inverse kinematic(pin) needs improvement

Anymatter

i believe daz still lack of improvement with inverse kinematics introduced since daz 3.x version. daz ik is good for still or static pose only, its failed in some cases like keyframing animations. 

a simple demonstration is to first pin both foot at 1st frame, then drag the hip vertically downward( half of the figure height for example) at next frame( 10th frames for example). if u inspect across the frames, the foot will not pinned at their actual position, which result in imperfect crouching animation with foot sliding or ballastic limbs movement. i just wish daz will improve the ik so it can maintain the constraint effects towards targeted object throughout the frames.
