P8 doesn't have either. We're talking about effects implemented in the shader.

Open the PR3 control prop in the material room and look at the Template Skin shader. On the left are all the important parameter nodes. Among them you will find PM:Gamma (for GC control) and PM:SSS (for SSS effect control).

The SSS (subsurface scattering) is not the real thing. It is based on a loose rule that areas in partial to deep shadow tend to be more red than parts that are lit well. I was told years ago it was SSS - according to face_off. I no longer believe that - I believe it is more to do with light bouncing between close opposed skin surfaces multiple times, becoming more pink with each bounce, such as between legs and in armpits. If you enable IDL, even without my skin shader, you'll see these areas become more red. So I suggest reducing the (misnamed) SSS effect in the VSS skin shader with IDL.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
