About Import Mixamo – Root Motion

Import Mixamo – Root Motion is a Blender add-on for batch importing FBX animation files downloaded from Mixamo and applying root motion. Users can select multiple FBX files via File > Import > Mixamo Fbx and adjust options in a side panel before import. The add-on removes the “mixamorig:” prefix, renames animations by file name, applies transformations, fixes animation strength, and deletes redundant skeletons matching the “Armature.00*” pattern. It creates a root bone that records root motion and bakes the character’s displacement onto it, offering multiple calculation methods. Additional features include optional replacement of “Left/Right” with “.L/.R” suffixes and a panel for custom bone names. Version 1.0.4 adds a Rotation option that adds a Copy Rotation constraint so the root bone copies the hips bone’s Z‑axis rotation in world space while disabling the hips bone’s inherit rotation. The add-on is compatible with Blender 4.2 LTS and is released under the GNU GPL v3.0 or later.
