Hey those are nice renders
I updated 1st post with a new version of SkinSSS2 and added the SimpleSSS2 compound
Kzin, diffuse having control over SSS was actually done by mistake. Although it obviously works out really fine, I repaired that in the new version because it's somewhat unexpected and some tuning control is lost. It's possible however to get the exact previous behavior by connecting the diffuse texture to both "Diffuse" and "Diffuse+SSS Multiplier" together - this is at least how it was wired by accident in the first version.
Old version still available here
Some other changes in the new version:
* Rendertree connectors/layout fixed, exposed "scale" for texturing and added Sampling Radius Mulitplier
* Tidied PPGs a little
* SkinSSS2 Compound has default values from Kzin's post above
