Auto-Rig Pro v3.74.62 | FULL (now AI powered)

Auto-Rig Pro is a Blender add-on designed to automate character rigging, animation retargeting, and export workflows for game engines including Unity, Unreal Engine, and Godot. The add-on features an AI-powered Smart tool that automatically positions bones for humanoid characters based on mesh recognition, while remaining fully editable for refinement. It supports non-humanoid creatures such as quadrupeds, and allows customization of limb configurations including fingers, wings, tails, and multiple spine or neck bones.

The add-on includes a comprehensive retargeting system that remaps animations from any armature to another, supporting different bone names and orientations—including imported BVH and FBX files from sources like Mixamo. It offers multiple deformation modes (Twist, Additive, and Bendy-Bones), secondary controllers for fine pose sculpting, and advanced facial rigging capabilities. Export functionality supports FBX and GLTF formats with specialized settings for each engine, including unit conversion, twist bones for volume preservation, and Unreal Mannequin bone hierarchy support.

The workflow is non-destructive, allowing you to edit reference bones and adjust the rest pose at any time without starting over. Advanced skinning uses heat-map based methods with automatic element splitting and voxelization. Additional features include IK-FK snapping, corrective shape key generation, joint fans for volume preservation, and compatibility with external systems like the Voxel Heat Diffuse Skinning addon and X-Muscle System.
