Mixamo to Rigify in one click, Blender add-on

Dene writes:

Mixamo to Rigify is an add-on for Blender that allows the simple and easy import of Mixamo animations. It automatically creates a metarig, and offers options for importing multiple animations at once and adding them to a single Rigify rig or import as multiple Rigify rigs. The one-click import feature makes it easy to use.

1. No messing with Blender’s metarig, it’s created automatically (you can tweak it later and regenerate Rigify if you want to)
2. One-click - just select mixamo .fbx and click “import”
3. Option to import multiple Rigify’s at once (as individually created Rigify rigs or just one Rigify with multiple animations on it)
4. Option to import multiple Rigify animations to a single Rigify that you already have in the Blender scene

You can get it here.
