UV map doesn’t export from 3ds Max to .fbx to Substance Painter.

Hi, as you can see from my screen shots below I have done a UV unwrap in 3ds Max and I have exported to .fbx and imported that to Substance Painter. Can anyone please advise why my UV map is exporting like this, and not like the one I created? I suspect that this is the default auto unwrap from Max, not my unwrap. I know that the problem originates in Max not in Substance Painter because I have also checked the .fbx by bringing it into Maya where it also has the same problem.

Seems an issue with the Skin modifier. The solution I found was to duplicate the geometry, collapse it to an edit poly, copy the UVW from the other geo and export.

Thanks, I appreciate your investigative work! I ended up redoing the UV map in Maya, but it sounds like I could have used your solution instead.

No worries.
