Thanks Evo. I understand this. The point is that I need to apply the real textures for teeth, eyebrows, eyelashes, lips (the lips currently are using the base high res face map rather than the makeup map) or (as you said) make the appropriate sections transparent with alternate texture maps. The problem is, with 3DS Max the only ways I have ever done this are through material sub-objects in the mesh itself, or by using a multi/sub-object material. Neither of these options seem to be giving me access to the groups associated with these objects (hence I can't make the eyebrows, for instance, invisible). The eyes themsevles are fine, btw. I just didn't have that material loaded yet in the image above.
