In this section you will learn how to prepare character skeletons to work with the plugin.
Rig Component
Add your character to the scene and add the Rig Component to the root bone of the skeleton hierarchy. Usually, this bone is called Root or Hips:
Make sure to click this button.
Refresh Hierarchy will find all the bones in the skeleton and register them.
Note: this component plays an important role, so make sure to apply changes to the character prefab.
Rig Assets
Retarget Pro relies on Rig Assets to store the information about the character skeleton. To create such an asset, right click and go to Create -> KINEMATION -> Rig:
Rig Asset.
Now drag the Rig Component we created in the previous step to the respective Rig Asset, and click the Import Rig button. This action will initialize the asset and build a hierarchy for it.
Tip: make sure to save the Rig Asset after importing the hierarchy!
Element Chains
Now we need to set up Element Chains. Retarget Pro will try to match bone chains, and if it succeeds, it will retarget animation from one chain to another.
Note: make sure to use the same naming convention for all bone chains. If there is a difference in naming, the system might not automatically match the chains.
For a standard humanoid character you will need 9 bones chains:
Pelvis
Right Leg
Left Leg
Spine
Neck
Right Arm
Left Arm
Fingers
Toes
Weapon bone (optional)
Tip: this setup is not mandatory, and it depends on what kind of animations are being retargeted. But most of the time these chains should do fine for a typical humanoid character.

Tip: you can press Shift + LMB to select multiple bones at the same time.
Now, when Rig Assets are prepared for source and target characters, it is time to define retargeting settings.
