Spanki, you have to add them to the obj file, or provide a new uvs file to impliment them. I wasn't considering you knocking anything at all, but was curious as to your opinion. If you read up, there are only 2 small edits to make a cr2 reference an original obj file, but creating addition mat zone requires a LOT more work on the developer part.

Way too many people take way too many things way too seriously.
