Some object file I import into Poser have multiple texture regions and others don't, even when the obj itself has separate meshes in UVMapper and if I open it in Rhino. Now that I am trying to learn myself how to use Rhino and UVMapper for Poser I can't seem to figure out how to assign the texture regions so they appear in Poser's material editor. Even I 'paint-brush' recently downloaded that came with multiple textures opens up with only 1 texture region in Poser? Can some one please point out what I am failing to see? Thanks all.

You need to familiarize yourself with the wavefront OBJ format. The OBJ format used by poser is basically ascii text format. The groups and materials are defined together like this: g head usemtl skin "usemtl skin" is the material for the group "head". Open a poser figure's base OBJ file in a text editor and have a look around. -Jeff
