I was trying to make an IK-FK switch, and I’ve found a problem. I have an FK chain, an IK chain and a deform chain. The bones in the deform chain are constrained to the bones in the FK and IK chains.
If I use another object to drive the IPO curves for the influence, the switch runs OK. But if instead of the object driver I use another bone of the same armature, nothing happens.
Any idea about what I can be doing wrong?
You can see a simplified blend with the problem in (http://www.pairal.net/notWorking.blend). Just three bones (bone 3 has copy rotation to bones 1 and 2) and the controller bone (x). If instead of x I use the cube, it works OK.
Thanks in advance for your help!
