Auto-Rig Pro

What is Auto-Rig Pro?

Auto-Rig Pro is an all-in-one solution 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 many new features have been added since then.

Want to try first? Download Mike, free character rig here.

Rig features demo


Getting Started with Auto-Rig Pro:

Youtube Channel - Documentation - Frequently Asked Questions


Rig fast with the Smart feature



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.

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, 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 - Fully Feature

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 for advanced feathers rig:


Spline IK limb to rig ropes, tentacles, IK spine...


Advanced Spline IK


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...




Remap

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.

Video: Remapper demo

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:




Tell Me More!

  • 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
  • Shape keys drivers creation tool
  • Game engines support: Unity - Unreal Engine FBX Generic and Humanoid rig type

  • 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.
