AI Rigging & Animation
Updated May 2026
The Rigging tool adds a skeleton (rig) to your 3D character model so it can be animated. The AI detects the body structure, places joints, and assigns skin weights automatically. Instead of hours of manual work in Blender or Maya, you get a fully rigged model in minutes.
It supports humanoid characters, quadrupeds, birds, serpentine creatures, and more. You can also apply one of 12 preset animations directly, or export the rigged model for custom animation in your preferred tool.
Open the AI Rigging and Animation Tool
Providers
| Provider | Credits | Features |
|---|---|---|
| Prism | 20 | All creature types (biped, quadruped, avian, serpentine), GLB/FBX export, Mixamo-compatible rig |
| Meshy | 15 | Humanoid characters only, includes walk and run animations |
Pre-Rig Check
Before spending credits, you can run a free pre-rig check. Upload your model and the tool analyzes whether it can be rigged and which rig type it recommends. This saves you from wasting credits on models that are not suitable for rigging.
How It Works
- Upload your 3D model (GLB or FBX)
- Run the free pre-rig check to confirm it is riggable
- Select your provider and rig type
- Click Rig Model and wait about 1-2 minutes
- Preview the result in the rigged model viewer
- Download the rigged model or apply animations

Animation Presets
After rigging, you can apply any of 12 preset animations to your model. Each animation costs 15 credits and uses retargeting to map the motion onto your specific character’s proportions.
The available presets are:
| Animation | Animation | Animation |
|---|---|---|
| Idle | Walk | Run |
| Jump | Dance | Wave |
| Salute | Boxing | Sword Slash |
| Sitting | Yoga | Celebration |

Rigged Model Viewer
The built-in viewer lets you inspect and play back your rigged model:
- Skeleton overlay to see joint placement
- Play/pause animation playback
- Scrub through the animation timeline
- Speed controls to slow down or speed up playback
- Lock position toggle to keep the model centered during movement animations
Tips for Best Results
- T-pose or A-pose models rig best. Arms extended outward gives the AI clear separation between limbs and torso.
- Textured models are preferred. Surface details help the AI identify body parts more accurately.
- Humanoid characters get the best results across both providers. For creatures, use Prism.
- Single-mesh models work better than models with many separate parts. Consider running Segmentation in reverse if your model is too fragmented.
- Clean geometry matters. If your model has messy topology, run Remesh first.
Export
Rigged models export as GLB or FBX with the skeleton and skin weights embedded. Prism rigs follow the Mixamo specification, so they work directly with Mixamo’s animation library and most game engine humanoid animation systems (Unity Humanoid, Unreal Mannequin retargeting).
What’s Next
After rigging, you can apply textures if your model needs them, or head to your Dashboard to manage your rigged models.

Frequently Asked Questions
How much does AI rigging cost?
Auto-rigging in 3D AI Studio costs 15 to 20 credits depending on the provider. Prism costs 20 credits and supports all creature types including biped, quadruped, and avian. Meshy costs 15 credits but only handles humanoid characters. Each animation preset applied afterward costs an additional 15 credits.
Can I rig non-humanoid characters like animals or dragons?
Yes. The Prism provider in 3D AI Studio supports biped, quadruped, avian, and serpentine body types. Select the matching skeleton type when you rig, and the AI adapts bone placement to your creature’s anatomy. For four-legged animals, choose quadruped. For birds or winged creatures, choose avian.
Do I need to put my model in T-pose before rigging?
T-pose or A-pose models produce the best results because the AI can clearly separate the limbs from the torso. However, it is not strictly required. 3D AI Studio can rig models in other poses, but you may get less accurate joint placement and skin weights on characters with arms close to the body.
Is the rig compatible with Mixamo animations?
Yes. The Prism provider in 3D AI Studio generates rigs that follow the Mixamo bone naming convention. This means you can take your rigged model and apply any animation from Mixamo’s library directly. The rig also works with Unity’s Humanoid animation system and Unreal Engine’s mannequin retargeting.
Can I use my own custom animations instead of the presets?
Absolutely. Export your rigged model from 3D AI Studio as FBX with the skeleton and skin weights embedded. Then import it into Blender, Maya, or your game engine of choice and apply any custom animations you create. The preset animations are optional, just a quick way to test and get started.
What should I do if the pre-rig check says my model is not suitable?
The pre-rig check in 3D AI Studio analyzes whether your model’s geometry is clean enough for rigging. If it fails, try running Remesh first to fix topology issues, or check that your model has clearly defined limbs and is not too fragmented. Single-mesh characters in a neutral pose have the highest success rate.
