ok I'm using maya 2008 and I'm new to it obviously. I need help with something simple from you maya experts. I already have a model. I pull the object into maya and I get this error first:

"Your OBJ file contains faces shared by multiple groups. Maya cannot creat multiple objects for this file. A single mesh object will be created instead. The OBJ group information will be captured in Maya sets."

Not sure what that means. So then once the model is up I scale it up and then I add smoothshade to all. Next I open the uv editor and all the uvs are stacked on each other. I need help on how to move them to separate shells.

any help would be appreciated. I've attached the object file.
