AI rigging automatically adds a skeleton (armature) to a 3D model so it can be animated. Traditional rigging requires hours of manual bone placement, weight painting, and testing. AI rigging analyzes your model's geometry and places bones, assigns skin weights, and generates a control rig in minutes, making 3D animation accessible without specialized rigging knowledge.

Upload a GLB file, and the tool first analyzes the model to check if it's suitable for rigging. It then automatically places bones based on the detected body type, computes skin weights for natural deformation, and generates a Mixamo-compatible rig. You can preview animations directly in the 3D viewer before exporting as GLB or FBX.

The tool supports multiple rig types including biped (humanoid characters), quadruped (four-legged animals), hexapod, octopod, avian (birds), serpentine (snakes), and aquatic creatures. Each rig type places bones appropriate for that body structure. For best results, models should have clear limbs and a recognizable body shape.

For best results, humanoid models should be in a T-pose or A-pose with arms extended and legs slightly apart. This gives the AI clear limb separation for accurate bone placement. Models with arms at their sides or in complex poses may produce less accurate rigs. The analysis step will flag potential issues before rigging begins.

Export rigged models as GLB or FBX. GLB works well for web applications, AR experiences, and three.js projects. FBX is the standard for Unity, Unreal Engine, and professional animation software like Blender and Maya. The exported rig is Mixamo-compatible, meaning you can apply Mixamo animations directly or retarget animations from other sources.

AI rigging is available on paid plans. The tool uses credits from your 3D AI Studio subscription, with plans starting at $14/month. The workflow includes model analysis, automatic rigging, and animation preview. You can rig models generated in 3D AI Studio or upload your own GLB files from external 3D software.
