I have an idea that would make Transformers possible, but probably very buggy.
The vehicle in car mode would have to be used with... I don't know, a command.
When the command was used, the car would do an animation of transforming.
It would hide the wheels and (maybe) delete the tire smoke.
Animations for running, and different transforming animations for different scenarios, like driving forwards, backwards, and being in mid air.
Is this possible or is this completely out of the question?
