Which version of the OBJ importer are you using with RDS? (Go to "Help->About Extensions->3D Import->OBJ") If it's not the latest one (I'm using 5.0.3) I don't think you can import models with multiple UV coordinates per vertex. On import, try selecting each option for "Create RDS objects as:" (Vertex Primitives or Simple Meshes. Sorry, I can't remember which you need to use to get multiple UVs per vertex) One of them should fix the problem. Also, as Clint suggests, you might want to use box remap while in UVMapper to make working with the texture map a little easier... HTH, Steve
