When you are manipulating a character with a Control rig, you can pin down the effectors to restrict body movement and influence how other joints behave relative to the pinned effector. This lets you selectively manipulate parts of your character without affecting the entire hierarchy.
For example, if you pin both wrists and ankles in translation and rotation, you can see that no matter how you move the character’s body, the wrist remains in the same position .
Effector pinning A. Character with wrists and ankles pinned in translation and rotation B. The wrists and ankles remain in place even when the Hips are translated along the Z-axis.
When you create a biped Control rig, IK effectors on the character’s feet are pinned in translation and rotation by default. On a quadruped Control rig, the feet are pinned in both translation and rotation.
The Character Controls window toolbar contains options that let you pin and unpin effectors.
The following table describes keyboard shortcuts for pinning and unpinning effectors:
