The Disney BRDF has a different roughness scale, how does this work with glossiness.userthreshold parameters in PGI and hybrid path? Worst case would be when a user mixes f.i. metal + Disney materials and the respective roughness values don't mean the same. Probably there is no easy solution, someho...

Your scene is working fine here: Are you sure to use the latest binaries ? Umm, downloaded again and reinstalled and now it works :oops: Sorry for messing up. But still there are cases where the sky isn't properly rendered: (right: BiDir, left: original file with hybrid and PGI) Screenshot.jpg cube...

Try again (with the under construction build). While the concrete scene works again, still my glass cubes won't show sky reflections.

It was a general LIGHTCPU, BIDIRCPU and now Hybrid problem. I should have fixed camera motion blur. Thanks for fixing it, tested and found it working! (build 20190626.1) But now the infinite lights are off again: infini.gif and the scene I animated yesterday is a total mess with a horizontal split ...

I also observed that fireflies don't disappear when I disable specular visibility in the lamp properties.

Glossy caustics didn't work for me either in Blender, so I went after it, and it seems, that it dosen't work without the "path.hybridbackforward.glossinessthreshold" parameter. - Didn't work in Blender - I exported the scene from Blender => didn't work in LuxCore UI - I added "path.h...

First try with PathOCL + light tracing + PGI persistent indirect cache + OIDN. 220 samples, 1.5min/frame with Ryzen 2700X + RTX 2070. Motion blur didn't work yet with light tracing, so I doubled the frame rate with DaVinci Resolve. Persistent indirect cache and light tracing fit together perfectly ...

Have started an animation, but when motion blur is activated light tracing does not work

Thanks guys, great progress!
I could not get glossy caustics from Blender, so this feature is yet to be exposed?

unlike BiDir no caustics are rendered in the water. Like BiDir, no caustics are rendered in the water ... are you getting under water caustics out of BiDir ? Under water caustics are the very same definition of SDS paths. I assume you were talking of PGI caustic cache, not BiDir. Nope, BiDir and Pa...
