Hi Shaun - stuff like that is usually due to the vertex normals not coming through and instead having them get cooked up by just averaging the polygon face normals.

For going into Max, I recommend using FBX format which seems to be where they focus most of their development attention on, the Max OBJ importer seems to have had some various issues for quite a while now.

Make sure you also install the latest FBX import plug-in for Max as well, you can download it somewhere from Autodesk.

Probably if you use FBX format instead of OBJ you'll get the vertex normals come through and since those vertex normals come from the original NURBS surface you'll usually get a much smoother and steadier shading and reflection from them.

Most other rendering programs handle OBJ imports fine, but it seems to have been a long standing problem area with Max, which is why I implemented the FBX importer out of MoI.
