Well my basic problem is once I import a .OBJ file into Zbrush from Maya, I notice I cant see the inside of my 'mouth' model. In fact they appear(faces) invisible from all angles once in Zbrush. I think it has something to do with the normals, but I checked the way the normals were facing in Maya and they were all pointing in the right direction, so Im really confused on this one. Here are some screenshots...

Please let me know whats up!

Hi, that doesn't look normal, excuse the pun.

A few things to try:
(a) Turn on Double in Tools->Display so that backface culling is not performed, this will ensure no polys are hid when facing away
(b) Press Ctrl-Shift and drag a box over an empty area of the canvas to unhide all, or choose this from the masking options.... It's possible that the faces or polygroup was hid by accident.
(c) Open the obj in _another_ application to make sure the faces are there.

Unfortunately that's all I can think of right now!
