# Retargeting

General

• Motion clip something maybe.
• FBX Character Import (Combination of FBX Skin Imporot + FBX Animation Import)
  • In the olden days, it would be Scene Character Import if you are using Houdini’s native object level rigging toolset, which was already superseded by Kinefx Rigging Toolset (i.e. SOP level rigging)
• FBX Animation Import
• Rig Match Pose Node (Hit Enter to enter to its interactive state)
• Do not translate or scale the skeleton joints you see in the Rig Match Pose state.
• Map Points SOP (Hit Enter again to see the node state )
  • Physical Full Body IK solver, then that solver prefers a sparse mapping.
  • FABRIK solver, then that solver prefers a dense mapping.
• Fully Body IK SOP
• FK Transfer. Might be better compared to Full Boody IK SOP when there is a need of direct translation of joints. Like fingers. There is no need for IK solver for that one.

Mocap Configuration Mapping

Retargeting Scenarios

Retarget With Same Skeleton

This would be the best case scenario where your skeleton matches your mocap such as using mixamo characters with the mixamo animation.

Retarget With Different Skeleton

For the most part, you will have to deal with different skeleton and animation skeleton.

Retarget With Different Skeleton

To get a stable Full Body IK Behavior, keep the mapping to the bare minimum such as the wrist, shoulder, hips, ankle etc. For the fingers, it would be best just to use a simple FK transfer of the source and target skeleton.

Note that there is two mapping attributes. One for the Full Body IK and the other is for FK Transfers
