I just remember the issue. The problem is, that blender is able to have a
UV coordinate at each edge, while CS only allows 3 UV coords for the whole
polygon, so I simply fetched the first 3 ones in blend2cs, the more
correct aproach would be to split the quad into 2 triangles, however that
results in performance loss in CS. So we need a function to detect such
cases and only split if neccesary... I'll see if I can find the time for
this change, but I can't promise anything at the moment.
