Make sure to set these actions to fake users enable the shield so they aren't deleted when we close Blender.

Repeat the previous step for each animation, each of these will be a separate action.Select the control rig and in the Mixamo tab set the source skeleton to the animation armature then click Apply Animation to Control Rig. If we are importing animations follow the previous step for importing but this time importing the animation.

In scene view select the imported armature and press N. Back in Blender first go to file > import > FBX and import the default model.If exporting animations, export each animation with the skinning option set to no skin.Once the model is ready export it without any animation or pose. In Mixamo upload a character and rig it if necessary.Next download and Install the Mixamo add-on for Blender in Edit > Preferences > Add-ons > Install, make sure to enable the add-on.

These are the steps we need to take when using Mixamo in Blender Now we can close the preferences window and in the 3D view press N to bring up the side panel. Blender will pause for a second and then the add-on list should shorten to the Mixamo add-on we just installed and then we can enable it. Mixamo uses Fbx which they don't really understand and worse keep changing so that creates errors in reading the bone rigs between Mixamo and what ever 3rd party software you try to load your animation into, things like crossed arms, folded skin, and busted animations are all caused by Fbx being misread and the fact of the matter is Autodesk does this by design so the point of this addon i use is simple.The browser window should close automatically and we'll now be back at the add-on list. Now if you want to share the model I may suggest which rig to use but at this point only you can answer that

you can add bones to a Mixamo rig with face being the most common so you can animate a smile now that Adobe ripped out the blend shape system but you can't upload your own bones if they do the same thing as Mixamo bones i.e, Mixamo will not replace bones.

ok all Mixamo rigs are the same but for the hand i.e, 5 digits vs a claw or nothing.
