>> rolling around the rim with no slippage. I'd use a dummy in the center of the rim to control position along the rim, and roll the ball itself for the rolling movement. It would help you greatly if you calculate the circumference of the ball and rim. Determine how much linear distance the ball covers along the rim per frame. Compare this to the circumference of the ball to get the angle per frame of ball rotation. Then insert keys as necessary to obtain this movement. – Dave
