Ready for another progress update?

I'm pretty close on the general structure of the skin shader. What I need now is to either get some masks to control the lip color or I need to do the lip area entirely with math. (This will not be easy.)

Is somebody willing to make me a lip mask? I need something analogous to a transparency map. I need white where the lips are, black where they are not, and a nice anti-aliased border at the boundary. The boundary should lie just inside the lip geometry. Basically, where lip liner would be drawn, that's where I want a gradient boundary. Then I can drive a shader to produce the lip color and bump effect. (Lip bump is totally different from skin bump.)

If the gradient is right, I can also use the in-between values (between black and white) to know that I'm at the edge and to actually put lip liner there.

I tried to make one with the free Blacksmith 3D Paint, but it only allows 1K maps and that is too course for the detail needed on the lip mask. It needs to be at least 2K - maybe 3K.

Also, it would be cool to have some masks to identify where on the face and body there should be more freckles/oiliness. Basically the upper cheeks and across the nose, as well as a little bit on the forehead and front of chin. Just look at somebody with freckles. Draw white there. Blend smoothly with black everywhere else. On the body, this is top of shoulders, top of forearms, top of thighs.

Also, I think it would be good to have an SSS mask. I'm not sure where that should be, but I know the thin parts of the ears to start with.

I'm trying to think about how to do the eyebrows procedurally.
