Thank you, that lip mask is very helpful.

It's arranged a little differently than I had wanted, but it worked out fine with an extra node.

I had envisioned having the gradient start at 0 at the lip edge, and rise to 1 within the lips.

You made it .5 at the edge, rising to 1 inside, and dropping to 0 outside.

That is no problem. I just subtracted .5 from it to get the 0 right at the edge.

Here's a test render. Using the mask, I change to a different shader for the lip area. I'm not yet happy with the procedural pattern for the lip wrinkles yet. But at least I can work now without the distraction caused by the hard edge.

Actually, the extra info about the area just outside the lips (where the mask is between 0 and .5) might come in handy. If I want to do a "got milk" type of effect, for example, or maybe she's been sloppily eating chocolate. Or a drunken hussy who's been doing too much kissing. Hehehe.
