There are currently two versions available for download:
- 3.40 is the latest stable release for Blender 2.79, with all features.
- 3.41 is an experimental release for Blender 2.8, it's not production ready! There are missing features, bugs. It's only for testing and experiments, for informed users who want to play with the rigs in the not-finished-yet Blender 2.8.
What is Auto-Rig Pro?
Auto-Rig Pro is a set of tools to rig characters, retarget animations, and provide Fbx export for Unity and Unreal Engine.
Getting Started with Auto-Rig Pro:
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. For character made of multiple separate parts, it's best to use the Voxel Skinning addon.
Due to recent API changes, Blender 2.79 is required.
Rig fast with the Smart feature
Position the reference bones so that they match your character proportions. To speed up this process, the smart tool will automatically try to find the body parts locations for you (bipeds only so far). Then, edit the result if needed (if your character is not a biped/ or for more accuracy), eventually place the facial bones and other extra limbs, and generate the final rig. Based on a non-destructive workflow, the armature remains easily editable anytime after the generation. Check the product documentation and the youtube channel for more informations.
Customize the rig definition in a few clicks: fingers, toes amount, spine bones, multiple neck bones, tail, breasts, ears and much more. Duplicate or remove limbs to rig spiders, centaurs... or whatever!

The picker panel dynamically updates, so you can select any bone from the separate panel easily.
Intuitive tool to edit the bone shapes, with automatic mirror:
Customizable UI: fully editable layout, buttons positions, colors, background pictures...
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 via a dedicated module, to proven engines such as Unity or Unreal Engine, and probably others not yet tested. Shape keys are transferred as well.
Three 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.
- Twist bones included in option
- Unit conversion to initialize the scale transforms to 1.0 in Unity and Unreal
- Unreal Mannequin bones hierarchy and naming in option
- Full facial, and advanced bones such as tweak bones
- Actions baked on the simplified rig
- Selective action export
Bring your poses to the next level!
The additive weights controllers offer a unique control over the pose. Located all along the limbs, they've been developed using an innovative system to operate on a second layer of deformation, for fine pose sculpting, cartoon effects, bending, stretching, etc. Two deformations mode in option: Additive (exportable to FBX) and Bendy Bones.
Just use them instead of corrective shape keys, or as a complement. Below a typical leg bent before and after tweaking the secondary controllers.

- 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.
Migration to Blender 2.8 started
[WARNING!] 3.41 is currently an alpha version: it means it's not ready yet, there may be bugs, crashes. Especially since Blender 2.8 itself is still in alpha stage!
It should not be used for production or serious projects. It's only for testing and experiments, for informed users who want to play with the rigs in Blender 2.8. The latest stable release is the 3.40s version for Blender 2.79, download and use it for production usage.
Only the main module of Auto-Rig Pro has been ported. The Remap, Smart, and Fbx export modules will be brought to 2.8 later.
New or improved:
Rig: New "Empty" armature to build a rig from scratch, instead of starting from a biped/quadruped basis. New button to add limbs. New button to adjust the selected limb parameters.
Rig: Disabling a spine bone no more disables the neck and head limbs as well
Rig: Ears bones amount can now be adjusted
Rig: Neck bones amount of duplicated necks can now be adjusted
Rig: The auto-eyelid rotations are now constrained to avoid aberrant angles
Rig: Update Armature now show an informative line to warn the user to click Match to Rig afterward
Picker: Errors are now better handled, if the target bone is not found or a bone shape is missing, the error is skipped
Fbx Export: Actions can now selectively be removed before exporting
Fbx Export: Root motion option is now available for Universal type
Fbx Export: The simplify value is now set to 0.05 by default, to avoid rotation issues of IK chains.
Fbx Export: Some single limbs could prevent export to work
Fbx Export: "Fix Fbx Bones Rotations" could lead to issues
Fbx Export: Renaming for UE and exporting the tail as humanoid could lead to wrong parenting
Fbx Export: Exporting only the armature now adds a dummy mesh for correct export
Fbx Export: Multiple ears bones are now exported as Humanoid
Fbx Export: New "Fix Bones Matrix" checkbox in rare cases of incorrect bones rotations export
Rig: The ear bones could not be disabled, breast bones did not deform by default
Remap: Cancelling the Redefine Rest Pose could not work as expected, fixed the copy bones orientations feature
Remap: Improved Auto-Scale feature
This update changes some bones orientations (jaw, eyelids) which breaks existing facial animations for these given controllers. It takes effect when clicking "Update Armature" to update older armatures, which is also necessary to make it compatible with the Fbx exporter.
Do not install this version and do not update the armature if you previously rigged characters and need to preserve their facial animations.
New or improved:
Rig: For easier control, the jaw and eyelids controllers are now meant to be primarily translated up/down, instead of rotated. Additional rotation on other axes is still allowed though. The jaw custom shape has been changed as well.
Rig: The tail bones amount can now be adjusted from 1 to 32. When more than 1 bone, a master controller is added as well to rotate all tail bones at once.
Adjustable ears bones will be implemented later.
Rig: Mirroring custom shapes was not working if the shapes were not selectable
Rig: Changing the neck bones amount was accidentally disabling the picker
Rig: Fixed multi-limbs issues and drivers updates
Fbx Export: Objects with multiple armatures modifiers containing the same target could be duplicated several times
Fbx Export: The "knee_bend" weights are now clamped to the "leg_stretch" weights to improve deformations
Fbx Export: Transferring vertex groups could fail if the target group did not exist on the object
New or improved:
Rig: Option to switch-snap the IK pole parent (global space or local space)
Fbx export: The IK bones of the Unreal mannequin can now be exported as well (Unreal Engine only)
Fbx export: Added Root Motion export in option, to bake the "c_traj" animation controller to the armature animation ("root" node) (Unreal only, since Unity handles this automatically).
Skin: Skinning can now operate on low meshes versions, internally, to reduce the binding time of high-res meshes.
Smart: If the root marker is out of the mesh area, a warning message is sent.
Rig: The pinning value was not displayed in the usual "Rig Main Properties" tab
Rig: Mirroring shapes when the rig is not in the first layer was broken
Rig: Multiple neck bones and some facial bones were not in the layer 31
Rig: The new IK pole parent switch introduced an offset when snapping IK to FK
Fbx Export: Internally parent meshes to armature at export time to prevent issues, check for Multires modifiers that prevents shape keys export
