I want to make this model into the game http://images-cdn.moviepilot.com/images ... 737213.jpg

i dont know how i would do this
i was thinking maybe put palpatines cape on the gungan model but i dont know how to do that

that's not a texture problem. I'd take the head and put it on palpatines body.

All you need can be found under 3D Modeling>FAQ.

ok i went to 3d modeling faq and theres a lot of stuff there where would i need to go to find out how to do that

Not sure which faq thread that would be under either, but I did something like this last year and needed help. Here is that thread: http://www.gametoast.com/viewtopic.php? ... 82#p516782.

The most relevant part is Ace's post about using polygon select to get what you want (in your case, the gungan head) and extracting it to a new object. Then I guess you'd just delete palpatine's head (also using polygon select), and import the gungan one.
