Thanks
I export from Moi using LWO which is basically the same as a native Modo LXO format. The mesh normals are all good the only thing I do it unpack the UVs as they are basically packed over each other. The projections aren't the best as they aren't proportional but this is easy fix.
If I use OBJ I don't have as good a result when I use N-GOns so I use LWO.
I would suggest you try using triangulation and not just n-gons or FBX it may work better for you in Max.
I don't use Max often so can't really say.
Mark.
