ok, so far, i havent worked with much in maya except basic shapes and lofting (a little bit), anyways, if someone could just answer these questions, i'd be greatful:
1. whats the best way to rotate tires in an have them rotate at the right speed so they dont look like they are sliding or moving too fast?

2. how do i make objects be affected by gravity fields

3. how can i make tire tracks in the terrain?
