I have implemented a new technique for sampling triangles that should provide better results on them.
This is based (copied) in https://pharr.org/matt/blog/2019/02/27/ ... ing-1.html
The improvement should be most visible in scenes dominated by direct light.
Please give it a spin and keep a close eye for any issues

It is activated by default or something special is needed in blendluxcore for that one ?

Re: Low discrepancy triangle light sampling
It replaces the old code, so nothing is needed.
I don't think the difference is that big outside a few specific cases, so you might not be able to promptly see the difference.
