Quote - The Phong node generates its strongest output when you're on a point of the surface that is pointing to a light. So one of the ways to fake SSS is to use a Phong node to control it. Front-side SSS is strongest when the surface is NOT pointing at a light. So I can get this behavior if I make the amount of SSS (redness) inversely proportional to how much output I'm getting from a Phong node.

this is different then VSS skin shader right?

the old cheat witt specular connected to a blender node?
