Mixamo addon: Fix for Blender 4.0 and beyond
Todor Nikolov shares a fix for the Mixamo Rig add-on that Adobe is failing to provide themselves.
The “Mixamo Rig” addon is a favourite tool for connecting the wildly popular Mixamo animation & mocap library to Blender.
However, Adobe seems to have abandoned the addon development so it is no longer compatible with Blender 4.0 and later.
Fortunately, Blender addons are open-source which makes community fixes possible.
There are multiple fixes for this addon on the internet but the only one I trust and recommend can be found here.
NOTE: this is fix for Blender 4! If you still use 3.6 or earlier, you should keep using the official addon release found here.
A quick video explaining how this fix came about, installation instructions, and basic usage:

Thank you for this information!
THANK YOU!
Thanks For that.
the original plug-in has moved to a new location:
https://www.adobe.com/products/substance3d/plugins/mixamo-in-blender.html
seems like it doesnt work for 4.3. Am I the only one?
I downloaded this but it doesn’t seem to work for Blender 4.4
Have you tried it?
Yeah this doesn’t work for 4.4. Even tried playing with it in python and nothing
Download the plugin
Extract the ZIP
Go into the folders to ‘mixamo_rig/lib/version.py’
Replace line 7 with ‘_char = bpy.app.version_char’, so that it fetches the new version number properly
Save the file, and ZIP the mixamo_rig folder again. Then just add it in Blender as you would any other plugin.
Quick fix, and works great.
Thank you for this information!
Error:
‘bpy.app’ object has no attribute ‘version_char’
I guess going back to Blender 3 is the only option?
Replace line 7 with
_char = getattr(bpy.app, ‘version_char’, ”)
its works on 4.4.0, i tested
