Rig it
Open your model in the 3D editor and click Auto Rig (30 credits). It works out what the model is, places the skeleton and binds the mesh, in about 30 seconds.

Add moves
Click any ready-made move to add it, free. Each one is fitted to your model's own skeleton and proportions, so a short goblin and a tall wizard both walk right.
Describe the rest
Type any move, like "swing a hammer overhead" or "wag its tail", for 20 credits. Then copy it onto your other models for free.

Ready for your engine
GLB files
Download the rigged model and its moves as GLB. Godot, Three.js and Babylon.js load it directly; Unity and Unreal through their glTF importers.
Or 2D sprites
Turn any move into a sprite sheet from 1, 4 or 8 directions with the free 3D model to sprite sheet tool.
Straight into a game
Building your game with Claude Code, Codex or Cursor? The Voidless MCP server rigs and animates models from your editor, and the agent drops them straight into your project.
Questions about 3D rigging and animation
What does it cost?
Auto Rig is 30 credits. Ready-made moves and copying a move to another model are free. A move you describe is 20 credits. 100 credits cost $1 CAD, and failed jobs are refunded.
Which models can be rigged?
Humanoid characters, four-legged animals and props with moving parts, like chests, doors, trees and vehicles. Models made with the Voidless 3D generator work best: they face forward, and characters come out in a T-pose.
Can I rig a model I made elsewhere?
Yes. Upload the GLB with the upload button on the 3D generator (or the MCP's upload_3d_model tool): it opens on its own page, ready to rig, animate and turn into sprites. Or drop it into the 3D model to sprite sheet tool and click Rig it. Draco or meshopt compressed files need exporting again without compression.
Do the moves loop?
Idle, walk, run and dance loop seamlessly. The others, like jump, attack and death, play once.
Can I use the animations in a commercial game?
Yes. You own what you make and can use it in games you sell. See the Terms of Service.
How is this different from Mixamo?
Mixamo only rigs humanoids and you upload and download by hand. Here the same model is generated, rigged and animated in one place, animals and props included, and you can describe moves that aren't in any library.
