Just for the record: "Weld vertices along edges" alwas messes it up for me. If i leave that off, and just go for Quads and Triangles, the result is good most of the time.

Hi jna, thanks for mentioning that, that can help some others in the future.
When that welding option is checked, the OBJ file that is created will be more complex in a certain sense because it will have faces that share a single 3d vertex, but have unique entries for uv and vertex normal for each face.
Some programs don't allow faces to carry independent information on them like this. So when they see "per-face" information they have to do something to try and reorganize it.
Welding turned off basically avoids this situation - adjacent faces will either share all information in common (3d pt, uv coordinate, and normal), or none instead of partial sharing.

FYI: Changing the File>Export>Obj>Meshing Options>"Divide larger than: [#]" pull-down to 'All', fixed ALL my problems. :-)

I tried that just now, and that seems to be a winner!
Another, I guess more expensive way to deal with the import situation, is running Npower-RhinoToMax.
An import plugin, that lets you open 3dm files from within 3dsMax. A nice feature is that it lets you quickly 'chamfer all edges'.
Could save you some time.

you have an export file format 3ds direct from Moi ;)
From: jna
It was immediately after trying that, my search for an alternative began..
From: Michael Gibson
.3ds is a very old and limited format.
It is not able to contain vertex normal smoothing information, can only have triangles in it, and is limited to 65535 vertices or faces in a single mesh piece.
It's generally something you should use only as a last resort if there is no other choice.
