What is Auto-Rig Pro?

Auto-Rig Pro is an addon for Blender to rig characters, retarget animations, and provide Fbx export, with presets for Unity and Unreal Engine. First developed as my own in-house rigging tool, i've released it a few years ago and it expanded quickly thanks to great support from the community!

Rig features demo

Getting Started with Auto-Rig Pro:

Youtube Channel - Documentation - Frequently Asked Questions

Rig fast with the Smart feature

For humanoid characters, the Smart feature can automatically place the bones to speed up the process, after adding the green markers. The result remains editable.

Non-humanoid characters can also be rigged without the Smart feature, manually (horse, dog...).

Based on a non-destructive workflow, the final rig remains easily editable anytime after its generation. Check the product documentation and the youtube channel for more informations.

Built for performances, allowing fast animation playback.

Character examples: Mike (free), Anna, Kevin,  Nina and Alex

Important note about skinning: If possible, use water-tight geometry for best auto-skinning results. Knowing the bases of Blender's skinning tools, weight painting, to fine tweak the bones influences is recommended. Read the doc for more informations.

If you encounter any bugs please report it. Updates are free and will remain free. Also make sure to read the FAQ and the documentation to solve common issues.

Modular - Fully Featured

Customize the rig definition in a few clicks: fingers, wings, toes, spine bones, multiple neck bones, tail, breasts, ears and much more. Duplicate or remove limbs to rig spiders, centaurs... or whatever!

3 bones IK for quadrupedal creatures:

Fingers IK-FK:

Intuitive tool to edit the bone shapes, with automatic mirror:

Customizable UI: fully editable layout, buttons positions, colors, background pictures... The picker panel dynamically updates, so you can select any bone from the separate panel easily.


The Remap feature allows retargetting of any armature action to another one, with different bone names and bone orientations, supporting imported .bvh/.fbx armatures for example. It's universal: works with Auto-Rig Pro, Rigify, custom rigs... Define the source armature, the target armature, and the animation will retarget according to the bones names matches and bones original orientation.

It support IK feet, hands for accurate motion tracking, and an interactive offset tool to remap to different characters proportions.

Game Engine Export

Auto-Rig Pro allows export to FBX format via a dedicated module, to proven engines such as Unity or Unreal Engine.

2 export types: Universal to export the skeleton of any creatures, and Humanoid for bipeds only, with options for easy retargetting and root motion.

  • Support of multiple twist bones for optimal volume preservation in game engines, where dual quaternions skinning is not possible (top: single twist bone, below: 4 twist bones)

  • Unit conversion to initialize the scale transforms values to 1.0 in Unity and Unreal Engine
  • Unreal Mannequin compliant: support Mannequin bones hierarchy, bone axes conversion, bones naming
  • Automatic A-Pose
  • Support full facial rig, and advanced bones. "Twist" mode for secondary controllers, wrapped on bendy-bones for smooth curves effects, leading to 1:1 export compatibility in Fbx format

  • "Soft-Linking" for cheap stretchy bone effect, Fbx compliant
  • Actions are baked to the simplified rig
  • Animated shape keys (blend shapes) support
  • Selective/multiple action export
  • Root motion support

Note: Glb/Gltf export is not yet embedded with Auto-Rig Pro, but the Cascadeur to Game Engines addon supports it!

Bring your poses to the next level!

The secondary controllers offer a unique control over the pose. Located all along the limbs, they're dedicated to fine pose sculpting, cartoon effects, bending, stretching, etc. Three deformations mode in option: Twist (exportable to Fbx and bendy-bones based for best compatibility), Additive (exportable to FBX), Bendy-Bones (Blender only).

Just use them instead of corrective shape keys, or as a complement. Below a typical leg bent before and after tweaking the secondary controllers.

Corrective shape keys can be created easily with a dedicated tool supporting IK-FK bone chains:

  • Complete set of secondary controllers for fine pose sculpt
  • Advanced facial setup with automated placement
  • Improved skinning based on Blender's heatmaps. Auto-splitting of multiple elements + voxelization. Compliant with the Voxel Heat Diffuse Skinning addon.
  • Shape keys drivers creation tool
  • Game engines support, FBX: Unity - Unreal Engine. Generic, Humanoid and Universal rig type
  • Bone remapper to retarget any armature action to another one, with different bone names and bone orientations. IK support. BVH, FBX files compliant, e.g. Mixamo animations.
  • Compliant with X-Muscle System for realistic muscles simulation
  • By buying this addon you support my work and the Blender foundation, its developers financially. A part of each sale is donated to them. It's worth a big thank you from the open source community, helping Blender remaining free and accessible for everyone! And obviously you ensure the funds for this addon next new features, bugfix. I'm making my best to constantly improve the beast, based on users requests and my own ideas. Have quick look at the release log below.

  • Rig: New Rig Layers menu, to quickly hide or show rig components: armature layers, bones, collection and objects. Useful to toggle some features of a character (clothes, props...) or show/hide a given set of controllers.
  • Rig: Skull bones are now optional and disabled by default
  • Rig: Interface of rig tools/settings has been improved with imbricated sub-panels for better clarity
  • Rig: Extended maximum arms/legs twist bones amount to 32
  • Rig: By default some secondary controllers were just hidden, leading to display them when revealing all bones (Alt-H), even when Secondary Controllers were set to None. This was a bit of a problem, the code has been refactored to hard-delete and create bones on the fly when clicking Match to Rig.
  • Rig: Renamed internal property to avoid conflict. Required to click the Update button (as prompted automatically) with old armatures

  • Skin: Binding performances significant speed up. Although the weight improvement functions were useful (smooth twist bones weights, refining hips weights...) they were bloated with lots of overhead. Binding is now from 3 to 5 times faster (!) after minimizing Python code overhead and optimizing functions with dedicated built-in operators.
  • Skin: New "Improve Heel Weights" setting to improve automatic skinning in the ankle/heel area
  • Skin: Warning message when binding meshes with more than 150.000 polygons, can be slow

  • Export: Less than 3 spine bones are now supported as Humanoid type (3 was the minimum before)
  • Export: Improved consistency with the actions export dialog, added messages relative to "Only Active" and warn if no actions are exported

  • Remap: Static source bones (not animated) are now supported, they appear in the bones list
  • Remap: When importing a preset, the browser now uses automatic filtering for .bmap format files


  • Export: Overridden and proxy armatures export breakage with Blender 2.93
  • Export: Spine bend bones could not be exported when more than 2
  • Export: Avoid and fix vertex group names conflict
  • Skin: Eyelids weights improvements were broken in some cases



  • Rig: Mirror shape keys + mirror drivers (support corrective drivers, corrective bones)
  • Rig: Set Auto-Stretch to 0.0 by default to new armatures
  • Rig: IK-FK shapes are now scaled with linear interpolation drivers, to ease selection (before, bones were hidden). To apply to old armatures, click "Update Armature" in the Misc tab of Auto-Rig Pro
  • Rig: IK pole position improved when snapping, now in-line with the knees/elbows
  • Rig: New tweak twist setting for arm and thigh bones, to correct bad twisting with extreme arms/legs angles. To apply to old rigs, click "Update Armature"
  • Rig: A log message now reports detailed changes when clicking "Update Armature"

  • Skin: UI Cosmetic change, skinning features as separate engines
  • Skin: Expose new setting: Smooth Twist Weights, Refine Head Weights (aka "Use Chin" previously), Improve Hips Weights
  • Skin: The Voxel Heat Diffuse Skinning addon is now directly embedded as a binding engine (the addon must still be installed separately), supporting post-skinning improvement features of Auto-Rig Pro.

  • Smart: Improved fingers detection with forearm rotated forward
  • Smart: New options to set spine bones count, straight spine, spine troot orientation upward automatically
  • Smart: Improved automatic knee position for IK pole constraints

  • Export: New "Only Selected Bones" option to export only selected bones (Thanks to Jesper for contributing!)
