Is it possible to implement "Automatic Parameter Control for Metropolis Light Transport"?

Here i post some nice feature in fstorm that could give really good inspiration ! https://fstormrender.ru/fstorm-1-2-5/

.really like the scratch procedural texture

.and texture compression feature

Nice stuff, but also geopattern and light include/exclude features are great. And geometry elements and dirt texture too :D

just a sample of what the geopattern could be used for.
It kinda reminds me of tissue addon for blender but much more optimized and generated at rendertime...

The same "trick" used in LuxCore for rendering glass dispersion could probably be used here too :idea:

Another engine getting multiple scattering GGX is IFX Clarisse v4
"... it doesn't affect render time..." :o

I'm fairly certain this is using the multiple scattering ggx paper that we will be implementing at some point in the very near future. I do think the comment he made about it being free it's a little bit of a "stretch" tho, as they are using one or more interior bounces to achieve multiple scattering, so it does add a little time to bsdf calculations
