Hmm, that's kind of unusual - normally it tends to be the other way around, with n-gons (especially concave ones with a lot of points in them) can tend to cause difficulty in some other programs.

It may be a bug in MoI's triangulation, or it may indicate that there is something kind of messed up with the surfaces in that area, like possibly a small loop in a trim curve, or something like that.

If you can send me the model file that has the piece of geometry that is giving the black facet problem (if you can just delete other parts that are not related to the problem), that could help me to track down the problem.

Thanks,

- Michael
