Corona Renderer 5 for 3ds Max daily builds discussion.

*You can always get the newest daily build in the usual location: [link]*

[JViz]

already? awesome! lets go eh

[Ryuu]

as usual, it will take us few weeks before we start releasing v5 daily builds :)

Now that I've been able to render more shots with characters in it, I've been noticing issues with adaptability and motion blurred hair. Here is an example. If you guys want a scene, I'd be happy to upload one for you.

Sorry to hear that... We will definitely need a scene (however it can be simplified). Support is the best channel for this.

Hi,

Thanks for reporting this to us. I have your scene and we will investigate this issue.

Cheers,

Hi, guys, the displacement on corona layer material its behaving wrong, its ok for the first material but it gets all distorted when you add the second material, also if the second material has the same displacement as the first one

Can you please share a scene where this problem occurs? Also a screenshot of the wrong behavior may help in case we're not able to reproduce the issue.

[VASLAVO]

yes, the first is displacement active only n base layer, second layer off, the second is active on base layer but off on second layer, the third is active on both, as you can see only at the base layer the displacement behaves correctly.

[Njen]

I think it's hopefully time for all of the issues that the layered material has to be fixed :D

I am totally behind this. LayerMtl is so useful most people will use it at some point and sometimes a scene has lots of them, but it breaks apart in so many different aspects whenever REs or RE-Masks are used. It's high time it gets some love and fixes... also we ask quite some time for fixes on this one... please :D

The fact that only the base layer gets displacement and bump calculated makes it nearly useless in some obvious use cases I find. I would love for that to somehow work, so one could layer displacement, but I understand it might be an easy request, but not an easy task.

[shortcirkuit]

hey Guys - ive requested before but hopefully its gets looked at - for corona image editor - it would be awesome to have the ability to copy the image straight from the frame buffer (so we can copy and paste in photoshop for instance)

Hi, this is already implemented and will be available soon in v5 dailies. ;-)

[Dalton Watts]

Any hopes of getting "small" improvements like:

- show highlight and shadow clipping in VFB ( https://forum.corona-renderer.com/index.php?topic=23675.msg143917#msg143917 )
- In-camera copy camera settings (tonemapping & postprocessing) to render settings and vice-versa ( https://forum.corona-renderer.com/index.php?topic=22943.msg143921#msg143921 )
- Camera lister

Thanks guys!

[Creative Lighting]

Some improvements that we would like to see in Corona 5 :)

Lights, LightMix
- Option to save/load LightMix per Camera
- LightMix - "Swap" feature for colors, not just copy
- Color palettes for LightMix, option to save and load them back at anytime
- Right-click LightMix items to rename lights
- Support for negative light values in Standard 3ds Max lights ("painting with shadows" - like in scanline renderer)
- Compare different post-processing, LightMix with the VFB history (Corona VFB and CIE)
- LightMix - Add self-illuminated objects as LightMix items

IR
- Lock IR resolution

Toolbar, Lister
- List light instances as a single item in the lister

Corona Cameras
- Diffrent resolution and image aspect per camera

Other
- Inverse gamma spinner in Corona BItmap
- Noise level is sometimes inconsistent
- "Stats" tab in CIE
- Masking objects behind refractive glass
- Preserve opacity in scene material overrides
- Slicer/clipper - Ability to control the "inside" material (edge of the sliced object)

Thanks,
Nikos

[Feodor]

Corona Cameras
- Diffrent resolution and image aspect per camera

I use this script
http://www.scriptspot.com/3ds-max/scripts/camera-resolution-mod

[Creative Lighting]

Yeah, I have it as well :)

It's a great script but it would be awesome the Corona Camera to have it implement it.

Camera lister would be very useful as well, I forgot to add it on my list yesterday.

Hi Corona team
 
I saw on your roadmap that you've done memory optimisations (up to 87%) - are you able to elaborate on what that means specifically?  Like, if a job takes up 40gig ram, does that mean it would save up to 85% of the ram?  Main reason I ask as Im getting a new workstation soon and not sure whether to get 64 or 128 gig of RAM.  If such savings of ram occur across the board, then i dont see why anyone would need more than 32gig of ram

Its complete so is a daily expected soon?

Looking forward to this.

[Ryuu]

I would not base any buy/not buy decision on information like this :)

The memory savings are mostly in better handling of scene geometry, so if most of your memory is now taken by textures, you will not see much benefit from this particular optimization (although we plan to optimize texture memory usage as well).

From my experience, any additional RAM is never wasted. It will just allow you to make bigger scenes, higher resolution textures, higher resolution renders, etc. :)

And yes, we'd like to do the first v5 daily build quite soon.

is the 85% saving in geometry? if it is then well textures still take a huge amounts of memory that's your reference right there

[Ondra]

85% happens in specific situation where high UVW channels are used. Regular scenes can expect 15-30% RAM reduction, based on how heavy the geometry is. If you are using higher UVW channels, you can expect 50-85%.

I just rendered a 24000 pixels wide image, 128 GB were barely enough, and the 96 GB ram on my render farm were not enough the nodes crapped out. this is after deleting most of what I can live without in the scene. The image rendered for 10 hrs then backburner timed out had to restart so I tweaked the time out timing to be 7000 hrs but this time it crashed a couple of times. I ended up sending it in slices and it used up to 60+ GB ram but I was able to use the render farm.
I am looking at those new 32GB sticks that Corsair launched. you never know when a client will want a 6 meters high billboard.

Hi, I'd say that for 6 m long billboard is 10 000 px image more than enough. I always use 1/10 ratio for bb images. You never look at billboards from one meter.

[sprayer]

You never look at billboards from one meter.

Even more for 6 meter there is no such printer and such photo paper size for printing in good quality, so it will print on banner fabric on which cannot be printed with high DPI

Probably but I decided to take the money and not argue with the client. It took me 25 years to learn not to argue with clients, they know what they know.
he said people will be right against it.
I myself think the printer guy will lower the resolution and then print rather than wait for it to process.
Take the money boys it is better than being smarter than your client.

Just spotted 2.5d displacement on the trello. Cant wait to see some comparisons :)

Instant crash as soon as I turn on caustics in this scene

Some of the lights have excluded objects, some of them have caustics off anyway.. crash

Should I send you something?

Instant crash as soon as I turn on caustics in this scene

Just had the same (+minidump), crash in Corona_Release.dll, access violation. Scene created in v4.1, rendered in v5 current daily + caustics enabled.

Edit:
And after resetting settings scene rendered, but then when pressing "Stop" I got a Unknown rendering exception.

Maybe. Still investigating and trying to simplify. Another bad bad bug found which ist not exactly part of "Optimizations": Displacement gets calculated for hidden objects if they WOULD be visible in the view frustum it seems.


Good Luck

Edit: uploaded scene  "1564575655_v5-CausticsCrash-MixMaterial.7z". It's only one object inside :) Seems to be caused by a mix material.

Hi all, something is going on with the latest build here as well, I have a scene which is stucked at "Rendering initial pass" and everything is completely blocked.

Turn off the new caustics solver resolves the case. Is very weird as yesterday it worked fine while I was testing my setup but then I added some new elements in the scene and now is not!!! I am trying to find which elements produce this kind of block.

[Tanakov]

Not sure if its corona's fault buuut this never happend before I got the new daily so..

Scene is in Daily 5, my render node still has Corona 4.1.. ok ok but look at this light diference.

Light is not scaled or wierd in anyway

Im showing two different frames, but you get the idea.

Edit:
Same with updated version

Hi,

I'm not sure there is to much we can do about this. It seems that fbx in general is problematic and in this case it is most probably a limitation of the fbx file format which we don't have any control over.

Cheers,

Rowan

[PROH]

@rowmanns: The FBX exporter should report this during the process, not crash Max. So this (crashing Max) should be considered as a bug.

I did not manage to reproduce any problems with Layered Mtl + Caustics in the 07.08 daily. Can you please elaborate? A simple scene would be great.
Or maybe it's already fixed?

Update: ok, it is fixed. :)
If anyone wants to try it, it won't hurt though!

Hi, corona 5 daily crashes when conrona light mateiral is changed from emit light to dont during interactive render, havent tested on other situtation but here is the minidump, hope it helps.

[FrostKiwi]

Since the Nvidia Denoiser and High Quality Image fitlering are both on by default... do they now work together?
Since they used to be semi-incompatible...

[maru]

It's the same in V4 and V5.
For IR, HQ filtering is silently disabled, so that Optix can be used.
In production rendering, the same thing happens, but the user is notified about it. No compatibility yet.

[FrostKiwi]

HQ filtering is silently disabled

Ohh that makes sense.
If I disable Optix, is HQ filtering used? Or is it just always disabled?

[ihabkal]

Hi, corona 5 daily crashes when conrona light mateiral is changed from emit light to dont during interactive render, havent tested on other situtation but here is the minidump, hope it helps.

can confirm this, actually changing the material values causes crash too.

[ihabkal]

I also add that the corona camera Tilt and Shift tools are broken. see attached DR render. There is a possibiity that this applies to corona cameras adjsuted with T&S before this release and that you need to redo all your cameras if you install this one. zeroing out the numbers in shift for old cameras leads to a perfect vertical walls even though the camera is rotated 10 degrees down.

it also crashes if you

1. create a corona light (try a rectangle light)
2. start IR
3. lower the value of the light to 0.0 by dragging the small arrows next to the number. release then drag again above 0.0 then release. BOOM CRASH

Which version of the daily build are you using?

Currently I haven't been able to reproduce these crashes. Can you send me a scene? Instructions on how to do this are in my signiture.

Hi, the version we were using is the 08-07-19, and also can confirm the camera tilt error.

Hi,

Please can you provide the scene? It's really difficult for us to fix something if we can't reproduce it.

Thanks,

Rowan

Hi,

This will be fixed in the next daily build.

Every single one of my scene (by now 8th) crashes during IR if I play long enough with Corona Light.

Every single one of my scene (by now 8th) crashes during IR if I play long enough with Corona Light.

Reminds me of the joke: "Doctor, it hurts when I do this."
Doctor: "Then stop doing it"
Stop playing with the light for too long, I guess :P
[/offtopic]

I had like 20 crashes just today, sometimes after first change to single light in IR.

Reverted back to 4(Hotfix1) and everything is ok again. Half day of work and zero crashes again.

I had 7-29 Daily build, not the latest, and..was there any before the 29th? So the culprit is absolutely there.

Hi,

7-29 was the first v5 Daily build.

This issue has a high priority and we're working on it.

Thanks,

It Seems like the bloom glare crash has resurfaced. Using the latest daily build on my Xeon slave and when I come to save with bloom and glare it freezes again. Happened 3 times now. Saving as cxr seems to work,. Also had a freeze when clicking Ctrl+C this morning. Mini dump saved and sending now

We're with 4.1 too. The latest build is unstable and nearly not ready. One the flaws are the normal maps module; it's just not working.

Hello,

I have a question about Nvidia Optix, of course, its Nvidia but with AMD storming the front with both GPU's and CPU's do you have any information about their own Denoising solution? The only reason I still buy Nvidia is the amazing denoiser, but Im dissatisfied with the pricing vs overall performance.

Hi,

As stated in the daily builds guidelines they are not guaranteed to be stable, even though we try our best to ensure that they are.. https://coronarenderer.freshdesk.com/support/solutions/articles/5000570015

We are aware of the issue with normal maps and are looking into it.

Well, it seems that there actually is some AI denoiser from AMD. However we don't know any details about that and right know we can't unfortunately spare any manpower investigating it. We still need to focus on more pressing issues, like bugfixing and improving existing features.

And to be honest I think that we have too many denoisers already and since apparently everybody wants to have their very own AI denoiser, we need some better solution than slapping on a new denoiser every month.

[danio1011]

Has anyone else had the IPR stop updating with scene changes mid-session?  I haven't quite narrowed it down but it seems like maybe it's connected to dragging-and-dropping a material from the Corona material library onto an object in the scene.  IPR keeps running (I think) but in order to incorporate scene changes you need to stop and start IPR.  A restart of Max is required to get things going normally again.    Using Max 2016 and the latest daily.

You got that right, but still I thought Render Legion was friends with AMD after all that "Fire Render" thing.

Yes i do, but for me it only happens in one particular scene, where IR locks and the only solution is to restart Max.

Hi Rowan,
the scene is messy and old. I've noticed that if i delete almost everything from it, the bug won't happen, so it's most likely that some rouge object is causing the issues. I would like to find that object myself and send you for further investigation... i just need to find little bit of free time.

I would love to have some sort of UHD Cache frame skip calculation.something like "Every Nth Frame 'x'"
For cam fly through animation that will be great, I know we can do it separately limiting passes to 1. But to have this automatically would be great

Daily build 27.08.2019 problems I found on the start:
- Light Mix does not disappear after you start it in IR, stop IR disable render elements. (Error Unhandled exception, no crash)
- Render > Batch Render > View01 / CoronaCamera001 Seems like VFB is only rendering a certain area of the render (an effect similar to blow up), the render looks fine from "Render"
- Canceling a render started by Render to texture or batch render does not stop the VFB icon to spin or the passes to calculate.
- Closing the 3ds max after having all those problems, left a ghost window of 3ds max with only window bar visible and black inside that cant be closed nor killed by the manager.

At this point, I went back to 4.1

Hi, Daily build 27.08.2019 problems i found:

Hi Tanakov,

I have some further questions;

Which version of 3ds Max are you using?

- Light Mix does not disappear after you start it in IR, stop IR disable render elements. (Error Unhandled exception, no crash)

Do you have any further reproduction steps? Or is it literally;

• Start IR
• Stop IR
• Disable render elements
• Exception

- Render > Batch Render > View01 / CoronaCamera001 Seems like VFB is only rendering a certain area of the render (an effect similar to blow up), the render looks fine from "Render"
- Canceling a render started by Render to texture or batch render does not stop the VFB icon to spin or the passes to calculate.

Both of these work fine for me, do you have a specific scene where these issues occured?

- Closing the 3ds max after having all those problems, left a ghost window of 3ds max with only window bar visible and black inside that cant be closed nor killed by the manager.

This is really strange, I have not had this problem before. Can you capture a minidump from the process? Instructions on how to do this are in my signiture.

Lastly, are all of your drivers up to date? The nividia denoiser now requires a newer version of the driver to fucntion correctly. (418.81 or later)

Rowan

All,

A small PSA, before reporting bugs please please please can you read this document: How to Report Issues to Us

It really makes it so much easier for us to quickly reproduce, log and fix the issue when we have a clear description of what the problem is.

hi, i hava a question / report, after the latest 3dsmax 2020 update some features of 4.1 hotfix arent working as it suppose to, for example, you can see the hdri sky on viewport but when corona map select is applied the hdri seems to be flipped on the viewport but it renders ok, the seccond thing ive notie is that i cant seem to be able to see the map from a back plane with corona light material applied, have tried all combinations with no luck, it looks black, havent tested with daily build.

The second issue, can you provide some more details?

cant seem to be able to see the map from a back plane with corona light material applied,

Can you not see the map in the render or the viewport or both?

Can anyone please do anything about the VFB dancing all around in most times when I rneder while rendering or IR, especially when I have both my 4K screens on?it is very similar to

except many times fster dancing and flickering.

Hi!

I have the same exact problem! My colleague who has the same HW configuration hasn't any till now.

It's almost 3 months I occasionally have this strange issue but is very curious you're not having it with Corona but with another rendering engine!!!
Do you use the plugin Forest from iToo Software? I've noticed that I get thoses flashes and flickerings specially by using Forest.

I used to have this issue all of the time (along with the CPU downclocking randomly after a while - not related to thermal throttling, and FTH was disabled). The only fix was to disable any Intel Speedstep/C-state power saving options in the bios.

I am having it with CORONA not VRAY
I am havign it at home with Threadripper
At work I have intel it is fine I never have it
Corona has been doign this for almost a year on two different threadrippers 1950X and now 2990WX
If it was Vray I would go to Vray support
I am having it right now
basically every night I have to go through and waste half an hour to an hour on this
been patient for a year now
excuse the anger

Hi ihabkal,

I can understand the frustration but it is very difficult for us to investigate and fix something if we are unable to reproduce it.

Secondly, please can you create a topic on Bug Reporting for this, rather than flood the daily builds thread? As this is not specifically related to the daily builds.

I did what agentdark45 (thank you) proposed, cool'n'quiet is the AMD equivalent for speedstep, I dsabled it in bios and the system seems more responsive, I can switch from max while corona renders to other programs so smoothly now, but i only did small region renders I will come back if this doesn't work. but i tell you I don't mind spending a little more in electricity to have a very expensive 64 threads machine that acts like 64 threads!. this cool'nquiet did handicapp my system for a year now. it does feel more fluid.

Yes, twice. Complete uninstall before trying daily-2019-08-27 and daily-2019-09-16.
I double checked, that the old denoiser was gone and the installer did also redownload the denoiser.

When I downgraded to daily-2019-08-07 I did not reinstall and it worked.

Hi,

Do you have any other renderers or 3rd party plugins installed which could be using Optix?

Thanks,

Rowan

[FrostKiwi]

other renderers or 3rd party plugins installed which could be using Optix?

Nope, just corona.

Maybe it's something with backwards compatibility, considering this is the kepler architecture? This is the oldest supported architecture of optix after all....
Can I give some more indepth info? Some log or something?

edit:

ohhhhhhhh no.
Support for kelper is dropped with Optix 6.0 :[

All Users with a GTX 6xx or 7xx can go home.
The 780ti is still a very popular card and support is dropped, god damn.
Can you somehow provide both version? Download 6.X.X Optix for newer GTX cards and an optional download with Optix 5.X.X for Kepler (GTX 6XX and GTX 7XX and first gen GTX Titan) cards?

edit2: Considering how on my GTX 770 even a 4k denoise is instant, I kinda insist for Corona's optix to be backwards compatible :P

[romullus]

Nvidia doesn't want that you would sit on that old card for too long :]

[FrostKiwi]

That is just major league bullshit. I honestly don't get it. Optix performed so well on my card, why would you poop on your customers so hard?
I hope someone comes along to reset the GPU monopoly, like it happened with Ryzen crushing Intel's offerings this generation.
I'll go for an AMD GPU next time, just out of principle =.=

Hi team, do you have any plans to make some kind of connector to unreal engine, like vray has one.

[Ryuu]

Hi team, do you have any plans to make some kind of connector to unreal engine, like vray has one.

Well, definitely not in v5 daily builds ;) Other than that we don't have any plans to support Unreal engine in the near future.

[romullus]

Besides fully functional render to texture, what other support can be there? Just wondering.

Besides fully functional render to texture, what other support can be there? Just wondering.

Vray basically implemented 'itself' in Unreal. But I don't know...it's strange solution, the only benefit is that you can use Unreal also as 3dsMax scene manipulation alternative, it doesn't enhance the actual Unreal output, just enables you to output both (Vray raytraced or Unreal native) outputs.

As long as datasmith can interpret and translate every Corona feature correctly, there isn't much need from Corona devs to do anything. But I didn't test it.

[romullus]

Sounds interesting, but at the same time very limiting. AFAIK Unreal doesn't have any modelling tools, so you still need some dedicated content creation app.

About that "dancing windows" issue, which is not related to V5 dailies, but kinda is:
Did you guys report this in another forum thread, or over at support? https://coronarenderer.freshdesk.com/support/tickets/new
What's your RAM usage when it happens?
Do you have newest GPU drivers installed?

I didn't try it but I read you can bake the lighting with Vray inside Unreal which should be faster and better than the inbuilt Unreal GI solution.

[1equals2]

Posible solutions to the "dancing windows" issue:

I am dual xeon v4 user and experienced  this for quite a long time.
Had sent several scenes as well,  and when rendering experienced the following(regardless Vray or Corona): https://drive.google.com/drive/folders/1T4b851mAo25nYC4vSm9dmOGlub0RpZXW?usp=sharing
Managed to find temporary "silly"solution which worked for me most of the time --> switch user accounts couple of times, until 3ds max returns to proper behaviour.
Was doing this repetitive, laborious  taks for so long that stop paying attention.

In the middle of Summer finally found a  solution, which works, at least in my case - update to win 10 1903. Was using 1803 prior to the update.
Downloaded latest Nvidia drivers, removed the  windows ones, and installed the latest manually, Not via the Nvidia Installer. Actually I was not able to properly install Nvidia drivers with their automatic installer prior to manually doing it.
After doing those two ---> no more flashing, flickering, etc, or switching between user accounts.

Upgraded RAM  in the meantime, but believe the flashing was more of a software compatibility issue.

[The Pixel Artist]

Did you try a complete uninstall and reinstall of Corona?

Yes, twice. Complete uninstall before trying daily-2019-08-27 and daily-2019-09-16.
I double checked, that the old denoiser was gone and the installer did also redownload the denoiser.

When I downgraded to daily-2019-08-07 I did not reinstall and it worked.
tl;dr recap:
Newest Nvidia Driver -> "Error, expected Optix 6.0.0, but you have 6.5.0"
Driver 418.81 -> "Error as posted here"

I'm also the owner of a GTX 770 and having this this exact same issue today after updating to daily-2019-09-20 from daily-2019-08-27.

I did try uninstalling it and went back to the 2019-08-27 build, but same problem still.  Optix seems corrupted now.  I then did a windows restore point from yesterday along with a full uninstall/reinstall of corona and still the same problem.  I seems I've really screwed up by installing this latest daily build!!

I'm going to try uninstalling graphics driver next and see if I can reinstall a previous Nvidia driver.  Fyi, I'm running Win7 Pro, using 3ds Max 2016, and have two GTX 770s in this machine.  I did update my graphics driver a couple days ago to the current 436.30 version and but everything was running fine until I updated to daily-2019-09-20 in morning.

I'll also mention that I do also use Thearender for Sketchup, which does make use of Optix as well.  If that makes any difference or not.


Update:  Well, fully uninstalled Nvidia graphics drivers and went back to 436.15 version along with reinstalled daily-2019-08-27 and still same error!  Nvidia de-noising is completely broke and I have no idea what to do at this point.  Any help would sure be appreciated.

[romullus]

@The Pixel Artist, i'm affraid i have bad news for you, apparently Nvidia has dropped optix support for your card: https://forum.corona-renderer.com/index.php?topic=25036.msg156254#msg156254

I did read that, but what I don't understand is it was working fine before I installed daily-2019-09-20 and I already had the latest 436.30 driver installed.  I also just checked Thea and it's Optix denoising is still working fine.

So, is it Nvidia or Corona that is dropping support for older 700 series cards?  What exactly did daily-2019-09-20 do to break things and what files maybe need to be removed to get the previous daily-2019-08-27 building working again?

Update:  Just FYI, I was able to get things working again and back to the daily-2019-08-27 build.  I had to uninstall Corona again and then manually delete every left over Corona file/folder I could find on my system (you guys really leave a lot of files after an uninstall).

I also deleted the OptixCache files found under ...Roaming/NVIDIA/OptixCache.  Then installed Corona 4 HF1 and everything was working.  Then update my graphics driver back to 436.30, updated Corona to the daily-2019-08-27 build, and still working fine.  Obviously not going to be installing any new daily builds for a while.  I do hope you guys find a way to offer backwards compatibility if that is the problem.

Update 2: Nope, I'm wrong, it's not working with daily-2019-08-27.  Forgot I had it on the Intel denoiser when I first opened daily-2019-08-27 and hit render.  So still broke with 5 dailies.  But Corona 4 HF1 was work ok.  Really sucks too as Ver 5 was really rendering my scene much, much faster it seemed.

Nvidia released Optix 6.x.x, this version dropped support for the kepler architecture (GTX Titan 1st gen, GTX 6xx and GTX 7xx).
The Corona Team probably missed this and updated corona's 5.x.x version to 6.x.x, killing support.

Now it's up to the Corona team to either detect the presence of a kepler card and / or allow an option download for the 5.x.x version of Optix or just stick to Optix 6.x.x exclusively and make me a very sad panda :[

Yeah, that's unfortunately to read.  I'm certainly due for an updated GFX card, but was really hoping hold out a bit longer. I do hope the Corona team can provide an alternate solution as you've mentioned.

In the meantime, I was able to go back to the daily-2019-08-07 build at least.  That must have been what I was actually using prior to updating to the 9-20 build.

[rowmanns]

Hi,

I have discussed the GPU compatability issue with the new version on Optix with our dev team.

Unfortunately for people with Keplar generation cards we will not be rolling back to Optix version 5.x.x. For the time being we will be sticking with Optix version 6, and at somepoint in the future probably moving to Optix 7.

We are going to look into a better way to detect what GPU is in the system so we can check if it is supported by Optix and provide a more descriptive error message.

I hope that this information is useful, and I'm sorry for the inconvenience that it has caused.

Thanks,

Rowan

[FrostKiwi]

Ahhh, shucks. Progress before compatibility I guess. Either decision is a good one :]
Just FYI, according to the Steam survey, the 750ti is still in the Top 10 most videocards used.

Curious to know more about new displacement mode. Does it has some limitations compared to the old one? I did super quick comparision test and found that while 2.5 mode offers impressive speedup, RAM savings and has more details, it also shows quite strong artifacts all over the place.

Hi,

To me it looks like the displacement is much finer with the new displacement enabled rather than artifacts. But it is a little bit difficult to tell.

Would you be able to provide me with the screen size (px) you are using for both the new and old displacement? And if possible would you be able to send over your scene?

Cheers,

The artifacts are best visible when you alternate between the pictures - look for dark vertical lines in "displacement-new.jpg".

Render settings were completely default, it's just a plane primitive with Corona material and procedural noise in displacement. I didn't save the scene, but it should be very easy to reproduce. I'll try to make some more tests later and see if i'll be able to get more pronounced artifacts.

Edit: here's more convenient comparison: https://cdn.knightlab.com/libs/juxtapose/latest/embed/index.html?uid=781777ee-e444-11e9-b9b8-0edaf8f81e27

Hi, can you show us how your mesh topology looks like before displacing?

[romullus]

It's default plane primitive with 4x4 segments, not even converted to mesh.

[Feodor]

Very best new corona displacement!

[FrostKiwi]

Does 2.5D Displacement fully replace the old method?
Is there any reason or scenario to use the old one except compatibility to old scenes?

nice. i have a dumb question. is there any way to have it update the resolution in IR when you pan/zoom? i usually go a frame forward and back to update. thx

[romullus]

It looks that new displacement has much worse quality at the distance, compared to the old one.

Can we have dedicated displacement playground topic please?

[romullus]

Also it appears that faces at shallow angle from camera, has somehow incorrect shading.

Are you sure? To me it looks like your examples shows the same behaviour, it's just my lighting is more contrasty and issues are more evident.

[Ryuu]

We'll be releasing few optimizations and bugfixes for the 2.5D displacement in next daily build (hopefully today).

Romullus, could you please upload the scenes for testing? We can't really get much useful information just from the screenshots without knowing what settings did you use. Did you set the same pixel size for both displacement methods?

So why is he doing this? :(((((

[Frood]

This happens if you still have old Corona/RenderLegion/ChaosCz DLLs in your max root directory. The latest daily installer should fix this. You can also delete them manually (all Legion*.dll and Corona*.dll, and ScatterCore.dll).


Good Luck

[Fluss]

I just installed the latest daily and I have to say that I love the new displacement. Thanks for that! It was a long-awaited feature and it was worth the wait. There is plenty of details, and RAM usage drop is quite noticeable.

That said, the only drawback that remains is that this is still heavily impacted by surface area displayed (especially in world unit, for animation purpose). Combine that with geometric texture modeling ( http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.127.3226&rep=rep1&type=pdf ), which is, I guess, the paper used for Fstorm geo-pattern (this paper is an updated version of the previously posted one in the initial displacement discussion thread), and you would get the ultimate solution. Displace one tile, conform it to the base mesh -> Full details, slow memory footprint. Of course that wouldn't work with XYZ procedural maps, I get it. But that would still be a really welcomed option for tiled bitmaps.

Any help on this issue ?

Sorry for the delay! Next time please remember that you can contact us here - https://coronarenderer.freshdesk.com/support/tickets/new
Support is the more "official" communication channel compared to the forum.

Try this:
Go to your 3ds Max installation directory (e.g. C:\Program Files\Autodesk\3ds Max 2020).
Use the Windows search feature.
Enter the following one by one and search for those files:
Legion*
Corona*
ScatterCore*

If anything is found - remove those files. Remember it is best to move files to trash bin instead of removing them completely, so that you can restore them if needed.

Once the cleaning is done (i.e. after you have removed all of the above files from your 3ds Max folder), try installing the newest version again.

If that does not seem to help, please contact us using the link I shared above and if needed we will have a Team Viewer session.

[bluebox]

Thanks for getting back Marcin.
I purged all Corona files using Comodo programs manager (monitors what files are installed and where during program installation) to make sure nothing is left, so no registry entries etc. were left.
Then I did a clean install of RC5. Installer reported that the installation was successful but the problem remained. The exact same error on max open pops up and Corona does not work.

I tried installing it manually but to no success.

Any idea what else I could try ?

Turned out that you need to have your Windows 7 updated.

Thing is that this crappy MS installer won't install a certain update if you havent installed the one preceding it. It will just tell you that your computer is not eligible for the certain update you are trying to install. This might lead to an assumption that the machine is up to date.

If you strugle with the problem and you don't have any old obsolete files lingering on your drive install the following in the following order nad you'll be fine:
-Service Pack 1
-KB3020369
-KB947821
-KB3125574

Good job on the release guys. RAM savings are noticeable, overall feeling is more responsive and although not properly benchmarked we are under an impression that the scenes render faster.

If Corona crashes you should include the minidump in your post and maybe give some info on when it crashes, that's the second best thing you can do when reporting problems, besides the all caps text of course.

Edit - realized this sounds a bit aggressive, not meant to, but really try to be more descriptive so the devs have something to work with...

+1 for this.  Lots of times I'll create more instanced lights in the scene and just use the 'Setup' button to add them back into the appropriate Render Element.  This new approach would require more work for sure.

Ive uploaded to freshdesk ticet 178977, i cant seem to find the especific error, i know its related to proxys because at some point changing the maps, ajustint materials or selecting/moving the computer crashes, did the same process on different machines with crashes all the time but not always the same thing (some times after adjusting the materials with interactive and sometimes after finishing and then selecting ) also notice that on some proxys the keep in memory option was on with point cloud, this proxys were made with v5rc2, ive uncheck this thinking that maybe this was the issue but no, it crashes, ive revert to previous last night, not sure if my scene works for you as a reference but i will manage to select the proxys with textures today.

This is the first error message I received in the middle of rendering and the render operation stopped automatically. The scene I was working on was low poly and I think this is a bug for Corona 5.
Thanks

===== Error(3) =====
Bad allocation Exception!
Corona Renderer ran out of RAM an was unable to allocate memory it needs for rendering. This can be caused by rendering too big scene with not enough RAM, or an internal bug in Corona Renderer. Contact our support for more info.

It's usually not a bug :) The only way we could tell is to see the scene itself, or at very least a render of it to see what is in the scene - you can send the scene via private uploader and see the info we need for a bug report (such as which host software, which OS, which Corona version etc) at https://coronarenderer.freshdesk.com/support/solutions/articles/5000524006-how-to-report-issues-3ds-max

Things that can use a lot of memory are things like high res texture maps, lots of displacement, lots of scatters, etc. all of which might appear in "simple" scenes even if they are "low poly"

I noticed the crown does not behave stably during rendering, different scenes at different times can crash max without warning. This has not been observed before.

We'd really need more info - and the beauty of a crash (the only good thing about a crash) is it produces a minidump that says just what Max was doing at the time. For any crash, the best thing to do is send that to us (see https://coronarenderer.freshdesk.com/support/solutions/articles/5000524006-how-to-report-issues-3ds-max). Often it can help to send the scene too, both can be sent via the private uploader - but at very least the minidump would help. Unfortunately, with "Max sometimes crashes on some scenes" there really isn't anything for us to look into and diagnose :(

Have you tried disabling the adaptive light solver? (Performance tab)

Will try.

UPD - it worked, need scene or it is a known issue?

Hi since updating to RC2 I cannot use DR any more. The slave isn't found by the master PC when searching in the DR dialogue settings...

(I updated to RC2 but had loading issues, so I also did a clean install and updated windows 7, as mentioned above).

Any ideas how to fix this?

Hi,

Are there exceptions set in your windows firewall?

Thanks,

This happened to us in Corona 4 as far as I remember. Although searching for slaves did not work, they rendered fine if you just added their names manually before rendering.

Hi, thanks. I did this just now. It seemed to work....

However, I tested it in a fresh 3ds max file. Corona found the slave right away. When I open an older working file for a current job and try to search for slaves in this file, nothing comes up... odd behavior!?

You're right... this does seem to work fine. Thanks (again!)

@bluebox and @aaouviz,

Am I correct in assuming that you are both running Windows 7?

Thanks,

Yes, you are correct. Though, to complicate things; my slave is running Windows 10 while my master is still on 7

Checking this right now.

The first thing is successfully reproduced - "manual update" option does not seem to work as expected.
But I will need some help with the second point. Can you please explain what exactly is happening? I re-loaded a scene, and the scatter was there. I did not have to delete it and re-add it. Can you provide simple steps how to reproduce this?

Thanks!

Hi,

Would both of you be able to send me over a scene where this is happening? So far in my tests this seems to be working as expected.

Instructions on how to send us a scene are in my signiture.

Just tested a few scenes and the problem no longer exists. Slaves are detected fine on Corona 5 RC2.
We started adding them manually when we first encountered the problem and continued to do so up until now because we lacked time to troubleshoot.
Will remember to check every scene for the problem. If we find any where the problem persists we will send it over to you guys for investigation.

sorry I was unclear - I mean that Manual Update is not working
by the way what is maxscript expression for the cscatter manual update?

Ive uploaded to freshdesk ticet 178977, i cant seem to find the especific error, i know its related to proxys because at some point changing the maps, ajustint materials or selecting/moving the computer crashes, did the same process on different machines with crashes all the time but not always the same thing (some times after adjusting the materials with interactive and sometimes after finishing and then selecting ) also notice that on some proxys the keep in memory option was on with point cloud, this proxys were made with v5rc2, ive uncheck this thinking that maybe this was the issue but no, it crashes, ive revert to previous last night, not sure if my scene works for you as a reference but i will manage to select the proxys with textures today.

This should be fixed in RC4. When it is released please can you test and see if the crashes still happen.

RC2
coronascatter update is not working
need to delete and add again to apply scatter on or reload max scene

This is also fixed in RC4.

Thanks.

Has anyone else experienced a crash when hitting 'Copy' in the VFB with the latest builds?  Using Max 2020.  If that's not a known\fixed issue I'll try to get a minidump, happens to me about 2x a week.

Hi,

Please could you send over a minidump from this crash and if possible a scene where you are experiencing this crash.

EDIT: Which Corona version are you using?

Thanks,

Really can not wait to install the new version!

Hi,

We're working really hard on it. It will be released when it's ready.

However this thread shouldn't be used to ask for timescales, this thread is to discuss the new features and possible issues with the V5 daily builds.

Thanks,
