AI Rigging

Auto Rig Any 3D Model in Seconds

Meshy's AI auto rigging tool builds the full skeleton and skinning weights for any 3D character — online, in under 30 seconds. Free to start with 100 credits every month, no credit card, nothing to install.

How to Auto Rig 3D Models Online

AI rigging is the automated process of generating a bone hierarchy and skinning weights for a static 3D model so it can be animated. Meshy runs both stages in your browser, typically in under 30 seconds.

  1. Upload or Generate Your 3D Model

    Start with your own character (FBX, OBJ, GLB), or generate one with Image to 3D or Text to 3D and rig it directly — no exports or re-imports. A clear T-pose or A-pose gives the most accurate rig.

  2. Auto-Rig & Preview

    Meshy detects the body plan — humanoid, quadruped, or smart-rig — builds the full bone hierarchy, and computes smooth skinning weights in under 30 seconds. Check the skeleton with the bone overlay before you commit.

  3. Download & Export

    Export your rigged 3D model as FBX or GLB with bones and weights intact, ready for Unity, Unreal Engine, Blender, and Godot. Or apply any of 600+ animation presets in the same panel.

Why Choose Meshy's AI Auto Rigging Tool

Full Bone Hierarchy

Every rig ships with a clean, logically structured skeleton. Joint chains follow industry conventions, so the hierarchy reads correctly in any engine or DCC tool.

AI Skinning Weights

Smooth, deformation-ready skin weights, computed automatically — no more hours of manual weight painting per character.

600+ Animation Presets

600+ game-ready animation presets — walking, attacking, idle poses, and more — ready to apply to any rigged character.

Humanoid, Quadruped & Custom Skeletons

Meshy's 3D character rigging handles humanoids, quadrupeds, and fantasy creatures. The AI detects the skeleton type from your mesh — no template to pick.

Built-in Bone Editor

Fine-tune bones and skinning weights right in the browser before you export. Prefer your own tools? The rig imports into Blender or Maya with the hierarchy and vertex groups intact.

Mixamo-Compatible Naming

Bone names follow Mixamo's conventions. Upload your rigged character to Mixamo and apply any motion clip directly — no renaming, no plugin.

What Types of 3D Models Can You Auto Rig?

One auto rigger covers every body plan. Skeleton rigging previews straight from the Meshy viewer: humanoid, quadruped, and smart-rig.

Smart Rig

Rig 3D Models for Unity, Unreal, Blender & Godot

Auto-rigged models export as FBX or GLB with the full bone hierarchy and skinning weights preserved.

Unity

Drive characters with the Animator Controller and Humanoid motion clips. Skeleton maps to Unity's Humanoid Avatar.

Unreal Engine

Import as a Skeletal Mesh, driven by Control Rig or Sequencer. Compatible with Unreal's retarget pipeline.

Blender

Bones import as a Blender Armature with vertex groups intact. Full armature editing and NLA animation.

Maya & 3ds Max

Skeleton structure works with Maya's HumanIK solver and MotionBuilder. Full hierarchy and weights preserved in 3ds Max.

Godot & Roblox

Native FBX / GLB import via ufbx in Godot 4.3+. Build Roblox games with AI-rigged characters via the Meshy Bridge app.

Omniverse & More

USD-compatible pipeline for NVIDIA Omniverse. Need a different format? Use the free 3D file converter.

Frequently Asked Questions

Auto rigging in Meshy typically completes in under 30 seconds for a standard character. Complex characters with non-standard proportions may take a few minutes longer. End to end, the full character auto-rigging workflow — from a static mesh to a downloaded, fully rigged character — usually takes just a few minutes.

Yes. Every Meshy account includes 100 free credits each month for 3D model rigging online, with no credit card required. Meshy works as an auto rigger online: everything runs in the browser, nothing to install. For higher volume, teams, or private commercial licensing, see the pricing page.

Yes. Meshy generates skeleton naming that matches Mixamo's bone conventions, so you can upload your rigged character to Mixamo and apply motion clips from its library directly. Inside Meshy you also get 600+ animation presets without leaving the page.

A clear T-pose or A-pose with distinct limb separation gives the most accurate auto rig, and a clean pose helps auto skinning compute smooth weights. If you create the character with Text to 3D or Image to 3D, prompt for a T-pose so the output is animation-ready from the start. Models under 100K faces rig faster and perform better in game engines.

Upload FBX, OBJ, or GLB. Rigged models export as FBX or GLB with the full bone hierarchy, skinning weights, and animation data preserved. Choose FBX for game engine pipelines and GLB for Blender, web, and AR/VR work. Need a different format? Run the export through the free 3D file converter.

The fastest path is Meshy's Remesh, which rebuilds clean quad-dominant topology with edge loops at the joints and re-unwraps UVs at a controllable polycount. For specialist character work that needs precise loop control, export an OBJ to Blender and use an add-on like RetopoFlow against the high-poly source. After retopo, re-bake or re-run AI texturing on the new mesh, then auto-rig it in Meshy — the auto rigger doubles as a topology validator: if the rig succeeds, your mesh is animation-ready.

Meshy's Animate panel plays the rigged character live in the browser, with rotation, zoom, and a toggleable bone overlay, so you can check joint placement and deformation before downloading. Outside Meshy, the Babylon.js Sandbox and glTF Viewer both play GLB animations and show skeleton joints, and Blender gives you full rig inspection including weight paint mode.

Meshy's auto rigger builds the full body skeleton; detailed facial rigs with jaw, eye, and mouth controls are still a manual step in Blender or Maya. For the cleanest facial deformation later, generate the head with a clear facial reference (front or 3/4 view) so eye sockets and mouth corners are well-defined, and keep a neutral expression. The body hierarchy and vertex groups import intact, so refining the face rig in your DCC is straightforward.
