Hi tony, so according to the Artlantis page here:
http://www.artlantis.com/index.php?page=products/studio/connectivity

it seems to support importing OBJ format, so that's what I would recommend using instead of 3DS.

You may want to try these settings when exporting from MoI:
Output = Quads & Triangles
Weld vertices along edges = off

That may give a better chance at getting the vertex normals transferred into Artlantis, it makes for a better quality shading if that information goes through.
