Auto-Rig Pro

by Artell in Scripts and Addons


What is Auto-Rig Pro?


Auto-Rig Pro is an addon for Blender to rig characters, retarget animations, and provide Fbx/Gltf export, with presets for Unity, Unreal Engine, Godot. 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 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!

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...


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... The picker panel dynamically updates, so you can select any bone from the separate panel easily.




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. 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/GLTF format via a dedicated module, to proven engines such as Unity,Unreal Engine, Godot.

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 for UE4/UE5
  • 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


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:

ChildOf Constraints Switcher

Easily switch and snap from one ChildOf constraint to another with the automatic ChildOf switcher (universal tool, compatible with any rig)



Rig Layers

Store bones, armature layers, objects and collection in custom rig layers to easily manage the character features: hide or show clothes, hair, bones controller...


Built to Last

Blender is constantly improving and updating, and so is Auto-Rig Pro. But even though upgrades are nice, we don't want to miss the old rigs because of compatibility issues with newer versions. That's why backward-compatibility is always ensured at all costs, even if it involves a lot of maintenance on the code side. A legacy menu takes care of preserving features from the past. And if necessary, an "Update" button will upgrade the rigs automatically to the latest requirements, no loss!

--[3.68.24]--

New/improved:

  • Code structure: refactored code to clearly state licensing, "src" folder containing GPL python files, Royalty Free and CC0 for other asset blend files
  • Rig: New leg FK lock setting, similar to arms FK lock
  • Rig: When binding, removal of existing vertex groups can now be disabled as a default preference. A warning message is displayed at the first bind
  • Rig: New "Remove Selected Driver" function to remove the corrective driver of the selected shape key, deletes the helper bone as well
  • Rig: When initializing the armature scale during Match to Rig, the animations can now be scale compensated automatically. A dialog box prompts the user to enable scale compensation or not
  • Rig: Cosmetic, brought back some colorful icons from Blender 2.79!
  • Picker: Show a warning if the picker addon is not installed (Misc tab)
  • Skin: When binding, used vertex groups are now also searched in geometry nodes attributes, to exclude them from removal

  • Smart: Cosmetic, new markers icons, also fixing OpenGL error message on MacOS
  • Interface: the "Mirror Shape Keys" button was moved to the Shape Keys dropdown menu, and renamed "Mirror All Shape Keys"
  • Check for update: Now shows a differential log, comparing the log of the new available version versus the current old version

Fixed:

  • Rig: Spine reference bones had incorrectly more than one bbone segment, leading to error when keyframing the whole character
  • Rig: Add Blink Pose was not resetting bones transform properly after adding the constraint
  • Rig Layers: Made "Edit Layer..." a movable panel instead of an embedded menu panel to avoid the glitch making it disappear when moving the mouse cursor
  • Rig: IK-FK snap invalid vector angle error
  • Rig: The Lite version menu was kept hidden
  • Picker: Missing eyelids
  • Skin: Error while using edge selection mode with "Set Eyelids Borders"

  • Rig: Apply Pose as Rest Pose now support animation preservation, to ensure animations do not break when changing the rest pose. Can bake one keyframe per frame (best accuracy with interpolated motions) or only existing keyframes
