Removing Channel Components for a joint / control – Quick Reference
by David on Oct.06, 2010, under Rigging
To get rid of certain channel components, you can do the following:
Go to Window > General Editors > Channel Control.
By selecting the components on the left and using the right >> arrow to move them to the hidden area, you can get rid of them from the possible keyable components and clean up your animation area. Generally for humanoid rig, you will want to get rid of the visible and scale components.
