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...

a simple fluorescent bbrrdf
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
