You need to select the polymeshes for the ear parts and "name polymesh" from the pull-down window for polymesh. Then when you bring it into UVMapper you can select the named parts, I.E. left ear, right ear etc., and move them away from the rest of the mesh. Additionaly, you can resize them or change their mapping modes and rotation angles independant to the balance of the mesh. There is a new version of UVMapper out for both MAC & PC.
