Hi.
As you see the photo below, when AlSurfaceMtl has certain SSS mix amount,(0.3, for example) it has blotches around mouth and nose.
It depends on combination of HDR lighting and SSS mix amount, I think.
It occurs in some HDR with specific SSS amount, and not in different setting. Seems randomly happens.
Moreover, I tested a lot and, now this material doesn't have any texture except for Diffuse.
My Vray version is 3.50, 3dsMax 2017 SP3.
