The good news - for the most part, Mike and Vicki textures work well on Don and Judy, respectively. I tried a few random textures with MAT files and they worked normally. (I didn't do the microscope routine, so there may be a few touchups needed, but as far as I can tell, the textures seem to map properly. Even tattoos and detailed makeup had no discernable distortions.

The bad news - the eyes are mapped differently. (They have their own, separate maps.) They also have a material called lenscovering. If you prefer to use a different set of eyes, Cake1, Traveler, or As Shahim, this won't affect you.

Poses also work - but Don's proportions are different from Mike's so some poses may need tweaking. (As shown above.) I suspect the same with Judy, but the initial ones I tried didn't have a problem.

These were quick test pictures after trying a few poses and textures at random. Yes, they look a bit creepy!
