After numerous tests with subsurface scattering on human models I'd like to share some stuff.
There are PT shader setups for different body parts included and an eye object with PT shaders and textures to replace the mostly bad eyes of available 3d models.
Instructions for use are in the RAR file.
I'll see, if I can upload the stuff. I already have splitted the RAR file into two parts, since the current total attachment size allowed per post is 5000KB. I get a warning although the first part only has 4096 KB
