Exporting as an OBJ with UVs

FOUND HERE

"- Do you have UV’s and/or shells outside the 0->1 range?

That might be the problem."

"- The standard UV-range (0 to 1 U and V) is the first quadrant - the stuff north east of the origin. On the picture it looks like everything is within those boundaries."

OBJ exports into Substance (with UVs) will not work if there are things in the export that do not have UVs

   - Will crash
