Why do we need to rotate the texture ? In TRViewer I only associate to each vertex of a face (tri / quad) the texture coordinates from the tr2_object_texture_vert structure (I juste add the X or Y -pixel field with the matching X or Y -Coordinate field to have the (u,v) coordinates), and I never saw problems in texturing...
