I guess what I'm asking then is, is it *true* kinematics, i.e.- do the objects really know that they are colliding, and would a kinematic chain be visible in the keyframer that you could interactivly manipulate. In other words, would the only type of object manipulation possible be through an IPAS requester box, or would you do right in the keyframer? The only thing I don't like about IPAS is that I feel that in some instances it's not interactive enough with the rest of the interface. BTW, what is SDK?
