Per request, these were the surface mats for Skin and Skin2 on the fourth figure in post #17.

For the third figure the settings for Skin2 are the same and the top skin layer was made invisible with all the colors for "Skin" at zero luminance. This means, without using Staale's second skin layer, it was essentially a standard Posette .

And a correction, there are only two skin layers, not three.
I misunderstood staale's readme. It's the UV template itself that has three layers. Two for the skin and a third for the eyes.
