I've learned you absolutely can't trust the import meshing of most 3D apps.

...And a lot of 3D apps don't handle ngons well, if at all - ZBrush (painfully) is another app that doesn't work well with ngons.


As Michael mentioned, you have to let MoI generate the mesh (ngons if your target app supports them), quads & tris, or even just triangles in some cases to be sure that you get exactly what you see in MoI.

Even then, I've found that most of my apps (Lightwave, Softimage) don't properly handle the normal information that MoI provides to make the models look as smooth as they do when they're in the MoI viewport.


IMO, Cinema 4D imports MoI's OBJs the best, and I find Carrara 7 Pro surprisingly does a decent job as well (when I actually use it - haven't tried all cases).
