Mixamo to Blender: auto-rig a character, download animations and import them

Mixamo gets a humanoid character moving without building a skeleton by hand. This guide walks through the whole Mixamo to Blender workflow: the Adobe account, the auto-rigger, the download settings, the import, chaining animations in the NLA editor, and the problems people run into. Blender settings come from the Blender 5.2 manual and release notes.

What is Mixamo?

Mixamo is an Adobe web service that runs in your browser. It bundles three tools: a library of characters that are already rigged, a library of animations to apply to them, and an auto-rigger that builds a skeleton for your own model.

Adobe’s FAQ sets one firm limit: the auto-rigger and the animations are for bipedal humanoids only. A character with a clearly separate head, torso, two arms and two legs works. Wings, tails or extra limbs can make the rigging fail.

Is Mixamo free? License and account

Per Adobe’s FAQ, Mixamo is free for anyone with an Adobe ID. There is no Creative Cloud subscription to buy and nothing to purchase. The one catch: it is not available for Enterprise or Federated IDs, the accounts a company or school manages for you.

Characters and animations can be used royalty free in personal, commercial and non-profit projects. Adobe’s examples include illustration, 3D printing, films and video games. The FAQ covers using them in your own work; if you plan to sell or redistribute the files themselves, read Adobe’s terms of use first.

Setting up a Mixamo account

1. Go to mixamo.com.
2. Sign in with an Adobe ID, or create one.
3. If your Adobe login is managed by your employer or school, Mixamo will not accept it. Use a personal Adobe ID instead.

How to use the Mixamo auto-rigger

Step 1: prepare the character in Blender

Adobe’s FAQ lists what makes auto-rigging succeed or fail:

• A neutral pose, T-pose or A-pose. A character that is already posed, or strongly asymmetric, may rig badly. The T-pose guide for Blender shows how to get back to one.
• The character at the world origin, at (0, 0, 0).
• Nothing else in the file: no camera, no light, no helper objects.
• No floating parts, such as a head detached from the body, and a clean mesh.
• No large extras: long hair, loose clothing, wings or a tail can block the auto-rigger.

Then export with File > Export > FBX (.fbx). To send textures along, set Path Mode to Copy and turn on Embed Textures, the package icon right next to it, which only works in Copy mode. Mixamo also takes OBJ files, but without textures, so the character shows up gray. The workaround is a ZIP containing the .obj, the .mtl and the texture images.

Step 2: upload the model and place the markers

1. On Mixamo, click Upload Character and pick your FBX, OBJ or ZIP file.
2. Drag the markers onto the points shown, such as the wrists, elbows, knees and groin, following the on-screen prompts.
3. Confirm. Rigging starts and usually takes a few minutes.
4. When it is done, Download saves the rigged character and Find Animationsopens the animation library.

Step 3: check the rig

Apply a first animation and watch the character move. If a shoulder twists or a hand drags the hip along, go back to the checklist above: a pose that is not neutral, asymmetry, a detached part. Fixing the model in Blender and uploading it again is usually less work than repairing weights afterward. When a touch-up is still needed, our weight painting guide shows how.

Downloading Mixamo animations

Pick an animation in the library and it is applied to your character right away. The settings panel then lets you adjust parameters such as speed and arm spacing. For walks and runs, the In Place checkbox, when it is offered, keeps the character on the spot. That is what you want for a loop, or when you plan to move the character yourself in Blender.

Click Download and set up the dialog:

• Format: FBX, which Blender imports directly.
• Skin: With Skin includes the mesh, Without Skin keeps only the animated skeleton. Use With Skin for the first animation and Without Skin for the rest, so the character mesh is only imported once.
• Frames per second: match your scene’s frame rate, set in Output Properties, Format panel, Frame Rate.

Importing Mixamo into Blender: File > Import > FBX

Since Blender 5.0, File > Import > FBX (.fbx) runs a new importer written in C++, first shipped as experimental in Blender 4.5. Of the options described in the Blender 5.2 manual, three matter for a Mixamo character:

• Scale: a scale factor applied to the imported objects, around the world origin.
• Animation: the panel checkbox imports the animation, and Offset shifts it by a number of frames.
• Ignore Leaf Bones: skips the last bone of each chain, which only marks the length of the bone before it. According to the Blender 4.5 release notes, the option keeps leaf bones that actually deform the mesh.

Each take in the FBX file becomes an action, and each animated object gets its own slot in it. The old importer is still in the menu as FBX (.fbx) (Legacy), but the manual marks it as deprecated. That is where Automatic Bone Orientation and Force Connect Children live. The 4.5 release notes explain why they were left out of the new importer: Force Connect Children often wrecks animated armatures.

Check the armature scale

Select the armature, open the sidebar with N, go to the Item tab and read Scale. A value of 0.01 comes from converting a file in centimeters to Blender’s meters: the importer puts that conversion on the top-level object. The character looks the right size and the animation plays correctly.

Do not apply that scale on an armature that is already animated. The manual is explicit: applying transforms to an armature does not affect pose locations or animation curves, and it recommends applying transforms before rigging and animation. The hip movement would no longer match the new scale. To resize the character, change the object scale and leave it unapplied.

Combining multiple Mixamo animations in Blender

Blender stores animation in actions, reusable data-blocks. The Nonlinear Animation (NLA) editor lays actions out as strips on tracks that stack like layers.

1. Import the character (With Skin), then each animation (Without Skin). Every import adds an armature carrying its own action.
2. Select your character’s armature. In the Dope Sheet, Action Editor mode, pick the imported action from the Action data-block menu in the header. If the Slot field stays empty, choose the slot yourself: Blender only fills it in when it finds a slot with a matching name and type.
3. In the NLA editor, click Push Down Action. The action becomes a strip on a new track.
4. Repeat for every animation, then arrange the strips one after another with G, which moves them in time or to another track.
5. Delete the extra imported armatures. Their actions stay alive because the strips use them. An action that nothing uses is removed when you save, unless it has a Fake User, the shield icon. The FBX importer gives one to every action it creates.

Blends and loops

• Blend In and Blend Out, in the NLA sidebar, Active Strip panel: how many frames a strip takes to ramp its influence up and down. Auto Blend In/Out works them out from strips that overlap it on the track above or below.
• Transition: select two neighboring strips on the same track, with a gap between them, then Add > Transition (Shift+T). The transition fills the gap and Blender interpolates from one to the other.
• Repeat, in the Action Clip panel, plays the action several times, which suits a walk cycle. The walk cycle guide explains how a clean loop is built.
• To edit an action that is already a strip, select it and press Tab for Tweak Mode.

Troubleshooting Mixamo in Blender

• The character is tiny or huge: set Scale on import, or change the armature object’s scale. Do not apply scale on an animated armature.
• The action does nothing: either the slot is empty or the bone names do not match. An action drives bones by name, and Mixamo prefixes its bones, as in mixamorig:Hips. A file from another source, or with a different prefix, will not move a single bone. Rename the bones or use a retargeting tool.
• The character slides or snaps back: with In Place, the object’s movement has to match the stride. Without In Place, the walk moves forward on its own, but each repeat starts again from the beginning. Pick one approach and stick with it for the whole sequence.
• Small extra bones stick out at the end of chains: reimport with Ignore Leaf Bones.
• Shoulders or arms deform badly: the uploaded model was not in a neutral pose, not symmetrical, or had detached parts. Fix it and run the auto-rigger again.

Mixamo limits and alternatives in Blender

The Mixamo skeleton is built to play its own animations. To pose a character by hand, with controls and inverse kinematics, you need an animation rig. And for anything that is not a biped, Mixamo is not an option.

• Rigify ships with Blender and is documented in its manual. It generates a full rig with FK and IK controls from a starting skeleton: human, quadruped, cat, wolf, horse or shark. It does not bind the rig to the mesh, so skinning is still on you. The Blender rigging guide covers the process.
• Auto-Rig Pro is a paid add-on by Artell. Its Smart feature places a humanoid’s reference bones in a few clicks, from a T-pose or an A-pose. Its Remap tool retargets an animation from one armature to another, with built-in presets for Mixamo skeletons when the target is an Auto-Rig Pro rig. Quick Rig turns an existing skeleton into an Auto-Rig Pro rig with controls.

Once the animation is locked in, it still has to be rendered. The guide on how to render an animation in Blender covers image sequences and video output, and how to render in Blender helps you pick between Cycles and Eevee. For keyframes and interpolation, see the Blender animation guide.
