so at each rendered frame I have to correct foot IK effector to maintain distance between foot and ground from oryginal animation? 
Witch solution will give better look motion:
- each render frame correction
- correction counted at start of next step and applied with a weight on oryginal animation (start if next step CorrectionWeight=0...with interpolation to end of step CorrectionWeight=1.0) ?
