Does it look like i give a forget
it would be laggy as hell though
It would only be so laggy if you made it way overdetailed. All you have to do is add some advanced animations, moving the wheel joints. Simple. (Or advanced as I just said)
like zosils said, a playertype.1 model for walking, when crouching, changes into another model, similar to the RC sapper.
Don't be a dork. Transformers is dorky, even if there are 2 PG-13 movies, and a 3rd is coming.
