Very interesting work. Regarding te intermediate result, note that if you have a strongly directional light, the modelled version will have a really hard time while the layered version will easily compute it.
It might be interesting to render the modeled version with sppm as it should overcome the difficulty.

Well, here it is (matte, glossy, layered, modeled) with SPPM: it didn't really like the modeled version:

After more testing I can confirm that the layered mat is too dark. I suspect it is due to my sampleF() function so will re-write that bit and post a fix when it's complete.

I coded the layered material support for 3ds max.
Here is a test with an aluminum base, carpaint on top of that and rust on top of the carpaint :lol:

There is an issue with my current sampling method that results in some layers being too dark - I've just pushed a fix to partially correct that. When I can figure out the actual problem/ fix it i'll let you know.
