Re: Adaptive Environment Sampling on CPU and GPU

Adaptive Environment Sampling on CPU and GPU Ohoh, their solution, when compare to LuxCore Env. Light Visibility Cache, is a classic trade off between memory usage and quality: ELVC requires a LOT more memory/pre-processing to works well but it deliver better results ( if you use enough memory/pre-...

Re: LuxCore v2.3 proposed features

I'm seeing some nice and cool new 2.3 features being implemented at an unprecedented pace. Fantastic But let me ruin the fun a bit and step back a little.... I cannot use environment cache (autoportal) for preview, cause it is too slow to compute and runs out of memory in region rendering.. It drive...

Re: (Open)Subdiv and Displacement shapes

So I see maxlevel for opensubdiv but is this the only control?
How/when do you reach maxlevel?
Is this screenspace adaptive as in cycles (min edgelength by #pixels and maxlevel to clamp?)

Edit: ok sorry I just noticed the part about only uniform subdivs supported yet :)

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 adap...

Re: Shadow rays transparency for path tracers (aka hybrid glass)

Yes but I assume it will more useful once we have the transmission support added to Disney material. You wouldn't believe the crazy setups I sometimes have to do to please the client. And if the renderer allows for options like I requested here: https://github.com/LuxCoreRender/LuxCore/issues/148 O...

Re: Shadow rays transparency for path tracers (aka hybrid glass)

Good, so it's finaly possible to make thick glass panels and lightbulbs etc..

Re: LuxCore v2.3 proposed features

I do, always... renders are always way too blurry still. Can't get razor sharp pixels unless I fix it in post or render way higher resolution and downscale. Not sure whats the cause of this. I assume renders are too blurred after denoising. I doubt you can have blurred renderings with "NONE" pixel ...

Can be added sharpening menu with modern algoritm It could be implemented as an imagepipeline plugin: https://wiki.luxcorerender.org/Writing_an_Imagepipeline_Plugin luxcore renders are often somewhat blurry Try setting the pixel filter to "none".

Sharpening would be nice, luxcore renders are often somewhat blurry and I need to always sharpen in post.

Mmm, I forgot a probably interesting feature: some type of fast pre-processing for automatic variance clamping :idea:
I would like to see less and less pre-processing rather than another "step" to add :D I also don't trust the recommended values anyways.
