Re: Adaptive sampling improvements

This is a bit on hold, since I am without access to my usual environment and getting OCIO to compile on my Windows notebook has been a struggle. However, I guess I could try implementing the BlendLuxCore part to enable better working adaptive rendering when using some of the current imagepipeline pl...

New image pipeline plugin: White balance

Hello, I've implemented support for a new image pipeline plugin to white balance the images after they've been rendered This should work just the same as selecting a white temperature on the Radiance group feature It works on linear space, so it needs to be put before gamma correction This plugin is...

Re: Adaptive sampling improvements

Hi, I am working on getting the convergence and noise tests to use arbitrary image pipelines. (https://github.com/Alpistinho/LuxCore/commit/9067f6492bcfa3b1199b7e962fd0b582c7dc99b2) I will try then to get OCIO integrated so we can replicate the Blender filmic tonemapping internally and get the adapt...

It is activated by default or something special is needed in blendluxcore for that one ?
It replaces the old code, so nothing is needed.

I don't think the difference is that big outside a few specific cases, so you might not be able to promptly see the difference.

Low discrepancy triangle light sampling

I have implemented a new technique for sampling triangles that should provide better results on them. This is based (copied) in https://pharr.org/matt/blog/2019/02/27/triangle-sampling-1.html The improvement should be most visible in scenes dominated by direct light. Please give it a spin and keep a...

Exactly. The question is, why ate they more than available and render still run.
If the stats are accurate, swap most likely. The performance would probably suffer pretty badly, though

Re: PhotonGI cache

I don't know why are you calling with SampleOffset+3 instead of SampleOffset, but changing the RequestSamples call to sampler.RequestSamples(PIXEL_NORMALIZED_ONLY, sampleSize + 3); Seems to fix the problem for me. After that it NEVER crashed again. BTW: I'm using the commit in Aug 10. If you use ju...
