Looks more like the anterior super structure has exceed the load bearing capacity of the container material resulting in shearing and eminent containment failure. :lol:

 

Seriously though you should consider picking up Blender even if you only use the UV mapping capabilities to start.

If you do that then there's a couple or three of us around that can walk you through the process and get you squared away pretty quick.

I would recommend using the stable 2.49b version over the 2.5x series at the moment since you never can tell if the OBJ importer/exporter will work on any given revision.

If you do get Blender 2.56 download the revision from the Blender site since the OBJ importer does work correctly in that version.

Get the zipped version either way as it will run from any location on your computer.
