Auto-Rig Pro v3.73.10 (FULL)

Auto-Rig Pro is a Blender add-on designed to automate character rigging, animation retargeting, and export to game engines. The add-on features an AI-powered Smart tool that automatically positions bones for humanoid characters, while still allowing manual refinement for non-humanoid creatures like horses or dogs. The workflow is non-destructive, meaning rigs remain fully editable at any stage.

The add-on supports extensive customization, including fingers, wings, tails, facial rigs, and multiple spine or neck bones. You can duplicate or remove limbs to rig creatures with unconventional proportions, such as spiders or centaurs. Secondary controllers placed along limbs enable fine pose sculpting and cartoon effects, with three deformation modes: Twist, Additive, and Bendy-Bones.

Auto-Rig Pro excels at retargeting animations between different armatures through its Remap feature, which matches bone names and orientations and works with imported BVH and FBX files. The add-on exports skeletons in FBX and GLTF formats with dedicated support for Unity, Unreal Engine, and Godot, including specialized settings like twist bones for volume preservation and unit conversion to match engine scale requirements.

The package includes improved auto-skinning based on Blender’s heatmap algorithm, IK-FK snapping, a bone picker, corrective shape keys, and compatibility with related tools like the X-Muscle System and Voxel Heat Diffuse Skinning addon.
