Re: Adaptive sampling improvements

The adaptive sampling is used, the stochastic nature breaks this and the values uses vary across passes and somehow this leads to a worse sampling distribution. Ok, so you have just draw the random numbers even if you are skipping the pixel :idea: This should be fix the problem at a trivial cost of...

Re: MaxLuxCore - 3ds Max Integration for LuxCore

Nice done Tao. Will also be very good if you post here also , just a way keep the Hype generator turning :D : https://blenderartists.org/t/luxcorerender-v2-2/1148794/146 Sure, Thank you to point it out. A 3ds Max forum may be even more appropriate (after all, BlenderArtist is a Blender focused foru...

Re: LXS volume problem

Yes, volumes are just ignored by LXS parser. I will check if the support can be added with a reasonable amount of work.

Maybe it should be renamed to "Diffuse reflection color"?
Yes but use "Diffuse transmission color" label too, I mean, they are symmetrical.

Re: Adaptive sampling improvements

It makes the rendering noisier again and the distribution for an arbitrary pixel I chose looks random and not Sobol. But this is very strange is like saying that the this sequence of a0-aN: rngGenerator.init(1); a0 = rngGenerator.floatValue(); a1 = rngGenerator.floatValue(); a2 = rngGenerator.float...

Re: Matte Translucent Material Node

The logic is (or was, like B.Y.O.B. wrote, this stuff has its root in code written 10 years ago): one is a scale factor used when light is transmitted and the other when it is reflected. "diffuse" would be a bit generic/confusing because light is always "diffuse", both when is transmitted and when i...

Re: Adaptive sampling improvements

I am not 100% sure about what is causing the issue, but as you can see on the samples distributions I've posted, the current solution is making Sobol more like Random. In theory, a sequence of (pseudo)random numbers is the same of a sequence of random numbers but I would be very suprised if the pro...

Re: Adaptive sampling improvements

Your code will produce duplicate samples on multiple GPUs and when using CPU+GPU (so there is a lot of wasted work). You need to use "seedBase + pixelIndex". You can't also call rngGenerator.init() for every samples, the overhead is too high (check the code), your slowing the rendering too much. Fix...

As I suspected, there is something wrong.
Note: before yesterday, Random/Sobol where still asking for Convergence AOV instead of the new Noise AOV so adaptive sampling was just disabled by default (because Noise AOV was not allocated).
