Added the support to OpenCL for PhotonGI caustic cache update. Maybe I'm stupid again, but I don't get it to work. From Blender, where PathCPU + periodic cache works, I get mostly crashes when I try with OpenCL. When using standalone, again PathCPU updates but PathOCL crashes or renders without upd...

Are you sure? In my tests it worked in Blender, although the console messages indeed do not appear. New test scene works, the reason was this: Also the updating happens one sample later as specified: If I want cache updates at sample 8,16,24,32... I have to choose 7 as parameter. This is normal, th...

Thanks B.Y.O.B. for quick Blender integration! Only it does not really work yet: Cache update does not seem to happen as also indicated by console view which shows no entries during render. When exporting a binary and rendering with LuxCoreUI there is the code line (path.photongi.caustic.updatespp) ...

The size of the distant light was just hardcoded to 10 in the filesaver code. I fixed it.

Wow thanks for instant fix, you guys are the fastest ever!!

I got this scene to render pretty clean with OIDN under 12 hours, seems to even work with classic BiDir. With multi scattering enabled and russian roulette disabled, i was enable to make 1 pass to take 2500 seconds (bidir 64/64 x BiDirVM 256) :shock: Multi off and russian roulette on, i got nice cl...

I have just tested the new cyclic caustic cache with the latest builds of v2.2beta2 and my causticcube scene worked well with sunsky in Blender and standalone but when changing sun to distant and sky to flat color the LuxCoreUI render suddenly looks very different with overblown lighting. Here is th...

I have two ideas how to make PGI cache (more) unbiased. ... 1. Cyclically re-generating the cache I added the support for periodic update of the PGI caustic cache to PATHCPU :idea: Ha! Team Genius at work! Great solution, way better than caustic merge radius. Already tested and it works well on my ...

Border render with 130 000 samples - BiDir SDS-paths done by camera rays finding the area lights without light rays.
I wonder if Corona-style guided path tracing could improve this?

Thanks Peter!

Pink power and floating pipes, this thing is dope!
