I would like to render a realistic head.
I have already set up a convincing skin mat with “standard” VRayMtl,
using diff map + glossy reflection + bump…
Now I’d like to add some SSS but I don’t understand the way to use FastSSS with BlendMtl :
1 - I put a FastSSS in Base mat of a BlendMtl material.
Result : a “wax head” (sss on a 1-color head).
2 - I put my first skin VrayMtl as a coat material
Result is a simple “fade” between the “wax mat” and the “skin mat”
using the blend amount value.
So what is the way to have the FastSSS properties inside my skin mat ?
and not simply mixed ?
