Adjust retargeted animation using layers

TipConsider the following recommendations when setting up to adjust retargeted animation:

Add the retargeted animation to a layer as you retarget. (Turn on Create New Layer for Retarget Base in the Character Pipe tab as you retarget.)
Create a Control Rig for the target character, and add the rig to a layer as you retarget. (Turn on Create New Layer for Control Objects in the Character Pipe tool.)

These steps assume you have added the retargeted animation to a layer (called Retarget_Base by default) and you have added the target character’s Control Rig to a layer (called <CharacterName>_ControlObjects by default). This layered setup lets you non-destructively adjust your retargeted animation.

To key on top of the retargeted animation

Select a point in time where you want to change the position of the target character, then use the Control Rig effectors to adjust the position of the character.
Ensure that the Reach value of any effector you want to adjust is set to 1. Otherwise, moving or rotating the effector will have no effect. Reach is set to 1 by default for the ankle and wrist effectors.
With the <CharacterName>_ControlObjects animation layer selected, set keyframes where you want the position adjusted.
Repeat steps 1 and 2 until you are satisfied with the adjusted animation on the Control Rig.
Playback your animation.
The target character animation is now modified, and all of its animation is contained on the CharacterName_ControlObjects layer. When you finish making adjustments, you can merge the animation layers together, or bake the animation to the target character.
