hi, i have a figure which is rigged by using existing skeleton... and there's an ik problem with it. With ik turn off,  the figure's rotation and translation work well. but when turn on, the foot and hands stick at fixed position and doesn't follow the rotation well. In this case, i want it to be ik turn on in order to adjust the figure's hip well, without interrupting the hands and foot transformation. Is this due to the skeleton or a particular figure issue? since the other premade figure does'nt have this problem even with ik turn on.. or am i set and rig my figure wrongly? any solution for it?

 Not really sure what it is you want here. The whole purpose of IK is to "glue" the hands and feet in place, so why does it surprise you that they do not move when IK is on? They shouldn't. If you want to move a hand or a foot while IK is turned on, use the translate dials on the hand/foot. Movie the hip will lead to oddities.  (sometimes desirable, mosttimes not.)

yup, what Trekkie said. IK uses the foot or hand position to control position of the leg and arm. It makes some animations easier.

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

maybe this can help:

after applying bvh to your figure (with all IK off) resave it as bvh or just pz2,
now reload your figure and load NEW bvh (or pz2) and switch IK on.

this may work since poser will save all data with the names taken from your figure (original file could contain some info - for example: IK data - which doesn't work with your figure).
