Quote - Les, what version of UVMapper did you use?

I used UV Mapper Classic to make the original obj and create the material zones, but since then the obj was exported from PP2012, which accounts for the comments in the middle. Any way I doubt it has to do with UV Mapper, unless Paloth and markschum also used UV Mapper. Paloth made a cube in Modo, and markschum in LW, both those cubes manifest the same type of bug, but neither mention using UV Mapper.
