I was wondering how a cube with the Subsurface Scattering would look like, how the colors would blend, etc. It’s interesting to see how little Blue it’s got, being it applied to the Epidermal.
Rendered with mental ray’s Fast_Skin shader. Mapped as follows:
Epidermal :: BLUE :: plane XY
Subdermal :: GREEN :: plane ZX
BackScatter :: RED :: plane YZ
