Just summarizing the current state regarding masks and other support for versatile texturing:

I've already made a lip mask and a nipple mask to use in shaders and for photoshopping textures, which I will include in the preview upload (if I don't forget). I can make more masks if the need arises. I know diddly squat about makeup, so I imagine I'm not the best candidate for blush and eye shadow masks, but I can try.

Antonia has builtin brow geometry to make transmapped brows. She doesn't have builtin geometry for pubic hair, but I have a prop that can be used for that. It's just the one layer at the moment, but it should be easy to scale and duplicate that in order to make multi-layer pubic hair.

What I can do is include all these things in the distribution so that texture makers have a common standard to build versatile textures on. What I can't do, obviously, is force all the texture makers to use it. There may be good reasons for distributing "all-included" textures, actually, especially for people selling their products. If you make things too complicated, many people won't use it. That's particularly true in the Poser world, seeing as Poser is the 3d computer graphics application for people who are clueless about 3d computer graphics.
