Auto Rigger
Upload a GLB, FBX, or OBJ model and get back a fully rigged version with optional preset animations baked in. The auto rigger builds the skeleton for you, so there's no manual bone placement and no Blender or Mixamo round-trip. Works on the static models from our 3D Model Generator and on any clean humanoid or quadruped you bring.

Drop in a GLB and get back a fully rigged version with optional preset animations.
Features
- Upload your own model — GLB, FBX, OBJ, up to 30 MB
- Biped, quadruped, and auto detection — handles humanoid characters and four-legged creatures
- Preset animations — idle, walk, run, jump, slash, shoot, climb, hurt, fall
- GLB output — drops straight into Three.js, Babylon, Unity, Godot, or Blender
Tips
- Use a clean model without existing rigging or animations
- For characters facing the wrong way after rigging, try the −90° rotation correction
- Pick fewer animations for faster turnaround. Walk-only is the fastest option.
- Want a custom motion (not just presets)? Use Prompt Animations and retarget the BVH onto your rigged model right in the browser.
How does automatic rigging work?
You upload a model and the auto rigger detects whether it's a biped or quadruped, fits a skeleton to the mesh, and binds the vertices so the model deforms correctly when it moves. You can then bake in preset animations. The whole pass runs online, so you skip manual weight painting.
What 3D model formats can I rig?
You can upload GLB, FBX, or OBJ models up to 30 MB. The rigged result comes back as GLB, which drops straight into Three.js, Babylon, Unity, Godot, or Blender.
Is the auto rigger free?
Yes. You can auto-rig a model in the browser and download the GLB result. Sign in to save your rigged models.
