Just been having my own issues with exporting from Maya using groups. I end up with double everything. So started trying random export settings. and so on..
Anyhoo if you edit your superman.obj so it looks like # Blender3D v249 OBJ File: mkdcu-supermman.blend # www.blender3d.org mtllib superman.mtl g 0 v 0.088371 7.509277 0.234389 It works. All I did was add the "g 0" Still trying to work out what why etc.
