I've been trying to help out another Member, DarkePhazeGraphiX, in her thread:

Can someone give me a brief tut on "FauX Skin Texturing"????

And thought I'd just update this thread, of my own, with some of the images; as this is where I link people, when they ask about SSS.

Here is an image, of Mari e17's Jullisa texture, before and after Face_Off's HyperRealV3.  These are the HyperReal settings Im getting comfortable with, so this transformation took all of the 20 seconds the script ran for!

Here is where I am with Fair skin.  I often say that medium Complexions work much better with SSS, and REALism, and this is why.

 The top left is as best as I've done; without SSS, or Realism.

The top right is as best as best as I've made it with HyperRealV3.py.  It is'nt bad, but I think it is too busy, and prefer the much smoother shader of the first image.

But mind you I've had weeks of practice with Face-Offs script.  The bottom picture is an example of what happened the 99, of the hundred, times I've tried to get his script to work; with this free texture, from Valea, named Natasha.
