Multi layered SSS skin model

[CTZn]

The transparency from the SSS is visible at some aera very strange did you watch? like on the arm but not on the ear, on the eyes but not on the lips? Did you know what it can be from?

I think that it is a magnifier effect, where light focused within the body is hitting the other side. If that is true that tells us a few things maybe:

• - there is no opaque sub-body (there should be one, because the sss zone is very thin in real life)
  - the scattering coefficient is not strong enough (focusing should not happen this clearly)
  - absorbtion is too weak
  - if not uniform, the phase function is too directional

Maybe all these points are not true, but that may give you a few directions for research.
