What is Auto-Rig Pro?

Auto-Rig Pro is an addon for Blender to rig characters, retarget animations, and provide Fbx/Gltf export, with settings 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 information.

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 anything that makes more or less sense.

Advanced, customizable facial:

Wings limb for advanced feathers rig: 

Kilt limb to rig kilt, dresses, skirt-like clothes

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

3 bones IK for quadrupedal, digitigrade creatures:

Fingers and Toes 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

Skeleton export to FBX/GLTF format.  Complies with Unity, Unreal Engine, Godot...

Export Types:
Universal to export the skeleton of any creatures
Humanoid for bipeds only, with options for easy retargetting and root motion in game engines

• 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:

Joints Fans are helper bones in option, allowing correct volume preservation in tricky areas such as elbow, wrist, thigh, knee, even if "Preserve Volume" skinning (Dual Quaternions) is disabled.

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!

--[3.73.29]--

New/improved:

• Compatibility: Blender 4.3: FBX export
  
• Export: New "Actions Linker" menu, to link an action to another one. Useful if exporting RigA animation, that depends on RigB through constraints (such as two characters holding each other's hands).\nIf animations are interdependent, it is necessary to declare these links for correct animation export.
• Export: New "One File per Actions List" setting, when enabling both "As Multiple Files" and "Actions Manager". This allows to export one file per Action List, including all actions in the list.
• Export: Godot: New setting to comply with Godot Root Motion axes
• Export Godot: Removed the "Root Motion" setting that bakes the c_traj animation to armature object, not relevant for Godot Root Motion.
• Export: Actions Lists: Filtered actions in the actions selector, so that actions that are already part of the current list are removed from the search list
• Export: GLTF: Exposed the "Start from frame 0" setting, in order to force the first frame of each action to be zero if enabled
• Export: UE: Removed the extra orientation tweaks applied to the spine bones when exporting with Mannequin axes. It was offsetting the angles by a few degrees to improve the match in case of straight spine bones, but can be misleading. It is best to align the spine bones manually. It can still be enabled in the "Legacy" menu though.
• Export: Actions Manager: New "Batch" feature to add multiple actions at once to a list, with filtering
• Export: UI: Added the "Rename Bones from File" checkbox in the properties panel too. Was confusing to have it only in the menu located in file export browser
• Export: Avoid operator when removing shape keys for faster performances
  
• Rig: Spline IK: Changed "Parent External Bone to" setting, was limited to the tip bone before. Now applies to all bones of the chain, and to Deforming or Twist bones instead of controllers. Can still be parented to controllers if necessary, by directly parenting Spline reference bones to them.
• Rig: Spline IK: New "Add Tail Bone" option. This adds an extra bone at the tip of the chain, that is not part of the main IK chain. Useful when needing to parent other limb to the tip, that must not be stretched or rotated with the main chain, such as rigging a spine for quadrupeds.
• Rig: Spline IK: New "Preserve Shape" option, to preserve the current shape when changing the amount of the spline bones.
• Rig: Spine: New "Preserve Shape" option, to preserve the current spine shape when changing the amount of bones
• Rig: Leg: New Limb Option to skip the foot IK offset alignment when Match to Rig, allowing custom positioning
• Rig: Spine: New "Parent Fallback" parameter in Limb Options, to set the default spine parent in case the root reference bone is not parented. By default parented to "c_traj". No parent if set to None.
• Rig: Tail: New "Preserve Shape" option, to preserve the current shape when changing the amount of the tail bones
• Rig: Spine, Tail, Spline IK: Removed "Update Transform" option, was confusing. Now, automatically update the bones transforms if the count was changed, using grid align or preserve shape if enabled.
  
• Picker: The picker camera is now set automatically when clicking "Add Picker"
• Picker: Support reverse spine bones
• Rig Tools: New "Extract Root Motion" function that tracks and bakes the "c_traj" controller to the pelvis position, while maintaining it on the floor, and preserving the rig animation
• Rig Tools: Extract Root Motion now supports Location Z with initial offset applied
• Rig Tools: Improved Extract Root Motion performances, around 4x faster (before: 24 sec for 400 frames, after: 6 sec)
• Rig Tools: Extract Root Motion: Added X and Y offsets
  
• Remap: Added "Extract Root Motion" as an option when retargetting
• Smart: Facial features are now togglable: Eyebrows, Eyes, Ears, Nose, Lips, Tongue, Teeth, Chin
• Smart: Auto filter mesh objects when clicking "Get Selected Objects". This avoids throwing an error if non-mesh objects are selected.
• Smart: UI: Moved the "Fingers" checkbox in the header of the Fingers tab to minimize redundancy
  

Fixed:

• Rig: The horse rig was containing unwanted actions data leftovers
• Rig: Removed the "body_mid" collections coming from old armature presets
• Rig: Facial: Error when disabling the mouth bones
• Rig: Bottom bones had accidentally their Deform property turned off
• Rig: Apply Pose as Rest Pose crashing in case of numerous shape keys
  
• Export: Skinned objects having same name as export skeleton were clashing. It now throws a warning before exporting.
• Export: Add batch actions to Action Manager could generate an error if an action was removed from file
• Export: GLTF: Disabled the "export_apply" argument from the actual export, was preventing shape keys to export. Modifiers are pre-applied by AutoRigPro functions anyway, so no changes on the user side.
• Export: Error when exporting actions list containing removed actions
• Export: The exported skeleton was incorrectly named with an "_arpbob" suffix when the rig export name was the same as the armature name
• Export: Apply Shape Keys was failing if the basis shape key was not named "Basis". Now, always refer to the shape key at index 0 as Basis
• Export: Humanoid: Invalid fingers export when exporting more than 2 arms
• Export: Shape keys could not apply and export correctly under certain circumstances, was missing "from_mix" set to false
  
• Rig Tools: Extract Root Motion quat_prev error
