Another thing, what is the different between InverseKin CHOP and IKSolver. The performance is the same? When is better to use one or the other?The IKSolver is meant to work with mocap markers where each bone can reach for an arbitrary number of markers. So it's not really comparable. For traditional character rigs, use the InverseKin CHOP.
And finally using InverseKin it doesnt explicitelly overrides nothing in the bones parameters, so I guess it is puting the rotation transforms in the bone's pretransform????The bone object has a "Kinematic Solver" parameter that indicates the path to the InverseKin CHOP to use for its rotations when computing its local transform. By doing so, this frees the Bone's regular rotation parameter for FK keyframe animation. Regards, -Edward
