I need to convert in frames a spin behavior, because i need a soft transition from a movement to another. Mark, i've tried to modify the behavior over time but i can't reach the desired thing. Shonner, your idea can be good, but maybe you can have the same effect using a discrete tweener. Nicholas, i need to rotate a kind of wheel on his axis while it rotate in other directions. Mmmm, i love the challenges, but this simply thing seems impossible for now with carrara. Thanks -TOXE
