How to Use the Retargeting Tool

Quick Start

Once installed, the Motion Kit Retargeting add-on appears in Blender's sidebar (press N to open). You'll find a new panel called "Motion Kit Retargeting" in the 3D Viewport sidebar.

Retargeting Workflow

  1. Select Source Rig: First, select our rig (the rig with the motion data you want to transfer)
  2. Select Target Rig: Next, select your character (the rig you want to apply the motion to)
  3. Build Bone List: The add-on will attempt to automatically build a bone mapping list. If it doesn't auto-build, you'll need to manually create the bone mapping between source and target rigs.
  4. Apply Retargeting: Once the bone list is ready, apply the retargeting to transfer motion from source to target.

Important: T-Pose Requirement

Your target character must be in T-pose as its Rest pose for retargeting to work properly. If your character isn't in T-pose, the retargeting may produce incorrect results or fail entirely.

To set T-pose as Rest pose: Select all bones in Pose Mode, then go to Pose → Apply → Apply Pose as Rest Pose.

Tips & Best Practices

Character Setup

  • Ensure your target character is in T-pose as Rest pose before retargeting
  • Your character should have proper bone hierarchy
  • Ensure bone names are clearly named for easier mapping

Bone Mapping

  • Try the auto-build bone list feature first
  • If auto-build fails, manually map bones between source and target rigs
  • Map corresponding bones (e.g., source "Spine" to target "Spine01")
