I'm sure (as in really hoping) there's a simple explanation to this issue, but I just can't seem to make it happen. I've made a model in Max, set up the UVs in Max and applied textures. I import into XSI to work out the tangent map, and then reapply the texture maps. Textures look great in the XSI viewport. The problem is when I export the mesh, convert it, and get it in-game, part of the UVs have gone awry.
The funny thing is, it's not all of them. It's just 3 or 4 UV groups out of around 30. I tried importing the mesh back into Max to see what was going on. My UV groups that were previously a sillouhette of the core of my structure now look like they belong in some kind of surfing brochure heading the huge waves paragraph.
