Re: LuxCore Vector Displacements
In Blender 2.81 they improved Cycles behavior: https://wiki.blender.org/wiki/Reference/Release_Notes/2.81/Cycles Adaptive Subdivision Cycles adaptive subdivision now stitches faces to avoid cracks between edges, that may be caused by displacement or different materials. https://wiki.blender.org/w/im...

Re: PhotonGI caustic cache re-factoring
Light tracing (or the cache) is used only "under" the sphere because the caustic is only there, over the sphere, normal path tracing will be used and your light source is very hard to find for a path tracer: just render with normal path tracing to have an idea. Yes, I know this, and it do...

Re: LuxCore v2.3 proposed features
If Bidir have to exist it need more love... BiDir must exist (and needs solution for SDS) to be the full featured "holistic" reference renderer. Path Tracing with Light Tracing and PGI caches is good for the most scenes, but it's overly complicated and still doesn't cover complex cases, l...

Re: PhotonGI caustic cache re-factoring
I prefer unbiased solutions, but in this case I think so too, that radius reduction isn't useful.

Re: PhotonGI caustic cache re-factoring
Are you sure that caustic cache works with volumes?
It didn't seem to me in my scene, so I made a simple test case.
BiDir + metro: PT Sobol + Light Tracing: PT Sobol + Caustic Cache:

Re: PhotonGI caustic cache re-factoring
No, no, I will still add an option for "use_caustic_cache_only_for_SDS_paths" so you use PATHOCL + Hybrid rendering + SDS Caustic cache to get the best of all modes. From the UI point of view it should be just a combo box in Blender with: 1) path tracing 2) path tracing + light tracing 3)...

Re: PhotonGI caustic cache re-factoring
I did some tests, and some caustics don't wanna show up with caustics cache.

Re: PhotonGI caustic cache re-factoring
I have re-factored PhotonGI caustic cache to use Vertex Merging (aka SPPM in the specific case used only to render caustics)... Looks very promising, though we've believed this already several times. (Sorry, didn't mean it! :D ) Questions: - Could the radius be specified in pixel space? It would be...
