How to Retarget Mixamo Animation to Your Maya Rig (and Unreal 5)

Mixamo hands you a free walk cycle in seconds. Then you try to put it on your own character and hit the wall: the animation is baked onto Mixamo's skeleton, and your rig has different joint names, a different hierarchy, and its own control setup. Getting that motion onto your rig means retargeting. Here's how it works, from the manual route to a one-click one.

Why you can't just import it

A Mixamo clip is animation data attached to Mixamo's standard skeleton. Your Maya rig isn't that skeleton. Import the clip and the keys land on joints that don't line up — so nothing moves the way it should. Retargeting is the step that maps Mixamo's joints onto yours.

The manual route: HumanIK

Maya ships with HumanIK, which is free and can retarget between characterized skeletons. The workflow, in short:

• Characterize the Mixamo skeleton (tag its joints in HumanIK).
• Characterize your own rig the same way.
• Set the Mixamo character as the source and your rig as the target, then bake.

It works, but it's fiddly — characterizing both skeletons correctly, matching T-poses, and cleaning up the bake is a real chunk of setup per character.

The one-click route

AnimKit's Mixamo auto-retarget collapses that setup into a single step, and can push the result on toward an Unreal Engine 5 rig — useful if Mixamo is just your source for game-ready motion.

To be clear about the tradeoff: HumanIK is built into Maya and costs nothing, so if you retarget one character occasionally, the manual route is fine. The auto-retarget earns its keep when you pull Mixamo clips onto rigs often and don't want to re-do the HumanIK dance every time.

The Mixamo auto-retarget is one tool inside AnimKit, a Maya animation toolkit. It's paid; the full tool list and the Unreal 5 details are on the AnimKit page.
