What is Auto-Rig Pro?
Auto-Rig Pro is an all-in-one solution to rig characters, retarget animations, and provide Fbx export for Unity and Unreal Engine. First developed as my own in-house rigging tool, i've released it a few years ago and many new features have been added since then.
Want to try first? Download Mike, free character rig here.
Getting Started with Auto-Rig Pro:
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...).
Built for performances, allowing fast animation playback.
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.
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!
Video tutorial, rig a centaur with the multi-limb feature: Centaur Rig
Wings limb for advanced feathers rig:
Spline IK limb to rig ropes, tentacles, IK spine...
3 bones IK for quadrupedal creatures:
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.
Additionally, to animate over a motion capture action on an additive layer, check the additive keyer addon (free)!
Game Engine Export
Auto-Rig Pro allows export to FBX format (GLTF is being worked on as well) via a dedicated module, to proven engines such as Unity or Unreal Engine.
3 export types: Universal to export a simplified bones hierarchy for any creature, Humanoid for bipeds only, with options for easy retargetting and root motion, and Generic to export the deforming bones and the non-deforming ones if they are parent of the deforming bones.
- 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
- Actions are baked to the simplified rig
- Animated shape keys (blend shapes) support
- Selective/multiple action export
- Root motion support
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:
Tell Me More!
Extensive list of what the addon has to offer:

- Apply Pose as Rest Pose feature to quickly change the rest pose of the character, aligning reference bones on it and applying armature modifiers in a single click
- Modular: only rig what you need. Fingers, toes, ears, breast, adjustable amount of spine, neck, twist bones, tail, and neck bones... Duplicate, remove limbs to rig creatures with multiple arms and legs.
- Fingers auto-rotation option: bend when scaling the first phalange, pre-defined fist pose
- Easy controller shape edition
- Bone picker: Can be turned on/off, import/export presets. Customizable.

- Bend all fingers in one click (fingers grasp), fist pre-defined pose, auto rotation of fingers phalanges from scale
- IK/FK eyes
- Auto-eyelid rotation
- Multiple Child-Of constraints support for the IK hands and feet to change their parent space any time (e.g. if the character is driving a car, hands on the wheel, then grab the car door)
- 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.

- 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. You receive a notification when the addon is updated, and download it for free.
Make sure to uninstall the current addon before installing the new one and restart blender.
- New Bendy bones chains
- Automatic IK constraint setup if the target rig has no IK constraint
- New tool to Freeze the target armature
- The Generic export has been removed, leaving only Humanoid and Universal: it was leading to many problems and was not that used.
- Multiple neck bones are now supported for the humanoid export
- 20% speed improvement when exporting humanoids for Unreal with Mannequin bones orientation
- Issue with the new tail settings
- Duplicating ear bones was only duplicating 2 bones
- Meshes with delta transforms were not compatible
- "Initialize Armature Rotation" was broken
- The dummy mesh when exporting the armature only was no more added in the Fbx file
- Exporting multiple actions with root motion could lead to incorrect root position
- The custom bones list was not initialized
- Disabling the humanoid action only for export was leading to an error when baking shape keys
- Mannequin spine bones orientation issues
- New "Spline IK" limb, to add generic spline ik chains. Adjustable amount of bones, bendy-bones per bone, and the side can be set (left, right, middle). Useful to rig ropes, strings... Can be used to replace the current FK spine: it's recommended to keep one spine bone for the pelvis area ("c_root_master.x" and "root.x" bones), and parent the Spline IK to it.
- New "3 bones leg" in option, adding another leg bone at the root. New property "3 Bones IK" to enable IK on 3 or 2 legs bones. Made it compliant with IK-FK snapping.
- Duplicate limbs now works with duplicated limbs as well (was restricted to original limb before)
- After adding a new limb, the reference bones are now selected
- The Corrective Shapes tool is now universal, it can be used for any bones, not only arms or legs bones. If one bone is selected, it must be an arm or leg bone since this is optimized for these limbs. Otherwise, two bones must be selected as input for the driver angle setup.
- The Bind button is now compliant with any armature, not only Auto-Rig Pro armatures
- New "Scale Fix" button to automatically fix the scaling issue (as mentioned in the FAQ). If binding does not work, enable it.
- Added 3 fingers detection
- New frame range option to Retarget only a specific frame range
- New "Bind/Unbind Only" options to test the retargetting before baking it, to save some time
- Apparently identical class names could cause installation error in some cases, the classes have been renamed to avoid it.
- Armature object scale was not properly supported
- Issue with objects containing shape keys
- The eyelids bones roll could be wrong
- Smart facial detection error
- New Corrective Shapes tool, to easily setup corrective shapes driver. (See doc)
- The 0, 1 and Reset buttons of the Shape Keys Driver tools have been refactored to work with more cases, such as these corrective drivers using bones rotational difference.
- New Bake IK/FK tool, to snap IK to FK arms and legs and vice versa over a specified frame range
- Improved root/hips bone skinning by restraining the thigh influence near the root bone
- The c_neck_01 controller is now removed when secondary controllers are set to None, to improve compatibility with Fbx export
- The first eyebrow bone was not deforming anymore by default
- The new "Reset All" button did not work when Auto-Rig Pro was not installed, with the "rig_tools" addon only.
- Adding a new armature now deletes any existing rig_add or custom shapes in the scene, to avoid errors
- The new corrective driver shape tool had issues with X-mirror
- Issue with keyframed objects
- Issue with objects containing shape keys
- The eyelids bones roll could be wrong
- The subsurf modifier was not disabled properly when shape keys are used
