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)?

Oh, thank you. this is great

I want to export the scene on blender to .scn format. So I can render it with luxcoreui.
What should I do? Develop a new feature on the plug-in?

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...

Did you use denoiser?

Which points to a bug in the forward-backward processing I think.

emmm, what is forward-backward tracing? light-tracing + ray-tracing?

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&...

I can implement it in Luxcore.

Why Does Luxcore Support Materials Based on the GGX Model? Why shouldn't we ? In case you wanted to ask why "doesn't": current Disney material uses a GGX distribution. I transplanted Microfacet Reflection from pbrt to luxcore How ? Where ? What does mean "transplanted " ? and th...

I transplanted Microfacet Reflection from pbrt to luxcore and the results did not meet my expectations.
I'm using Trowbridge Reitz Distribution.
