Sorry for not being precise, I used a flat white background from the world tab in Blender:

I should have fixed the problem.

Can someone redo this (https://blenderartists.org/t/lux-corona-cycles/1143996) Cycles Vs LuxCore comparison with PhotonGI ?

On the CPU too so the we play on a leveled ground (i.e. no Nvidia CUDA Vs slow Nvidia OpenCL).

That scene is very badly optimized.
unclamped rendering, some weird and too strong bump maps, used bcd, there is also some bad performance due to lightgroups...

I was able to get it down to +/- 15 minutes with gtx1060+oidn+cache a while ago but I still think there might be plenty issues with the scene objects..

I'd say rather have Charles convert his 2.1 benchmark scene to cycles and use that for comparison. And even with cuda vs opencl I'd be surprised if cycles was faster. I did several interiors using cycles and it's terrible without ao tricks.

But still to really see some big differences you need complex situation. Maybe benchmark scene but use sun and sky/more complex lighting to show how well luxcore performs+cache+oidn... Just a suggestion.

Will find time to convert it and optimize it for luxcore and photton Gi (It is a very good idea) .

The file is no longer available

I'm basically looking for a "flame bait" LuxCoreRender Vs Cycles and I was thinking to this scene because I was under the impression it was available for download. The scene itself is not particularly important. Just to have a significative banner for alpha0 release

I'm in general also looking for more scenes to add https://github.com/LuxCoreRender/LuxCoreTestScenes

Is it normal, that Blender crashes with Caustic Cache, when there aren't any specular material in the scene?

For example, if I change the dice material in B.Y.O.B.'s scene to mirror, it works fine, but when I change it to glossy (with minimum roughness and high specularity too) it crashes on the start of rendering.

How PGI flickering looks on still (with animated & static seed for sampler)

Ok understood
