient. I've made scenes using 60+ 4-16K textures, mega detailed photo-scanned assets with silly amounts of scatters and was barely over 9GB of GPU ram usage (which could get reduced to ~5GB if you enabled memory compression). I've also done ridiculous 32K renders on an old single 2080ti that were impossible to pull off with Corona.

I would agree that GPU's in general are probably more prone to failure than CPU's, but we are splitting hairs here tbh. High end PSU's and adequate cooling are needed both CPU's and GPU's. You'll find all manner of problems on this forum with people's systems (VRM issues, throttling, proper core loading e.t.c).

My current machine has a 3970x and 3x3090's all water cooled, which has given me a good opportunity to properly test both engines on real world commercial scenes. I tried hard to not gravitate away from Corona (as it was my daily rendering engine for the best part of 3 years, and the lightmix feature is absolutely fantastic), but the benefits of FStorm far outweigh the cons.

Yes, that definitely classifies as a huge exterior scene. I wonder what kind of card they used, because my impression is that you'd need a much larger investment to create  a scene like that in Fstorm than with Corona.

Other than this one image that you showed, I haven't seen anything done in Fstorm with that scale. While with Corona there's tons of examples.
If you know more examples of larger scenes, I'd be interested in seeing them.


In other words, yes, GPU rendering is great if you're willing to spend big bucks for a system.
Otherwise Corona is more wallet friendly in terms of system requirements IMO

It was rendered on a single 2080ti and only used 2.75gb of VRAM...in other words it could be rendered on a toaster: https://www.facebook.com/groups/FStormGroup/permalink/2432656570364080/

I was using a single 2080ti for quite a while which was faster in equivalent render time to my 3970x in complex interior scenes using Corona. You would need to invest a hell of a lot more than what I paid for 3x3090's to match the speed using Corona, and then have to deal with distributed rendering.

Quoting from Corona article "When it comes to light bouncing around in a 3D scene, it DOES skip all over the place – exactly what calculation is required next is not easily predictable, and it may not be the same as other calculations which need to be happening at the same time, and that is why the architecture of a CPU is much better suited to this task than a GPU."

And from Autodesk "The most notable difference between CPU and GPU rendering is that CPU rendering is more accurate, but GPU is faster"

Although I have to say FStorm seems to produce most beautiful renders among GPU render engines, very impressive but I still prefer Corona or Arnold.

This is patently false information, is this from a 4 year old article or something? Are we to believe that for some unknown reason that accurate calculations cannot be done using CUDA on GPU's...despite the scientific community using them daily for exactly this purpose?

What has been described in your quotes is purely down to the algorithms implemented on a software level (it makes no difference what the underlying hardware is in this context). If anything I've found Corona less accurate with GI calculations than FStorm due to the biased secondary UHD cache of Corona - try rendering an animation with multiple moving objects/light sources, or compositing newly rendered regions in a render in Corona; you're going to have a bad time (admittedly the devs have somewhat solved this with the 4K cache, however it's still an approximate solution). You do not have this problem in FStorm, the GI solution is tack sharp and 100% repeatable even with moving objects and light sources (not to mention no precomputation of secondary caches are needed).

It's not a joke for me. Not having Crypto Mattes is so weird. It's just another of those industry standards that the devs seem to look past. Nothing says fun render engine, like wasting time setting up mattes for a million shots.

Hello!

I specifically registered on this forum to ask for a solution to this problem. The Corona renderer has a function to save the history of renders. But it is not functional enough. Even in Vray in time immemorial, it was possible to close the stage without resetting the History. That is, after opening the scene again, it was possible to load the render and make the necessary edits to the region. It is very necessary that the History be saved after the scene is closed. Then this panel would be much more functional than it is now.

Thanks!

I've been working with Corona for like 3 years, almost with advertising projects, for 90% of the projects Corona handle all the things I need to do, but and sometimes I need to use other renders because there is some things that are lacking in Corona. SO I would suggest these features:

1 - ACES color management support: more than one time a client would ask me to bright up some area, and the color just don't work as good as ACES work, there is one time that a client wanted a bright light in a red ground that was supposed to turn orange with a stronger light, but it just clipped the reds, we ended up doing this light in PS. Vray, Redshift, Arnold and other renderers already have it, it's the new standard.

2 - Tyflow support:  I make a lot of animations using tyFlow it lately, but sometimes I need to switch to redshift or Vray to use motion blur in particles with changing geometry and other stuff that are not supported in Corona.

3 - More control over rendering volumes: Was doing some smoke and fire sims for a client and could not get great control rendering the volumes, had to use V-Ray instead that had a lot more options.

For me this is the top 3, there is other stuff that I would suggest too like cryptomatte support, dome light to have the possibility to exclude the HDR for an object, or just apply it to one object only, better OSL support......

Thank you!

Andrey Kozlov says that is working on a new type of raytracing:

Quote
Working on a new ray tracing acceleration structure. Ray tracing speedup up to 5 times on heavy geometry. Faster than Nvidia RTX. Faster geometry compilation up to 2 times.

so faster rendering paired with better tone mapping and memory-consumption improvements would be nice when possible

Since Corona is mainly used for interior renderings, and there are fabrics in each of them, I would like to suggest considering the introduction of a separate shader for fabrics.
I work quite closely with fabric in all its variations and came to the conclusion that corona render cannot currently provide an effective tool for rendering it realistically, and introducing sheen and velvet attributes in coronamtl will not fix the problem. Geopattern can partially solve the issue but we dont have it.

In 2017 viscorbel created a thread https://forum.corona-renderer.com/index.php?topic=16327.msg102846#msg102846 (https://forum.corona-renderer.com/index.php?topic=16327.msg102846#msg102846) but did not receive any comments from the development team.
There he mentioned the ThunderLoom plugin that uses the Irawan shading model (introduced in 2012) with pattern determination with WIF files to correctly recreate the reflectivity of individual fabric strands, with the correct anisotropy without using falloff fake approach.
Now i can create any texture in substance designer but cannot use it properly to explain my render engine what i want from him))
Basically, we need something like CoronaHairMtl but with the ability to apply it to regular surfaces, imitating the thread pattern by using texture maps or wif files (moreover, the basic set of patterns can be included in the Corona material library), with separate fuzzines setting, ability to use bump and normal maps for initial mesh, not for individual hair strand only, both for adding wrinkles and for imitating thread volume.

Since I have tried a huge variety of approaches to creating fabric, I have a large pool of ideas, especially concerning UI of this feature. I hope the developers will pay attention to this issue and in the future when someone sees a beautiful fabric on the renders he will say "oh, probably it was rendered with Corona"

I hope they have plans to add an ANIMATED feature for Vegetation, Humans and Cars.
I hope they throw in some time lapse HDRI s too
...and I'm personally requesting for more colored human posed models in your collection, in both formal and traditional attires. you would be surprise how many African nations are into corona. ;)

I get the reasoning behind why it's tricky for the developers but hear me out: CPU's are a dead end for render engines unless you have unlimited resources.

Lets look at recent shifts in the hardware space objectively. Lets take the Threadripper platform, the 3970x & 3990x are dead ends - single sockets that only lasted a generation and are now not even being made by AMD. AMD then decided to shaft everyone with "Threadripper Pro", costing 2x as much for just the CPU, then locked it down further forcing consumers to buy a full system from Lenovo. It's questionable whether AMD will ever make a non-pro "affordable" Threadripper again.

Current reports are intel are still scrambling around to get anything close to a 3990x.

Now lets look at Nvidia: you can get a 3090 for £1400 retail. You can stick as many of them as you want in any high PCIE lane motherboard going back generations, DDR RAM version agnostic. Reports are the 4090 is set to double the 3090 in performance.

With the above in mind, tell me objectively which method of rendering offers consumers/businesses the best generational leaps in performance, flexibility, upgradeability and cost?

Hum well, ok, but things have changed quite a bit I'd say. When you see that things like for example "In Vaulted Halls Entombed", one the last Love Death & Robots episodes, has been rendered with Unreal AFAIK ... let's talk about it in 10 years ;)
Any trolling or so apart, I think there will still be room for both kinds of renderers for some time. That doesn't mean neither one can still ignore the possibilities of real time engines .

The reason this is included is that we want to see how many people want this. This poll is not a binding contract that we need to blindly obey, even if it would mean stopping regular updates for 3 years. It is just a way to scout the market.

NicolasC: you are mixing "GPU rendering" and "real time rendering". "GPU Corona" would not be 60 FPS game engine. It would be an offline ray tracer ported to GPU, with some features missing, but able to scale with multiple GPUs in a single machine.

Oh, the layered shading system with the ability to add several layers of clearcoat and thinfilm with the correct interaction can be sooo useful, because when creating any material that goes beyond the standard framework even a little, the basic physical material is inferior even to legacy and you have to come up with very tricky ways every time and about the fabrics I'm not even talking)  It's a pity that this item is not upvoted as well as for a separate fabric shader

It's pretty much never safe to switch if there is even the smidgeon of a possibility you will at any point want to go back to an older version of Corona. Of course you can install and run old and new versions alongside each other, so new projects can be in new Corona, and ongoing projects can remain in previous version Corona. This means one long ongoing project doesn't have to stop you taking advantage of new Corona coolness in your other projects :)

I havent had any issues yet but i dont use LUTs in the frame buffer often. I just have a big use case for decals where i was having to make alot of composite materials and layered materials to apply texture elements very frequently and the curvature map for applying wear/dirt.

In my opinion these are patches which could have been added as 7.1. Sorry but these are not changes to be called a new version with double price. I'm more interested in having more GPU based speedups and a full-fledged Corona add-on for Blender (not an exporter) than access to Cosmos that is just a Chaos service and Scatter that is just another way that I can obtain with already buyed ForestPack.

I would stay with lower priced Corona without Cosmos and Scatter. These features are just excuse.

I see the poll has been reset. Could we get a post That explains some of these? I don't have a clue what the Tiles Map is supposed to do. What would be the improvements to the CIE, would that not also mean that we improve the frame buffer. And what is meant whit new and better frame buffer (docked and floating)??¿

And I have a small request regarding the frame buffer. This is something that has been bothering me for some years now. Why can't we compare two different images that have a different size. This is most annoying when you do an IR and than you restart the IR and it has a different resolution. Now you can't compare them. This has been a feature in Vray for years. It's not a deal breaker, just a bit annoying at times.

Procedural clouds would be great addition for me, even if not very physically accurate or photo realistic.

I'm pretty sure Vray implementation was done in the way clouds affects the lighting. That's what I was actually the most amazed by and I really look forward to seeing it in Corona.

I'm sure the quality will be upgraded with time (as was the case with CSky models), but if it's like what's available in VRay, it'll will be yet another great tool to control the lighting and general mood. At least!

They do affect the lighting (basing this on the V-Ray ones which I played with quite a lot), so you can have them cast shadows on the ground for instance, and as the clouds animate and move, so the lighting changes and an area can move from being in shadow to being illuminated. It's rather cool. Of course the clouds are rarely the "point" of an image and not meant to be what people are looking at, just to fill in the background, and they work great for that (without the render time hit that comes from a full volumetric solution).

Even when they're not realistic enough for direct visibility, they may be invaluable tool for modulating the light quality (both inside and outside).

I didn't think of this. Good point.

Woah :o

If you don't mind I'd like to ask an under-the-hood question...

In instances like this, where Corona is adopting a v-ray feature (enmesh is another example, improved sky is another but from Corona->Vray) is the code re-written entirely? Or is it somehow copied across?

I guess what I'm asking is; will the procedural clouds in Corona be different than the v-ray procedural clouds? Do you guys make an effort to copy the features + usage completely or do you try to distinguish it from the vray features?

Just interested, ignore me if you don't feel like disclosing!

Title: Re: The most wanted feature?
Post by: TomG on 2022-08-04, 18:53:59
Render times are really good, because these are not true volumes in the 3D scene. Going from the experience on V-Ray, adding a few clouds makes no noticeable difference compared to an empty sky, but if you make it super cloudy and have ground shadows you may notice a slight impact on render times (still nothing compared to adding OpenVDB or VolumeMtl clouds though!) You can basically activate these whenever you like without being concerned about render time impact (of course, still waiting to test this in Corona myself, but I can't imagine it would be THAT different from the V-Ray situation).

not at all ;)

In instances like this, where Corona is adopting a v-ray feature (enmesh is another example, improved sky is another but from Corona->Vray) is the code re-written entirely? Or is it somehow copied across?

Could be 0 - 100% depending on feature.

Enmesh/Pattern was developed pretty much independently because of what the feature is - the major part of the feature is the infrastructure connecting it to the renderer. The pattern itself is relatively simple render-time instancing, but connecting it with everything else is tricky. No code reuse was possible here. Also the Corona version was finished at the same time as VRay, not after.

In case of clouds the major part of the feature was easy to adopt, so using VRay code here helped massively.

I guess what I'm asking is; will the procedural clouds in Corona be different than the v-ray procedural clouds? Do you guys make an effort to copy the features + usage completely or do you try to distinguish it from the vray features?

When adopting, the second team has the benefit of seeing what worked out and what did not, and adjusting it accordingly. Like with any other product - the second iteration is usually more polished.
Independent of this, there are always adjustments based on the individual product philosphies. In case of Corona, we ask how we can make it streamlined and easy to use. V-Ray team usually has to add more knobs for some specific edge case workflows requested

I like this. I guess it makes sense for Corona implementation to often come second when youre looking for the streamlined approach then.

Just putting it out there...Its been seven years since the first post (that i can see) asking for the IR window size to be lockable. It was said at the time (2015) by Maru that it was already planned.
It irritates me and causes me to lose time on a daily basis waiting for a previously clean IR window to re-render itself after moving the window and having it undock itself and resize.

Can we PLEASE get this much needed feature in V9? At this point it has to be the most posted feature request on these forums.

For this "New and better frame buffer", I hope it means being able to see albedo in the docked version, and to retain the rendered image when stopping IR :)

EDIT: and for this "Dedicated fabrics shader" it would be great to see some kind of fuzzy hair effect, longer hair than just a falloff effect of the current shader, something that is currently very hard to achieve without taking too much in resources.
Title: Re: The most wanted feature?
Post by: TomG on 2022-10-03, 17:00:55
Pattern should be very good at adding fuzzy hairs, without taking up too much resources (since the source geometry is only loaded once), if you don't want to wait :)

In many cases, yes. I was thinking about cases like the attached, when pattern wouldn't really work well and you need to use hair and fur; I always end up wishing you could add more tiny hair to each strand to make it look more fuzzy. Although an opacity map could work too. I don't know. Just saying.
Otherwise, I'm not sure what a dedicated fabric shader would be for.

Can developers explain at least is it possible to "convert" Corona into a GPU render engine, as there are so many Hybrid requests.
Do not get me wrong Hybrid enthusiasts, but I think that would mean rewriting the base code completely, meaning it would not have the qualities of the CPU Corona.
Taking example on Vray, it has been developing the GPU version for so long, and as far as I know it doesn't have quite some features of the CPU version. Meaning the current scenes would need to be converted and adapted for the GPU options, in which we would start complaining about some features that are not implemented like in some other engine (hint: it starts with F).
If that means crippling the current process of Corona in improving features or adding new ones, would that be feasible? Something that would get half results in both fronts, leaving no one satisfied.

I may be wrong completely, that is why a explanation would help in this matter as I am sure the team researched this possibility if they put it in the list of wanted features.

Cheers!

I think you've hit the nail on the head here, perfectly.

I know I've read from the developers themselves, many times in this forum, exactly your explanation for not making a move in GPU. Which I think is 100% fair and reasonable. No need to take steps backward!

Out of interest; what features do you think the aforementioned 'F' renderer is missing? :)

I haven't used it, but from what I've seen it is pretty good and can not say what is missing. I used it as an example for what we usually do in this forum, and what I saw in their group.
Do not like when the community turns salty and criticize other engines, like in the last time when Corona pattern was added they went mad that this is copying their blessed engine.
The next post is "Where CoronaSky, faster!!!" :)

I would think improving some features, trying to make a little faster IR and fixing some early following bugs is my suggestion/vote in this matter.
And also if it is possible to make an exclude option for Denoiser would be fancy in some materials.

Sorry to mods for wandering off the topic a little in these posts!

Feasibility of Corona going GPU was explained more than once already. You people just don’t listen.

Corona was made for those “less technical” users, yet devs decided to let those users be quite involved in the direction of development. That leads to unrealistic expectations from the community. not far from kids being allowed to drive.

I heard so many dissatisfied voices here over last three or so years. Not constructive critique but simple whining. Very much undeserved. Be grateful for being allowed to be involved and be mindful of most likely quite limited experience with software development.

Regarding hybrid rendering - who tried it? and of those who did - who claims that this limited use case feature is the next important step for Corona?

Post by: James Vella on 2022-10-30, 14:25:11
I agree that Vray GPU is missing quite a few features which is a bit of a let down. However in theory if Hybrid rendering was introduced such as how Redshift/Cycles has done it what's wrong with that? The way I imagine it would be if you have a GPU that you can enable to speed up rendering you click the button, if not use the CPU or both. That sounds great to me as long as all current features work. This also means you get to keep your render farm in case they don't have powerful GPUs for overnight stuff. That scenario sounds like a win/win to me.

I would say that in terms of scalability, GPU/hybrid rendering is absolutely the future of rendering. And those that dont embrace it in some capacity are at risk of being left behind.

I agree that theres reasons why corona isnt made or suited for GPU and its not happening any time soon in any major way. But utilising GPU power is without a doubt an important step for the whole industry.

Whilst it was made to require less technical knowledge, it was also supposed to not get in the way or be an obstruction to quality which it does beautifully. You shouldnt have to be a technician to be able to do accurate and efficient light transport calculations when you have a team of developers that really know what they're doingt.

There has definitely been some ridiculous entitlement on the forum in recent years leading to heated debates. I think engaging with the community is something the dev team has done really very well though and is part of the reason why i still champion the software to anyone thatll listen. Its made my job easier every single day for the past 8 years and being able to utilise coprocessing would be a great help for freelancers like myself who dont have render farms in-house but have a decent GPU thats sitting idle most of the time. Even passing specific things like volumetrics or caustics to the GPU would allow us to improve render quality without the time penalty. Though its obviously easier said than done.

As appealing as could be the ability to run Corona on GPU(s) and gain a (really) big boost of raw performance, I can understand the reluctance of the devs to port the engine to GPU :

Time to first pixel and responsivess on Cycles and Octane are crazy compared to CPU, so I would really like to see big improvements on the interactive rendering.

  • a CPU render engine code is almost universal. A GPU render engine is Nvidia only or you have to be ready to maintain no less than 3 other versions : OneAPI( Intel), HIP(AMD), Metal (Apple). I don't know the details but I guess that's a bit more work than maintaining just one render engine if you don't want to tie your user to one videocard brand ( and even just NVidia is two implementations, CUDA and OptiX).
  • you are heavily dependent on GPU drivers, and this is not a detail. Here how it goes for Redshift users for 6 months : Super slow redshift IPR and rendering (https://redshift.maxon.net/topic/42190/super-slow-redshift-ipr-and-rendering)
  • And finally, the small amount of VRAM available, even on prosumer models, does not fit very well the type of project that the typical Corona user has to deal with. And NVidia killed NVlink with the RTX 4XXX series without offering a true alternative, so either you're stuck with 24Gb or you bite the bullet and spend 5K+€ on a RTX6000. Even so, it's "only" 48Gb and like the gaming cards, no more NVLink too.

I think hybrid could the the ideal. Where you have specific features that run really well on a GPU, supplementing the power of the CPU. Volumetrics, caustics ansd displacement being three things off the top of my head that i can think of that will add significant render time to a scene at the moment.

If theres any way that any part of the most intensive processes can be moved off to the GPU, even partially, leaving more CPU free to deal with everything else. I'd absolutely welcome that. That being said i have no idea how linear the computational rendering process is or whether anything i just said is viable. But more speed is always welcome!

But, the VRAM used in rendering process, is completely different than the traditional RAM.
In 24GB can fit a lot of data that in the traditional RAM will occupy 3 times more.

In 2009 I had the privilege to be one of the first artists using the iray rendering engine. At that time, the GPU cards were having only 1.5GB VRam and look how many stuff was rendered with that "limited" memory! :D

Anyway, I am curious to see how things will evolve in the years to come.

My 2 cents - id love to see big improvements with Distributed Rendering.
Currently, its a nightmare.

I have multiple machines, and when i use the DR feature, it takes a few minutes for the other machines to kick in.  So when i try using it for an animation, by the time the NODES start rendering, the MAIN workstation finishes the frame and it all starts over again (parsing) and the NODES dont do anything but parse and prepare the scene.

Im not too sure what goes on under the hood, but if there could be a way it somehow gathers all maps/assets and puts them in a pool for all nodes to see so that it doesnt have to reload everything (if this is what is causing the issue).

In anycase, its a struggle and i invested more into NODES this year to improve my speed, but i havent been able to utilise it yet.

This actually sounds like hardware related. More like slow network speed and response time. Make sure, you are connected to nodes via Lan, probably using CAT7 cables and you are utilizing GBPS connection speed instead of MBPS. Improving your network connection speed should help with this problem.

So when i try using it for an animation

At every frame change, the slaves get a new scene using DR currently, and they have to load/parse it. So if one frame of your scene needs a rendertime of 5 minutes, has a loading time of 3 minutes, parsing time of 2, then DR slaves cannot contribute. Corona Dr is unsuitable here due to the current concept.

One feature I would really like to have in the upcoming Corona is Cryptomatte by Material. The current solution is too restrictive to be practical. Vray has the per-material function which allows for an optimal use in compositing.

Another feature that I feel is really missing in Corona is the ability to save the same render with different VFB settings. This would allow for two different exposure settings, providing better control in compositing without the need to render the same image twice.

Hey Chaos Team,
Could we possibly get a dedicated white balance picker in the corona frame buffer?
And Secondly could Bitmap/Texture Compression be Implemented just like how it works in Gpu renderers. Out of core is not really a compression method. Thanks

PLEASE! give some love to these
Speed of interactive rendering improvements specifically 25 (6.9%)
Parsing performance optimization (e.g. for animations) 29 (8%)

These are two of the most voted ones, i have already seen the trello moving for V11, Please don't leave them behind, that performance optimization has been delayed for years :(

+1 for parsing improvements for animations.
Every realease I'm disappointed that it has not made anywhere outside of "pool of big ideas" on Trello board.
No other feature will have such a direct impact on cost of animation rendering as this one could have...

+1 to parsing indeed. Already voted but seeing as it got some traction I wanted to chime in :)
+ also fixing corona bitmaps in material libraries so they don't freeze up max if you touch the timeline the very first time(Currently waiting 3-5 minutes at worst)

I'm sorry, maybe the link was attached incorrectly, this is the first post on the 8th page of the thread, there is an explanation with two attached images, you can find the word "overlapping". 

Without touching on the issue of randomization, I requested a simple scaling of the pattern for overlapping, this will allow you to create seamless weaves without a long cropbox setup.

I could be wrong, but it seems to me that this improvement is easy to implement in terms of code, but it will allow you to use the geopattern with such efficiency as never before

I will attach those explanation images one more time so you can find it

Post by: Vlad_the_rant on 2023-08-31, 23:32:54
I'm frankly baffled by the VFB improvements being among the least popular choices.
The VFB has been clunky and bugged since about forever, a rewrite in QT for it is supposedly in the works but what is the point of a yet another tiles map (and there are at least 2 I can think of off the top of my head - the regular tiles and the Bercon Tiles) when you're still going to have to fight the buggy and slow VFB to actually see it?

Cryptomatte? What the hell for? Corona is an arch/product viz renderer first and foremost and all the other uses are secondary (and that means all the VFX stuff you'd actually need something like comprehensive mattes for).

You are supposed to get a final image straight out of the VFB, saving you tons of time of compositing and screwing around in post. You want to do post compositing? Use Vray as THAT is its primary function and it's specially designed for VFX work with other uses being more of a bonus than a purpose.

GPU/CPU Hybrid? I understand that most who use Corona think their PCs are like toasters and have no clue on how neither software nor hardware either works or is made, replacing the whole thing if it breaks and calling on some bored IT technician to fix stuff when replacement is not an option, but it has been said many times over and I'll say it again:

To make Corona compatible with GPUs it would require literally making Corona over entirely, from scratch, to run on GPUs. This means years of work, and a whole legion of bugs for another year or so after before it actually becomes properly useful.

Again - you want hybrid rendering? Say hello to... you guessed it... Vray. Oh, and that took something like 4 - 5 years to get GPU rendering ALMOST on par with CPU rendering.


Sorry for the rant but it's disheartening to see so many not getting these things...



Title: Re: The most wanted feature?
Post by: sebastian___ on 2023-09-01, 05:14:18
I will try to give a reply to your points with either guessing or speaking from my perspective - which might not align with the arch/viz crowd.

I like the idea of getting a complete final image straight from 3ds max complete with everything correct looking like motion blur, clean DOF, smoke, mist and everything, and in post maybe only doing small retouching and color correcting, but that's still a dream at this point. We will get there at some point, but not today or at least not for most complex projects.

We have tons of renderers for 3ds max, maybe the most of any dcc, Corona is among the famous ones perhaps because of the ease of use or the quality of lighting and so on. I saw complex films, advertising and so on made with Corona, but Corona can be very slow for video or for very high res stills of complex scenes.
  Passes, cryptomatte and so on can be good tools to avoid re-rendering.

I got the message years ago that it's hard to code a renderer for GPU and it can have more limits than the CPU counterpart. But there are at least 3, 4 or more renderers which manage to be a hybrid - rendering simultaneously with cpu and gpu. I'm imagining that people look at these renderers and wish the same capability for their favorite renderer Corona.
There are some renderers which manage to produce an identical image regardless if you use CPU, GPU or CPU+GPU.

Plus as time goes by more and more people have very powerful graphic cards in their computer, maybe even 2 or 3. For different reasons, gaming, help with davinci resolve, Premiere, particle simulations and many other programs which increasingly demand more and more gpu power. So we have these cards installed in the computers - at our disposal, they produce a lot of heat, use a lot of power, and for nothing. Corona doesn't use them at all.
  At least it would be nice if Corona would use some gpu. A few years ago someone from Corona replied here that glow, bloom, glare and other post process effects could easily be calculated on the gpu. But I wonder if at least those are implemented yet in Corona ?

Bercon tiles, although I still use it frequently, crashes Max when changing setting or even moving the UVs in IR. Just FYI.
Also Bercon tiles seems to be unnecessarily complicated and I'm hoping to see a "Corona way" of solving the problem, which was always very intuitive and simple.

Yes I mean I would love to be able to use Vantage, but for that I need to switch to Vray. But I love the Corona renderer and think its sad that I forced to consider to switch to Vray to get fast gpu rendering for the less high quality rendering jobs that could be done faster. So, answer is yeah I would definately pay for vantage if I could have it with corona support.

Thank you for the reply! I'd love to hear from others too, so do please chime in :) While in development Vantage was free for a while, and I just want to be sure that people expressing an interest realize that has changed, as in order to consider whether or not to add that compatibility, we need to know that people are aware that it is now a paid product.

Post by: JoachimArt on 2023-09-08, 13:27:01
Personally I think adding support for Vantage would be a perfect way to integrate peoples wishes for GPU rendering, since that has been high on the list but is a humongous task to make. Because in many cases one doesn't need to render perfect unbiased path tracing for every job, with vantage support, one has the option to choose - so it would sort of give Corona that GPU feature. And perhaps it could have been added as Premium offer for a higher price to have corona AND Vantage same way you now have Phoenix. (for cinema 4D users that would have been a more appropriate package, since they don't even have Phoenix)

I'm pretty sure you haven't just heard people asking for it "now and then" since we've been asking for it all the time and everywhere. But it seems you guys don't want to make that move. Just Make a poll. Try to reach most people with it and you'll find out Vantage and GPU rendering are the most wanted feature.

I personally had to move back to V-Ray GPU/Vantage after getting a 4090 and the difference in speed is massive. It's just on another level. I do prefer Corona's more straight forward workflow and UI, but at this point in time that's all it has to compete. V-Ray development is way faster, GPU rendering is way faster, and now you have Vantage compatibility.

@Tom
I think it's true it would be best to have a separate survey for that. Personally, I can't imagine myself using it and it would take lots of corona team's resources that I'd rather see invested on other things. I don't do animations at all and I think it's the same for the majority of the userbase. Just a hunch.

I also think that a gateway to Vantage will be important in the future, this software saved me for a recent video, exceptional order, very tight deadlines. It manages to digest large scenes and it's quite surprising (no less than 16GB of ram gpu that said). It's the parsing time recalculated each frame in Corona that made me change engine for lack of time.

That said, having to go through vRay, take a universal converter, check all materials and compatibilities, adapt, export vrayscene: I wouldn't have the courage to do it for every project.

I don't think Chaos will change this new pricing policy; it brings it into line with Enscape, but the latter seems more complete to me. Vantage lacks a good batch rendering system with multiple camera setups to make the system truly versatile and usable in a pro workflow, otherwise it weighs down the process and wastes human time, it saves an enormous amount of rendering time, so we turn a blind eye.

Vantage is a software that I could consider taking on a monthly basis depending on my orders but not by having to pay vRay in addition. It is currently too dependent on vRay despite their version 2 which wants us to believe the opposite, it is this tunnel which is blocking it financially for me.

To summarize, if Corona could investigate an export in "vray scene" (Chaos/Cosmos scene in the long term, to make the whole thing more universal with its own definition of materials, mesh, etc.).  This would finally make it possible to create a Chaos ecosystem that can move from one software to another using this scene export.  Opening the doors to Vantage, or even Enscape in the future. I don't realize the work, it seems less complex than rewriting the Parsing or develop hybrid capabilites for Corona, a kind of ++ converter that goes in depth.

Post by: lollolo on 2023-09-11, 21:56:47
I also made a request for Vantage support, I think it would be very helpful in combination with Corona. Corona is super, but sometimes it would be handy to have something faster, for preview or animations with tight budget.
Would I be willing to pay additional for Vantage? Sure! I don't expect two render engines for the price of one.  But I'm a bit surprised how much it costs. As reference:
Corona 323
V-Ray 419
Redshift 274
Octane 240
D5 360

Vantage 599? More than any render engine above? I would have expected something between 300-400. 600 Seems overpriced.
It is the price of a very, very mature engine, with all the features you ever wanted. I don't know if this is the case... Maybe it will be in a few years?!
Would I still pay it? Maybe. Or I would switch to a cheaper engine. I don't know... What do others think?
Title: Re: The most wanted feature?
Post by: JoachimArt on 2023-09-11, 22:09:02
I agree, I think Vantage is overpriced currently ..I mean I would never swap out corona for vantage if that was the choice, so selling it for nearly twice the price is kinda crazy.. But, since I'm never going to switch to Blender and Eevee, this is the best option for "realtime" gpu rendering in max I have seen and I assume it will only get better - and eventually be able to replace a lot/most render jobs in the future. I would love for it to come as a bundle with corona rather than Phoenix, for 800 a year or something. In my opinion. But all in all I think its one of the best features Corona could add, and then just ditch the idea of a hybrid render.

And "willing to pay the extra $600 a year on top of the Corona subscription?" - that's an important point to let us know when chiming in for Vantage :) Thanks!

Same here,
We're paying for Vantage already even though we need to go through the hassle of converting everything from Corona to Vray. We do plenty of animations and Vantage is really handy to present drafts/previz stuff to clients.
We're pretty dissapointed that is has been taken off Vray Premium Subscribtion though. On the other hand this allows us to only rent it during months we actually use it.

Speaking on my own behalf, absolutely. We acknowledge that it requires more coding time, potentially necessitating an expanded team. Hence, it seems logical to pay extra in this context.

Post by: zaar on 2023-10-06, 09:38:11
Just chiming in here since your are talking about this. I've been thinking about making a more thought out post about my thoughts on V-Ray, Corona and Vantage.

I've been thinking about this basically since the merge. I've used v-ray since it was brand new, and when Corona got enough momentum many collegues wanted to switch. I was reluctant because I just felt I now had to great renderers on their own, but looking at them together, they we're both incomplete. What ever I did, I missed something from the other. I grow to prefer Corona for arch viz. But every now and then I get work that requires v-ray for certain reasons.

Paying for Corona + PhoenixFD and then having to buy V-ray + Phoenix (to get a floating license). I feel like I pay for Phoenix, cosmos and scans etc twice!

I want a Chaos Premium subscription that includes it all! Even Vantage. And this is probably very doable from Chaos side. But it leads to the problem of something that hsn't seem to be very doable or high on the agenda and that is cross compability. I don't want Corona UVWrandomizer and a V-ray UVWRandomizer, I want a Chaos UVWRandomizer that works everywhere. I understand that from a development point of view, this is much harder and slows things down. Not just because what ever map or function you invent, it has to work I many different places. And also the competition between the teams has been very good. First Corona UVW Randomizer was great, then the V-ray implementation was a little better, and now Corona has updated again to better. I see that it's difficult and has drawbacks. But from a customer and user perspective, I want my chaos stuff to just work with chaos stuff. And building a chaos ecosystem, I remember the CG Garage episode after the merge with Enscape, talking about how cross compability and unified ways of describing things was an important thing a head, but so far I feel I'm seeing very little of it?

I posted about this before, when I had troubles baking textures in Corona and had to switch to v-ray mid-project. If things were more compatible it would have been a non-issue. Just "get v-ray for that" and you can subscribe to it for just those months. And if that was the case you can even remove baking from Corona, and let it specialise on being the best cpu renderer for archviz.

And if this comes across as harsh or unpopular, just know that this comes from someone who cares a lot about these products and wants to keep using them.

Might sound silly but a way to lock the Frame buffer (specify resolution) for when using interactive rendering, sometimes its useful to be able to interactively render at the resolution you're going to render out of but also its somewhat tedious when moving the VFB and it adjusts its size and restarts to the process all over again.

I remember that someone seem to have already asked in this thread, but I can’t find if the request was logged

It would be very nice to get a blend-shader, I’m now doing more and more exteriors and fitting individual assets into the environment can be very time-consuming.

(https://i.ibb.co/1mVhr6y/corona-blending-shader-c.jpg) (https://ibb.co/W29qkt8)

Now, we can do this by using CoronaDistance, but if you want to do so - you need to create a Layered mtl each time for each object, that you want to organically fit into the environment. If a more complex material is applied to the ground, which already contains Layered mtls, the shader tree turns into a mess. Plus we can't get proper normal blending, CoronaRoundEdges Map doesn't work well in this case.

It would be convenient if, right in the “advanced options” section, each material had a checkbox that would enable mixing with environmental materials, without the need to change the material tree and add objects manually to CoronaDistance.

- this section could have a numeric distance/radius parameter;
- a map slot similar to the "Distance scale" slot in the Corona Distance map (there we could insert a height map from an object that we embed in the environment or some noise map);
- a checkbox for mixing normals, which will either use a separate radius or take it from the main distance parameter.
- texture coordinates can be projected directly from the parent (ground) object.

P.S. This will undoubtedly complicate the structure of CoronaPhysicalMtl, especially for the newcomers.
And in general I am not a supporter of the approach of a universal all-in-one shader for all use cases. So I would prefer to have an additional map (or a reworked corona distance map with the second "mode") that would contain all these parameters and would connect to a special map slot in corona physical mtl, if necessary.

You can use Corona AO instead of distance. I sometimes use this technique and it really improves object blending. I wouldn't say it's very time consuming or difficult to setup, but if it could be made more automatic, i'm all for that.

Yeah Normal Blending would be very nice. I've noticed with advent of high-res assets and real-time displacement, even Quixel/Unreal guys no longer use it much but it's such a nice thing to have in many other situations.

+1000 for this approach, One other thing that im missing is a BUMP Material just like Vray Bump material (NOT shader) in order to be able to better blend objects with its surroundings.

Just out of interest, why do you need a proprietary noise map? It seems to me that built-in procedural maps, third-party plugins and OSL ones completely cover all possible needs. I would rather prefer to have more advanced "advanced wood" map :D, since Corona is primarily a renderer for architectural visualizations in which wood appears regularly, and the built-in map and the OSL-option have some limitations and an insufficient number of parameters.

In general, it would be good, given the ideology of the engine, to add more “narrow” features for the archvis by processing them into the “Corona-way”. They could replace some of the outdated built-ins in Max, making the workflow more convenient for regular users.
A good example of such a narrow feature are clouds in the sky model, they are not needed in general for the render engine, because they can be replaced with background, proper HDRI or vdb clouds, but having them for quick results is so convenient

To me, performance improvements in interactive rendering could be implemented (perhaps restricting GPU calculations to interactive rendering?). Maybe it would help to have quicker initial feedback with something like Cycles "Denoise at first sample" (https://forum.corona-renderer.com/index.php?topic=38613.msg206795#msg206795)

Additionally, it would be nice to have improvements in VFB to make it more flexible in terms of resizing, similar to V-Ray's with features like clipping warning and such.

Hi, all the last corona releases had some user input from this board, is it no longer the case ?
Im sorry for Over simplify things but corona 12 dont seems that good for 6 months of development

New vfb skin (most of the code comes from vray)
scatter timm as checkbox (code comes from vray)
Curved decal (code comes from vray)
Scatter painter (code comes from vray)

We are left with corona specifics:

Unify cosmos and corona library (i guess this is mostly done by some artist re doing shaders?
Crypto by material
Material converter imporvements
Support sending scene to vantage (this is high on people minds, is just that corona is not that compatible with vray scenes and MATERIALS right now, and you guys did the blind eye to the industry trend of PBR / USD and all of that (conversion from corona mats to unreal is no existent in datasmith, USD is not even planned )

I really hope for the list to grow, i love corona for its simplicity, but the industry is moving fast, right now i feel that we are waiting 50%  of the time for the render to start, and the other working..

If I were you I would delete your post.
Criticizing programmers without knowing anything about programming or how long each thing takes...Doesn't look good on you honestly.
BTW, your website isn't working.


EDIT: I mean, other than version 7 that had "only" the new PBR material and it took a year from one version to the next...

Hi Lupaz
Hi Tom G, thx for the response, now I'm a little baffled, isn't chaos scatter developed for the two engines ? Does the corona guys need to re write every single line of code when the vray team has it working ? Honest Question!
Lupaz thx for the input man, i will no delete the post, it can answer some questions to someone else about development.
As for the website I'm no longer paying it, so its only behance, I'm working for another company and not doing freelance stuff these days.. you can check my behance here, https://www.behance.net/Arqrenderz1 I'm not the best but have a bit of experience in the field.

Post by: TomG on 2024-02-20, 22:04:06
Definitely no need to delete the post, I think all questions or concerns are valid, and are learning opportunities :)

Scatter is developed as its own product, so there is no writing code twice, correct. But Corona dev team members are involved in writing that shared core code (along with members from other teams), so when a new Scatter feature emerges, Corona dev time has gone into it. Then there is the unique code for each engine to have it show up in the UI of each engine, but that is indeed a smaller part of things (usually). Anyway, it does mean that the features for Scatter do involve work from folks on our team, which is why we list it as part of the Corona roadmap.

Hope that clarifies! Just means it isn't as simple as "someone else does the work, and we just copy it / write the UI for it" - we are involved in that development process too :)

Hi Tom G, thx for the response, now I'm a little baffled, isn't chaos scatter developed for the two engines ? Does the corona guys need to re write every single line of code when the vray team has it working ? Honest Question!

The company Chaos purchased Corona. Thats a business decision. From the programming side its completely different, its like comparing a Car to a Mushroom. Sure integrations can be made over time, and I'm sure thats the long term goal. But in order for the Mushroom get some wheels then you need to build it, same with the doors, engine, windows etc.

Its easier for one code base to understand what the other is doing by creating bridges along the way (what is a vray material, how do we convert it etc). But if you think you can just bridge something like the VFB (Frame Buffer) in a simple way, its not very simple at all. Everything needs to be rebuilt for each engine since nothing in vray is corona, and opposite. This is why there is a corona converter script, and other scripts that convert things, because the two engines are not the same, they have different ways of interpreting data, down to the most minute things. So yeah, Im not sure what understanding you have about how software works but this is like thinking if Windows purchased Apple tomorrow you could run all your windows software on Mac because Windows owns it. Not the case.
Title: Re: The most wanted feature?
Post by: TomG on 2024-02-20, 22:15:44
And yep, James is right on the other non-Scatter items. The VFB is indeed unique code for both engines, with different approaches tailored to the different needs of the user base (simplification: the "do everything for everyone" V-Ray, and the "specifically for achviz" Corona). Even with the VFB rework, Corona's VFB will remain distinct and different from V-Rays, by design.

Sometimes code can be shared or borrowed, sometimes algorithms can but need unique code, that can vary.

For curved decals for instance, there will be differences between Corona and V-Ray, which can be seen in the daily build. Corona allows for bending/curving in two axes (and simultaneously), while V-Ray allows for just one. So things are often not as simple as copying code from the other team :)

Hopefully with this, there will be understanding that care and development time has gone into these features as well as others, and so they occupy their own slice of the 6 month development time and are not 5 minute copy-n-paste jobs (to get back to the post that triggered the discussion, not replying to James here who I believe already gets this). Cheers!

Post by: TomG on 2024-02-20, 22:21:10
Oh and that is not to mention that there is ALWAYS unique QA time needed for each engine, even if it was possible to copy code - did it break something else, conflict with something else, does it work as intended? It is rare that implementing a feature, even one done in the sibling engine, is a trivial matter. (EDIT - but it's nice if that ever happens lol!)
