Idiot Collision Detection

Ok, so I read the manual and I ripped apart all of the tutorials and I still have no idea what to do. I have a cup that I made in Milkshape 3D. Does it already have the collision normals?? How do I create them. Im trying to get an object into the cup. Any help is greatly appreciated.

I don’t think we can help more then quoting the manuals at this point. Most eggs don’t have collision exported when they are created so you have to monkey with them.
