Mixamo Rig addon in Blender 4: a Community Fix!

Table of Contents


The Mixamo Rig addon for Blender has long been a valuable tool for animators and character artists. However, with the release of Blender 4, the official Mixamo addon has become incompatible, leaving many users frustrated.

But fear not, the community has stepped up to the challenge, and a reliable fix is now available!

Developed by the talented Blender enthusiast Xin, this community-driven solution ensures that you can seamlessly integrate Mixamo’s vast library of animations into your Blender 4 projects. In this blog, we’ll explore how to download, install, and use the addon.

Downloading and Installing the Mixamo Addon for Blender 4

To get started, you’ll need to head over to the Gitlab page where Xin has made the addon available for free. Here’s a step-by-step guide to downloading and installing the Mixamo addon for Blender 4:

  1. Visit this Gitlab repository: https://gitlab.com/x190/mixamo_blender4
  2. Click on the “Code” button and select “ZIP” to download the addon. Do not unzip the file.
  3. Open Blender 4 and navigate to the “Edit” > “Preferences” menu.
  4. In the “Addons” tab, search for “Mixamo”. If there are any existing Mixamo addons, disable and remove them. Close Blender and reopen it. If you don’t have an existing Mixamo addon you can skip this step.
  5. Go back to the “Edit” > “Preferences” > “Addons” tab.
  6. Click the “Install” button and navigate to the downloaded ZIP file.
  7. Select the ZIP file and click “Install Addon”.
  8. Locate the “Mixamo” addon in the list and install it.
  9. Place a checkmark next to the Mixamo addon to activate it.

With the addon installed, you’re now ready to start using Mixamo in your Blender 4 projects.

NEW: Bone Collections

This fix does not change the Mixamo rig addon’s main functionality. It marely makes it compatible with Blender 4 and beyond. So if you are an experience user, you will feel right at home.

The only significant difference is: Bone Collections.

Blender 4 replaced the old and limited Bone Layers with a completely new Bone Collection system (so long Bone Layers, we won’t miss you! :D). Therefore the Mixamo rig addon was also updated to make use of the new system. 

If you are not familiar with Bone Collections, see my post and video about the updates in Blender 4.0 and 4.1

The addon organizes the rig into three bone collections: “Control,” “DEF,” and “MCH.” These correspond to the Layer 0, 1 and 9 in earlier versions of the addon:

If you are new to the Mixamo Rig addon, you may like my videos on the topic. While they were recorded with the “old” version of the addon, everything still works the same way. Just be mindful of the difference between Bone Layers and Bone Collections mentioned above.

A: The addon is specifically designed for Blender 4 and later versions. If you’re using an older version of Blender, such as 3.6 or earlier, you’ll need to use the official Mixamo addon, which can be downloaded from the official source.

    1. I asked the developer. He said that from the look of the error, you seem to be using the original addon, not the fixed one. Please read the instructions carefully and download the right addon. Also, if you have an existing mixamo addon installed:
      -remove it from Blender
      -restart Blender
      -install the new one

      Hope this helps.
