Thanks Mario!

I had about figured it out when I came back here to see if anyone had replied.  When I looked closer at the imported mesh I saw it was a group of three different components.  Each component needs to be matted separately. 

Then I read those links and picked up a couple good pointers ie.. put the mats in mat lab for easier loading and rendering and the little "flip" thing in IG.

Thanks, again, and onward to the project.
