Has anyone managed to change the main menu orb to have its own material. It seems to be shared with the mesh directly behind it (menucell is the mat name).

I Want my orb to be its own color, or rather, have its own transparency. How would I go about giving it its own skin.xbx value? I don't understand where, in which xap, the material names are loaded and colors defined.

hopefully this helps.
I wrote most of it as a reply to this thread and decided to make it a better tutorial. If you're not sure on anything you can ask in here or there.
