At first, i used a huge poly count model (To be sure it looked smooth) A subsequent test, with a default obj export (very low poly's) looked the same...
Hi Felix - yeah you probably want to export an OBJ file out from MoI for going into Simlab and also it probably doesn't deal with complex n-gons very well so when doing the export set the option for "Output: Quads & Triangles" instead of "Output: N-gons" and that will probably avoid some problems.
