Animation Retargeting is a feature that allows animations to be reused between characters that use the same Skeleton asset but may have vastly different proportions. Through retargeting, you can prevent your animated skeletons from losing their proportions or becoming unnecessarily deformed when using animations from differently shaped characters. With Animation Retargeting it is also possible to share animations between characters that use different Skeleton assets as long as they share a similar Bone Hierarchy and use a shared asset called a Rig to pass animation data from one Skeleton to the other.
