Hi. I made the attached MatCap from a photo (of someone’s rearend, so I can’t post the source pic). The matcap has actual shading from skin. I really think it looks good, but I haven’t tried polypainting over it yet. If you do add color, such as lips, makeup, whatever, you can adjust the intensity slider in the material modifiers and it should adjust to your painting.
Hope you enjoy! I will experiment with it some more and see if I can’t come up with a few more versions, such as wet, feminine, child, etc. Let me know if there is an interest and I will work on it.
Just in case you are wondering, I chose the rump picture because it was a closeup and was fairly round (very gifted person), which is easier for matcaps (such as a globe or ball shape) and the colors were clear and unshadowed.
The top row of heads were done by other artists, but the bottom row are my own work.
