[Max] Feature Requests / Re: The most wanted feature?

« on: 2014-06-13, 06:02:41 »

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"

Thanks for your simple explanation Deadclown! I Hope this feature could be implemented.

If I understand this correctly you would like to have some clue during rendering to know how long will it take to get to a certain number of passes?

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?

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

And what about adding a feature which calculate or evaluate the "noise amount" in order to have an idea when the image is clear enough to be considered "ready", instead wait for long time renders?

For me, there are too many distractor elements on the table

also, I woul suggest to use DOF

Work in Progress/Tests / RESTAURANT PROJECT WIP

« on: 2014-05-28, 18:46:56 »

Hi guys

those are some test from a grill and bar restaurant we're designing.

critics are wellcome, raw images, all default values

1600x900
1.30 hr each
i7 3930k
16gb ram

ps. I have problems with light coming from counter, lower intensity (0.045) produces a flat grey plan, so I decided to use .05 and even that it burns the scene

thanks

Wow! Did you start with corona materials, or used the converter ?

I second that...

Did you used a Vray scene?
everytime I try to convert a whole vray scene, some materials got weird

on the other hand, changing one by one, would be a headache

Very nice images!

however your rendering times are too high for that resolution

Three grass shots done with Corona, promo material for my new Grass Generator script.
Everything was scattered using Corona Scatter.

vey nice pics man!

is it really cool from you to share your script as a free tool...
lets try it!

First endevour in Corona.  Love it so far, very easy to set-up and good results straight out of the box.  The building I saw recently on Domus, the paving is from a Foreign Office Architects coastal park using Railclone.  Cant wait to play some more...

very nice exterior floor, its only a texture? can you share i please?

Hello guys

First, I want to thank Rawalanche for those value tips, not only for me, but also the whole community
I will try your sugestions and post results nex week

Sorry for writing in capital letters, didnt want to be rude.

Just two more questions:

-concerning about albedo value, what do I have to change? difusse or reflection level?
-concerning about mergin objects to scene: do you suggest to re-make all materials, one by one... :S ?

ps. I start the scene from scratch, I just convert the plants and the vase. but this concrete wall is getting me crazy!, as well the strange behavior on those converted materials.

[Max] General Discussion / Vray user (almost Ex) , first impressions, troubles and suggestions

« on: 2014-01-18, 00:08:10 »

Hi guys

First of all, I want to thank the corona developers for such impressive rendering engine, really nice results in a few clicks!

I'm an intermediate Vray user, but in this two days I gave myself the opportunity to try Corona, and get easily involved, after looking the galleries with user's works, I guess it's time to move on...

I share with you my first test image for a WIP scene, very basic, but I would like to improve with your opinion ans suggestions, as well to ask some questions:

Corona was set to default values, except for

-LUT Gamma, enabled to 2.2
-Exposure: 9
-Highlight compression:30
-PT samples: 1024 (I read somewhere it can improve image quality)

MATERIALS

1. I just import some vray objects and convert materials with DeadClown's Advanced Corona Material Converter (http://forum.corona-renderer.com/index.php/topic,126.0.html) but I noticed items must be un-grouped previous to convert them, is a bug?
once converted materials lost specular levels or difusse maps are not correctly shown. please look at the plants

LIGHTS

2. Is there a way to hide the "solid volume" from corona lights? I mean, is kinda annoying to add some lights on windows and then get a solid volume which doesnt allow me to see thru the scene. Something like "wired" or non-solid light?

3. It makes me wonder: Is it really needd to add some lights on windows or spherical lights for interior scenes? at the end I just used a HDRI map as only light source.

CAMERAS

4. I love the option for correcting white colors with color maping post process in real time, but some times, depending on lights sources I have to change those values each time I need to get a new image, also, by doing this way, I will not remember the settings for each camera :(.

Plase add something like vrayphysical camera, in order to control DOF, Exposure, Highlights, contrast WB and so on. Please add the option for controlling those values on camera while rendering too, its a cool option!

OTHER

5. I set the same rendering time from my vray scene in order to compare image quality. As you can notice, Corona image seems to be more "blurred" at background.
There is away to improve or change Antialiasing? how can I clear noise?

6. I use the VFB + plugin (http://www.scriptspot.com/3ds-max/scripts/vfb-a-feature-rich-extension-to-the-3dsmax-frame-buffer), wich adds the option to load image files to compare with a slider , and also a filmstrip where you can see and "rescue" a previous rendered image. I similar option for Corona will be really nice.

Thanks!
