It has already been done.

Where can I find it? I only see Scene::GetLightCount().

I can get consistent brightness out of this when changing path.hybridbackforward.partition from 0 to 0.8! I thought this setting only affects PathCPU not PathOCL. But the crazy brightness volatility in PathOCL appears only when light tracing is set to 100%. So you change to CPU, set partition, then...

Sorry for my ignorance..but "variance clamping" is it available in LuxCore... I'm quite sure I'm near a facepalm It's just called "clamping" in BlendLuxCore, it's in the render settings below engine, sampler etc. Using the last build ( & the last Blend addon), about the mess...

I have exposed the setting.

You can do this by setting the "DLS" mode from "auto" to "disabled":

I can get pretty bad performance in cycles's reflections too if I leave defaults of min. bounces to 0 and leave cycles to automatically decide when to terminate ray. But! If I set min. bounces to the same value as max bounces in cycles, I get just a small performance hit but a lot cleaner glass and...

Glad to hear that, nice results.

The only crashes I seem to be having with PGI is when trying to re-work an old scene (which is probably already a mess due to my learning curve), and then swapping an old MATTE node with the new Disney appears to fix it. Sounds weird, can you post the scene (possibly simplified while still reproduc...

I have updated the defaults to be the same as in LuxCore.
I started to look into the screenwindow -> subregion issue, but I'm not done with it yet.

How to? Enabling "add light tracing" I've tried to create caustic using caustic caching but it crashes everytime...it seems that it eats a lot of RAM Yes, "add light tracing", but don't enable the caustic photon cache. With point light in the inner part of the light fixture or a...
