Light and shadow jitter between frames

I have a non-closed scene where there are 4 to 5 area light. When I render an animation, I find that the frame-to-frame jitters are severe. Is there any good way to avoid this problem?

Re: bake engine

Here it is. https://github.com/LuxCoreRender/LuxCore/blob/master/src/slg/engines/bakecpu/bakecputhread.cpp +279~285 Notice the: const Vector sampledDir = bsdf.GetFrame().ToWorld(localSampledDir); It works in local frame and, in the local frame, Z+ is always geometryN. :D :D :D I see, thank you.

Re: bake engine

In the code of bakecpu/lightmap, when calculating the next ray, why does the sampling direction not need to be adjusted based on the sign of calculation result about dot(sampledDir, geometryN)? Where exactly, do you mean the BSDF::Evaluate() ? Here it is. https://github.com/LuxCoreRender/LuxCore/bl...

Re: BlendLuxCore Development

Thanks for the reply. Yes this is what i get currently with dot. But my purpose is to use dot texture for flakes layer in a carpaint shader. https://cdn.dealerspike.com/imglib/v1/800x600/imglib/Assets/Inventory/D6/96/D6962FF3-67C8-4E48-9F0B-783BEA52D697.jpg I know the cycles voronoi cells texture w...

Found the problem. I was using forward-backward tracing. When I switched to backward-only, it worked fine.

Which points to a bug in the forward-backward processing I think.
emmm, what is forward-backward tracing? light-tracing + ray-tracing?

Re: Disney BRDF material

It's a "gimmick" basically, I find it to be useless to be honest, that's why I hope 2015 version with true SSS gets implemented rather sooner than later :) Where can I find the 2015 version's paper? I can implement it in Luxcore. Should be this paper : https://www.google.com/url?sa=t&source=web&rct...
