Quote - I think ka06059 might be referring to the hands and feet moving when IK is turned on (though that is not obvious from the post, and I might be wrong).

If that is the case, try this. With IK off, zero the figure in the joint editor, then check that the Body and hip translations are zero. Save a pose dot. Turn IK on, parent the hands and feet to the Body actor, apply the pose dot. If it worked the figure should now be in the zero pose, Memorize the figure, if desired turn IK off. Save the figure for future use. The hands and feet should now stay in the same location when IK is turned on.

hi lesbentley , i think u got my point here.... :D. thanks for the reply ! btw i followed your instruction,but still can't  solve it.   i followed your steps in order.after clicking the zero figure button, the hip  and  body is in zero pose, except there's still an x y z offset value for BODY (in joint editor). about parenting, i went to object>change parent , and parent the hands and foot to the BODY. other than that i think i've followed the instruction carefully.....

if u have time pls take a look at this
