Drop a rigged character and make it move: pick from 79 free animations, or describe any motion in words. Everything goes into one GLB, in place, ready for your engine.

Drop a rigged 3D model

  • GLB
  • glTF

A humanoid with a skeleton, from Auto-rig, Mixamo or your own rig. Nothing is uploaded: the animations are put on in your browser.

How it works

Each animation was made on another skeleton; it is played on yours by matching the bones by name, the hips, spine, arms and legs, and turning each of your bones as its match turns, so the movement fits your character’s own proportions. The animations are added after any your file already has, each under its own name. No skeleton yet? Auto-rig gives a character one, free.

Motions described in words

Each character was rigged by the free model, then given one description, one run each. The motion was made from the words alone and put on the character's own skeleton; each picture catches it partway through.

Wave and sit

  • “A person waves hello with the right hand, then sits down cross-legged on the ground.”

Questions

What can I animate?
A rigged humanoid as a GLB or glTF: a character from Auto-rig, Mixamo, Blender or a game's own rig. Its bones are matched by their names, so Mixamo's, Unreal's, Unity-style, Tripo's, Meshy's, Rodin's, KayKit's and Quaternius' skeletons all work. No skeleton yet? Auto-rig gives the model one, free. Animals are not animated here yet; a four-legged animal rigged by Rodin in Auto-rig comes with a walk and a run of its own.
Where do the free animations come from?
From Quaternius' Universal Animation Library 1 and 2, released under CC0: free to use in anything, with no credit needed. 79 of them, from walks, jogs, rolls and ninja jumps to sitting, talking, punches, sword combos, spells and farm work. They are put on your rig in your browser, so nothing is uploaded and there is no daily limit.
How does a motion described in words work?
Hunyuan Motion, Tencent's text to motion model, makes the movement of one person from your sentence, up to 12 seconds long, and we put it on your rig. It works best in English, for one person moving, without animals, props or a second person. A motion is 15 credits.
Are the animations in place?
Yes. The hips rise and sink as the movement needs, but stay over the spot the character stands on, so a walk or a run plays on the spot and your game or engine moves the character itself, as with Mixamo's "In Place".
Is it an alternative to Mixamo?
For animations, yes: it works on any humanoid rig, not only one Mixamo made, with no account, and a motion it has no clip for can be described in words. All the animations you add go into one GLB, each by name.
What does it cost?
The animation library is free, with no account and no limit. A motion described in words is 15 credits. One credit is one cent, from $15, with no subscription. A run that fails gives its credits back.
What happens to my file?
With the animation library, nothing leaves your browser: download the result before you close the page. A motion described in words sends your rig to our server and your words to Hunyuan Motion; the animated model is kept in your account so you can download it again.
Do I need an account or to sign up?
No. No sign-up, login or email is required, and there is no limit: the tool runs in your browser, so there is nothing to meter. Use it as often as you like, on as many files as you like.
