Check
it to make sure it works, but make sure
you Undo so that it goes back to the
right spot. After creating the IK chain,
you can create your Wrist controller;
I renamed mine CTRL_Wrist_R.
To Create the controller a circle, then
rotate it 90 degrees to the right while
holding shift, and then select the original
and rotate that one 90 degrees again
while holding shift to have 3 circles.
Then convert a circle to an Editable
Spline, and then click on vertex sub-object
mode, and then Attach Mult. and click
the other 2 circles so you have one
circle all together. Next, once you
have your controller, you will align
its position only to the IK chain, and
then you will align its orientation
to the Hand_Dummy_R object. Then, select
the IK chain and link it to the CTRL_Wrist_R.
Then, select the Hand_Dummy_R object
and go to Animation -> Constraints
-> Orientation Constraint and once
the rubberband shows up click on the
CTRL_Wrist_R. So pretty much, this is
what you should have, and NOW, all you
have left is to setup the Double Rotation.
