Why does this happen? Skin clipping red glow... Tweet

[Tigersan]

Every time skin clips into itself theres this red glow... I'm guessing its because of subsurface scattering, and displacement map... But it didnt happen on other renderers... wth? I cant pose my models in any artistic way with any artistic contrasty lights setup, without getting this effect... :/

Hmmm this is clearly an error, renderer shouldnt work like this it should ignore clipping... I was hoping for some response, but don't trample over each other to respond...

I am now sure what you mean by "skin clips into itself". If you have geometry you have inside the figure's body is going to effect subsurface scattering. That's the way it works. I think you need to morph the internal geometry away from the skin. In theory the SSS light should bounce around inside the figure regardless of the material on the surrounding polygons. So the interface between material zones on figures should cause SSS problems - as long as the vertices are welded.
