What is Quick Rig?
IMPORTANT: Quick Rig is an extension for the Auto-Rig Pro addon, it means Auto-Rig Pro must be purchased and installed first.

Don’t waste your time re-rigging already rigged characters anymore!

Quick Rig turns rapidly any skeleton + mesh into a full Auto-Rig Pro armature with controllers ready for animation, including weights preservation, IK-FK generation, animation support.

Built to support the vast majority of character skeletons, even non-standard bones axes.

How it works:
See the video demo.

Add limbs: select the first bone of a limb (e.g. the shoulder for the arm), then click the + button to add a limb
Ensure the limbs settings are correct: blanks are filled with correct bones, and bones axes are properly set. These settings are automatically set when adding the limb, but depending on the skeleton complexity they may be incorrect sometimes.
Choose Preserve or Convert mode. Preserve keeps the existing armature untouched while binding it to the rig controllers only, while Convert will generate a full Auto-Rig Pro armature compliant with all Auto-Rig Pro editing and exporting tools
Click Quick Rig! to generate the final rig
To try other settings, click Revert to go back to the base skeleton

Features:
Preserve and Convert mode, to preserve the base skeleton as it is or convert it to a complete Auto-Rig Pro armature for more advanced editing tools.
Constraints retargetting (some limitations apply)
Shape keys drivers retargetting

Auto-detection of the selected bone type for quick limb setup
Animation support, the skeleton animation is baked to the control rig in option
Import and export custom mapping preset files
Built-in mapping presets: Realillusion Character Creator, DAZ, Human Generator, Mixamo, Unreal Mannequin, VRoid…

Supports the following limbs:

Spine: from 2 to 6 spine bones
Head: neck (optional), head bone. Up to 10 neck bones.
Leg: thigh, calf, foot, toes bone. With optional twist bones and “3 bones leg” settings for extra thigh bones, for quadrupedal creatures
Arm: shoulder (optional), arm, forearm, hand and finger bones (optional). With optional twist bones. 3 or 4 phalanges per finger (with or without metacarps).

Orphan bones support: even bones that are not part of the standard limbs definition (facial bones, unusual twist and tweak bones, bones for clothes and props…) are inserted in the rig hierarchy automatically, to ensure *all* bones are included in the final rig properly.
Custom shape drawing options for orphan bones.
Automatic leg and arm angle correction if bones are perfectly straight, to avoid IK direction issues
Neck with optional automatic twist rotation
Weight Overrides: If the skeleton is special, use weight overrides to ensure to set correct skinning weight matches, by manually setting the correct bone weight for a given bone.

Limitations:
Although the tool is quite complete, some limitations apply that may be lifted in future versions:

Multiple heads or multiple spines not yet supported
Facial head bones not yet supported as Auto-Rig Pro facial bones, however they’re supported as default controllers for now

Updates:

–[1.26.46]–

New/Improved:

Version: Addon as Extension for Blender 4.2
New “Parent to Main Bones” setting for orphan bones, to parent them to main bones instead of other orphan bones when possible. Helps to resolve cases of complex skeletons, where orphan bones lose their parents
“Parent to Main Bones” is now disabled by default
Added “Auto IK Roll” setting for arms and legs, disabled by default
Each fingers phalange can now be manually set, useful in case phalanges are not direct child of each other
Improved Arm and Fingers Up Axis autodetection by evaluating the axes in a virtual T-pose
Added “Up Axis” setting for arm bones (was only for hand and fingers before)
Improved the straight arms/legs correction (to comply with IK constraints), the angle is now evaluated in the bone’s Z axis space instead of global space
Check for update: Now shows a differential log, comparing the log of the new available version versus the current old version
New UE5 preset
Multiple animations baking support
The c_root_master controller shape now tries to fit the global character scale better
Changed the default presets path from C:/Quick Rig Presets/ to /Quick Rig Presets/ to be OS agnostic
Added Global or Local space retargetting for orphan bones animated locations (was always Local before)
Blender 4.0 support. Backward-compatible with older versions.
Interface: moved the “Enable Weights Override” checkbox near the bone names entries for arms and spine limbs
New “UE5 Manny (2 twists)” preset, works best when exporting back the rig to UE
New “Foot Dir Axis” setting for Leg limbs, to determine the foot axis direction in case no toe bone is set
Added a “Fuzzy Match” optional setting when importing built-in presets. It attempts to match the bone names from the preset that are different from the actual skeleton. Warning, prone to error.
New “Force Pelvis Up” setting for spine limbs. Useful when the pelvis bone is not straight up, typically for humanoid characters. Updated the built-in presets with this setting too.
Replaced the “Layer” setting with “Collection” for Blender 4+ versions
New Genesis 9 preset, renamed other presets more appropriately
New UE MetaHuman preset
The Quick Rig preset directory is now set in the Documents folder by default
Toes are now supported for Leg limbs
New “Mirror” feature to automatically create a mirrored limb (only works if bone names are ending with ‘_l’, ‘.l’, ‘_left’ and similar), or replace existing mirrored limb
New “Up” and “Down” buttons to sort the limbs list manually
New Tail limbs support
Improved the “Mirror” feature, supports a wider syntax for left and right identifier, and sort the mirror limb after the original one in the list

Fixed:

Error when versioning the files, leading to missing code patches in 1.26.32-33
Disabled “Freeze Armature”, not necessary anymore in latest versions and could lead to issues
Compatibility with Blender 4.1+, import presets from file
Display an explicit error when trying to enable animation baking while Auto-Rig Pro Light version is installed
Compatibility with Auto-Rig Pro 3.68.21+
Compatibility with Auto-Rig Pro 3.68.67+ when remapping animation
Error handling, warning message if twist bones inputs are missing
Orphan bones not parented correctly when Manual Phalanges were enabled
Compatibility with Blender 4.0 alpha
Version checker updated, Auto-Rig Pro should be at least to 3.66.25 version to work properly with Quick Rig
Check for update: missing functions
Backward-compatibility issue related to meshes data when reverting rigs to skeleton
Debug mode was enabled
Overrides for Arm limbs were throwing an error when manual phalanges were enabled
Error with missing toes
Check for Update broken in Blender 4.2+
