AnimExport Pro — game animation out of Blender, in the shape the engine expects

Root motion on the object instead of the hip bone. One FBX per clip. Mixamo rigs cleaned up. A humanoid check that fails in Blender instead of in the engine.

Getting an animation out of Blender is easy. Getting it out in the shape Unity or Unreal wants is the part that eats the afternoon: the travel has to sit on the object, each clip has to be its own file, the bone names have to match the humanoid set, and the rig has to pass a validation you cannot run until you are already in the engine.

AnimExport Pro does those four things from the sidebar, and the batch export around them.

Root motion, both ways

• Lift the travel off the hip bone and onto the object, per axis — horizontal for walks and runs, vertical when a jump needs it.
• Put it back when a clip has to return to being in-place.
• The original action is kept; the extracted motion lands in its own action.

Clip splitting

• Mark frame ranges in a list, press once, and every range becomes its own action rebased to frame 0.
• Batch export writes one FBX per clip, named after the clip.

Mixamo cleanup

• Strips the mixamorig: prefix and maps bones onto the standard humanoid names.
• Fixes the scale and removes the extra root — each step optional.
• Retarget to Rig constrains a Mixamo take onto your own skeleton.

Humanoid validation

• Checks all 20 bones an engine humanoid rig requires and names the ones that are missing or misnamed.
• Twist bones are recognised, not reported as strays.
• You find out in Blender, where fixing it costs a minute.

Blend preview

• Cross-fade two actions in the NLA to judge a transition in the viewport, then clear it — nothing is left behind in the stack.

Compatibility

• Blender 3.0 and later, including 4.x and 5.x.
• Unity and Unreal Engine export conventions.
• Entirely local. No account, no network, no telemetry.

v1.0.1 — Root motion, clip splitting and Mixamo cleanup work again on Blender 4.4 and newer. Blender 4.4 moved F-Curves out of the action into slots and channelbags and 5.x removed the old path entirely, which stopped those three functions dead; curve access now works on both layouts. Verified on a rigged, animated character.
