Hi

I am trying to make a simple IK chain (4 bones) Shoulder, arm, forarm,hand

-A master bone and childs bones.
I do my Ik setup (goal, IK rotation), but when I move the null (goal), all the bones move away from each other (they are not linked like a chain).

Do I miss something, an option to turn on ?

Thanks

All items need to be parented to each other in a heirarchy.

The Ik was not setup on rotation but on position.

RebelHill, finally I have got the time to watch your videos. Excellent work ! I am impressed.

Is there a script or a way to access to the Twist and Record rotation fonction in layout. Kind of a shortcut to rotate HPB by 90 deg, until you get the expected orientation.

To not twist by "hand".

Thanks

not really... because thered be no way for the script to know which way round it was that you intended or wanted the bone/item to be oriented. So you always need to tell LW which way something is meant to orient, either via the skelgons in modeller, or twist bone in layout... then rpr does the job of matching that for you.
