Material Combiner Is Messing Up My Avatar

When I use the material combiner, I turns my avatar from the first picture into the second picture. The only problem area is the face. I’ve tried adjusting some of the atlas properties before saving but it always comes about about the same. Any idea how to fix this?

Not only the face, but also the eyes. I’m sure the mouth and teeth as well.

This is because faces of the mesh from two (or more) different materials use the same place on the UV map.

Try to Create Atlas with CATs plugin instead of Material Combiner.
