Mixamo Animation Retargeting – Game Development

Note : This product is not made by, or affiliated with, Mixamo or Adobe Systems in any way.

In addition to the base setups required by the Retarget Manager, the plugin implements some advanced functionalities to obtain a perfect retargeting and optimal integration into Unreal Engine 4:

• the Retarget Base Pose is computed analytically, to obtain an exact and perfect match of the skeletal meshes used during animation retargeting;
• a Root bone is added to the Mixamo skeleton (and all related skeletal meshes), allowing the use of Root Motion for animations.
• a Root Motion animation can be computed from a pair of normal and in-place Mixamo animations .

To run the too l:

• ensure that the Unreal Engine 4 mannequin skeleton in your project has the “Humanoid” rig set;
• select a Mixamo skeleton asset and execute the “Retarget Mixamo Skeleton Asset” contextual action.

The tool also supports batch processing.

Technical Details

• Editor plugin.
• No third party code.
• Automatic setup of Translation Retargeting options.
• Automatic setup of Rig mapping.
• Analytical computation of the exact Retarget Base Pose. Some bones preserve the original component space orientation due differences between Mixamo and Epic reference poses: “Head”, “LeftToeBase”, “RightToeBase”.
• Addition of the Root bone to enable Root Motion animations.
• End results can be hand-tuned if needed
• Animation Retargeting is done with the standard editor pipeline (Retarget Anim Assets > Duplicate Anim Assets and Retarget).
• Conversion of Mixamo animations to UE4 root motion animations (both “normal” animation and “in-place” animation are needed for the computation.
