Ok. Im making a vehicle thats going to use two wheels. But, these two wheels will be not circles, but ovalish tracks. (a tank). So, i want the tracks to rotate obviously, like wheels do, but first of all how can i change the wheel mount point location and second of all how can i make it so the track doesnt just flip in a 360 rotation? Can anyone help me out here? I want the tracks to move smoothly over the hubcaps. Plz help me out.
