But. . . I just tried it again attempting to use multiple groups from another package, through UVMapper with only those two settings and I get the same error. So. . . am I to assume that you can only have one image per object? That doesn't sound right. . . I thought I read a tutorial in the manual that allowed you to create other groups. . . Sheesh. . . I wish the error message gave me more information. I don't even know what I'm doing wrong. :-/
