ok so me and a friend where talking and we where wondering if u could edit the flag to make it look like a ball.... or something to that effect? and if so can you guys explain how it would be done?

Make a msh for a ball and write its name in the geometry line in all the flags odfs.

or just find a ball prop and replace it. but to answer, yes it is possible

kk thanks =D cause me and my friend whatched this funny halo game called grifball and its a lot like football but theres a tiny platform area for the score

Yes, it can be done quite easily. Think of the holocron from Coruscant Jedi Temple Campaign mode.
