Flexible retargeting

Animate with your rigs and your characters.

Upload any bipedal rig with whatever bone hierarchy, naming convention, or joint count your pipeline uses and our IK retargeting maps motion to it instantly. No manual bone mapping. No retarget asset files. No cleanup passes. Just your characters, moving.

Upload. Apply. Done.

1. Bring your characters

Upload the rigged characters your team already uses. Custom skeletons, studio rigs, proprietary bone hierarchies — as long as bones are named, Uthana can retarget.

2. Retargeting automatically

Uthana's learned joint mapping algorithm analyzes your character's skeleton and maps motion to it without you needing to do anything.

‍

3. Export and use your rig

Download as FBX or GLB and bring it back into your pipeline on your original rig. Apply retargeting on as many characters as you upload.

Adapts to any proportions

Uthana's retargeting solves for where joints should end up, not just what angle they should be at. The result is motion that respects the anatomy of the target character, maintaining foot contact, natural reach, and believable poses regardless of body shape.

‍

  • Solves joint positions, not just rotation copies
  • Maintains foot contact and ground plane alignment
  • Preserves motion intent across different body shapes

Fits your pipeline

The full retargeting workflow is available through Uthana's GraphQL API — retarget programmatically across your character roster without touching the browser. Generate motion and apply it to your character within your existing workflow.

‍

  • Plugins available for direct integration
  • FBX and GLB export with full editable keyframes
  • Available via GraphQL API for automated pipelines

Works with any bipedal skeleton

Traditional retargeting breaks when skeleton structures don't match — different bone counts, different hierarchies, different joint naming. Uthana's IK retargeting doesn't need skeletons to match. It uses a learned joint mapping algorithm that figures out how to apply motion to your specific rig automatically.

‍

  • Handles different bone counts and hierarchies
  • Works with Mixamo, Unreal mannequins, and custom rigs
  • No IK chain setup, no bone-by-bone mapping
FAQ
Frequently asked questions about Uthana flexible retargeting
▶

What skeleton formats and rigs are supported?

Any bipedal skeleton — your studio's custom rigs, Mixamo exports, Unreal mannequins, Unity humanoids, characters from Maya or Blender, marketplace assets. If your pipeline produces it, Uthana can retarget to it.

▶

What if I update a rig partway through production?

Re-upload the updated character and the retargeting re-maps automatically. There are no retarget asset files to maintain or update when your rig changes.

▶

Can I retarget motions from any source?

Yes. Text-to-motion, video-to-motion, library clips, stitched sequences, looped motions, and real-time recordings all retarget identically. The source doesn't matter.

▶

Can I record my session and export it?

Yes. Hit record before you start, perform your motion, then stop recording. The result is saved as a motion file with full editable keyframes. You can preview, trim, and download as FBX or GLB.

▶

What if my character doesn't have a rig yet?

Use Uthana's auto-rigging to add a skeleton in under 30 seconds, then add motions to it immediately.

▶

Does retargeting handle fingers?

Yes! If your rig and the model used to generate the motion both support finger data, that motion gets mapped. Currently, all video-to-motion models support fingers, as well as some text-to-motion models.

▶

Is retargeting available through the API?

Yes. Retarget motions to characters programmatically via the GraphQL API. This is useful for batch-processing a moveset across a large character roster, or for building retargeting into your studio's internal tools.
