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.
If the character is humanoid, 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.
The rig system itself is 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.
If you encounter any bugs please report it, be assured you'll receive support/bugfix quickly. Updates are free and will remain free! Also make sure to read the FAQ and the documentation to solve recurrent issues.
Modular
Customize the rig definition in a few clicks: fingers, toes amount, spine and neck bones amount, tail, breasts, ears, duplicate or remove limbs to rig spiders, centaurs, or whatever!
Video tutorial, rig a centaur with the multi-limb feature: Centaur Rig
The picker panel dynamically updates: select any bone from the separate panel easily.
Intuitive tool to edit the bone shapes, with automatic mirror.
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. 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.
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:

Extensive list of what's in the box:
Automatic bone placement solver based on mesh recognition for bipeds character

Complete set of secondary controllers for fine pose sculpt
Advanced facial setup with automated placement
Shape keys drivers creation tool
Game engines support: Unity - Unreal Engine FBX Generic and Humanoid rig type
Bone remapper to retarget any armature action to another one, with different bone names and bone orientations. Bvh/Fbx files compliant - Mixamo animations, with IK support
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.
Updates:
Make sure to uninstall the current addon before installing the new one and restart blender
--[3.47.15]--
New/improved:
Rig:
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
Skin:
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.
Smart:
Added 3 fingers detection
Remap:
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
Fix:
Apparently identical class names could cause installation error in some cases, the classes have been renamed to avoid it.
Export
Armature object scale was not properly supported
Smart
Issue with objects containing shape keys
The eyelids bones roll could be wrong
----[3.46.17]----
New/improved:
Rig:
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
Fix:
Rig:
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 tool had issues with x-mirror
Smart:
Issue with keyframed objects
Issue with objects containing shape keys
The eyelids bones roll could be wrong
Export:
The subsurf modifier was not disabled properly when shape keys are used
----[3.45.12]----
New/improved:
Rig:
New Bird preset armature
New IK foot offset controller in option
New "Reset" button in the Rig Tools menu to reset all controllers to rest position (similar to the picker's reset button)
New Set T-Pose feature along the previous A-Pose
Export:
Custom bones: so far, custom bones had to be defined with a "cc_" prefix in their name. They can now also be defined by adding a custom property to the bone named "custom_bone" or "cc", which allows to lift this naming restriction.
Added the Check Rig tools buttons to the N key panel
Check rig tools: now also checks for invalid armature modifiers
Fix:
Export:
Missing icon in Blender 2.80 used in Blender 2.81, preventing the Fbx export UI to show
----[1.0]----
