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!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.

[3.75.20]

New/improved:
Smart: AI: Guess Fingers support for 4 fingers
Smart: When fingers are disabled, the hand bone tail is now snapped to the hand_tip marker position
Smart: New Elbow marker to improve accuracy of the elbow recognition
Smart: AI: Elbow marker implemented in the AI models
Smart: UI: A large hand icon is displayed, showing how many fingers should be recognized
Smart: AI: Optimized fingers AI processing, from 1.5x speedup to more depending on the CPU.
Smart: AI 1.14: Enhanced AI models. Support for curled fingers has been improved.
Smart: The neck height has been refined, it does not rely on the full body height anymore. It was not accurate with certain character designs (hat, bulky hair…)
Smart: New helper images to place the body markers
Smart: New helper images for optional markers
Rig: New Muzzle controller (Limb Options), to offset the whole mouth plus nose optionally
Rig: New “Set Custom Shape” function, to add a custom shape to a bone using the existing shape library (shapes located in Auto-Ruig Pro’s lib + current file). The custom shape scale can be set here too.
Rig: Init Scale: Do not require actions scaling if the rig is fresh new
Skin: The feature that auto-updates arms and legs twist weights when changing Secondary Controllers, now supports the switch from/to Bendy-Bones secondaries. Multiple twist vertex groups are generated or merged together on the fly. Uses same functions as the Smooth Twist Weights feature.
Export: Unity: Convert Armature Axes is now enabled automatically when switching to Unity engine, to zero out the skeleton rotation
Export: Add Dummy Mesh is enabled by default for Unity, otherwise Unity won’t import the root node when the file contains only animations
Export: Do not export non-deforming kilt bones

Fixed:
Smart: AI: Support for ACES color profile
Smart: Fix phalanges with incorrect roll
Rig: Apply Pose as Rest Pose: Error when Kilt limbs had more than one subdivision, while reference bones were not subdivided
Rig: jawbone_track bone not parented to c_skull_01
Rig: Tagged feather bones with a custom prop, was missing for Dupli Limb
Rig: Error handling when transferring vertex group with invalid ID
Rig: Error in leg_update_vgroups(), missing thigh_ref variable
Skin: Error introduced in previous release, leading to missing vertex groups when binding (e.g heel vertices not bound)
Version: Compatibility issue when assigning actions on old files, missing slots
Remap: Ensure fingers are switched to FK, since IK is not supported
Remap: Clean FK Rotation was broken due to latest changes with multi selection mode
Export: Children objects that were hidden were still exported, while the root hidden object is not
