Certain actions were not applying to certain characters such as "BigVegs" which has bone names like "newVegas:Hips", and apparently certain armature tools won't work until you rename the bones as well. In short, mixamo names it's bones like "mixamorig:Hips" and "mixamorig:RightUpLeg", and blender's naming format is "Hips" and "UpLeg.R" etc. It just so happens that I had a previous problem with the bone naming conventions supplied by mixamo inside blender. I had the same problem as you: weird error messages and a badly mangled armature after running the "Mixamo Rig" add-on. File "/Users/20262059/Library/Application Support/Blender/2.93/scripts/addons/Mixamo add-on for Blender/mixamo_rig.py", line 176, in execute it still had an error code this time with this error message. I then tried again with a character from mixamo, this time with an animation. This is a character rigged on mixamo and then downloaded in default pose Python: Traceback (most recent call last):įile "/Users/20262059/Library/Application Support/Blender/2.93/scripts/addons/Mixamo add-on for Blender/mixamo_rig.py", line 176, in executeįile "/Users/20262059/Library/Application Support/Blender/2.93/scripts/addons/Mixamo add-on for Blender/mixamo_rig.py", line 1902, in _make_rigįile "/Users/20262059/Library/Application Support/Blender/2.93/scripts/addons/Mixamo add-on for Blender/mixamo_rig.py", line 1122, in add_legĬns = c_foot_ik_pb.constraints.get(cns_name)ĪttributeError: 'NoneType' object has no attribute 'constraints'

When I try to use the mixamo addon with my character it gives me this error message.
