I'm using someone else's character rig for reference but I'm not sure how I can enable IK solvers for the arms. The hand controller has a NURBS control with an ikBlend attribute, but when I try to use the "Enable IK Solvers" tool, I get an error saying the attribute is locked or connected.
Clicking "Unlock Selected" on the attribute doesn't fix it. Breaking the connections also breaks the ability for it to drive the enabled/disabled state of the IK handle.
The rigged character can be downloaded here if anyone wants to try to help me out: http://www.antcgi.com/2014/06/03/free-model-15-kila-lods-rig-dynamics/
