Auto-Rig Pro 3.78.50 for Blender Full Version Free Download

Character rigging is one of the most technically demanding parts of a Blender animation workflow. Building bones, configuring IK and FK controls, creating facial rigs, setting up skinning, and preparing characters for game engines can take a considerable amount of time. Auto-Rig Pro 3.78.50 is designed to streamline that entire process, giving Blender artists a comprehensive system for rigging, posing, animation retargeting, and exporting characters.

Created by Artell, Auto-Rig Pro combines automatic rig generation with an extensive set of manual controls. It supports standard humanoid characters as well as creatures with additional limbs, tails, wings, tentacles, and other specialised structures.

What Is Auto-Rig Pro for Blender?

Auto-Rig Pro is a Blender add-on focused on character rigging, animation retargeting, and game-engine export. Its Smart feature can automatically position bones for humanoid characters using mesh recognition, while the resulting rig remains editable so artists can refine the placement when necessary.

The system is based on a non-destructive workflow, allowing the rig definition and reference bones to be modified without starting the entire process again.

Smart Automatic Rigging

The Smart feature is one of Auto-Rig Pro’s biggest time-saving components. For humanoid characters, it can analyse the model and automatically position the reference bones.

Artists can then adjust those bones manually before generating the final control rig. This is useful because automatic rigging rarely gets every proportion perfect, particularly with stylised characters or unusual anatomy.

The add-on also supports rigging non-humanoid creatures without the Smart system, making the workflow suitable for animals and other character designs.

A Modular Character Rig

Auto-Rig Pro is highly modular, allowing artists to customise the rig according to the character. Fingers, toes, ears, tails, wings, additional spine or neck bones, and other limbs can be added or removed as needed.

This is particularly useful for fantasy and creature characters. Multiple limbs can be duplicated to create rigs for spiders, centaurs, or other unusual designs, while specialised systems such as Spline IK can be used for ropes, tentacles, and flexible spine structures.

There are also dedicated limb options for wings, skirts and kilt-like clothing, giving the rig system considerably more flexibility than a simple humanoid template.

Advanced Facial Rigging

Auto-Rig Pro includes an advanced facial setup with automated placement tools. Facial controllers can be incorporated into the character rig alongside standard body controls, while tools for shape-key drivers help connect facial deformation systems to the rig.

Eye controls include IK/FK functionality, and automatic eyelid rotation can help simplify common facial animation tasks.

This makes Auto-Rig Pro useful for characters that require more than basic body movement, particularly for dialogue, close-up animation, and expressive performance.

Secondary Controllers for Better Posing

The add-on includes Secondary Controllers positioned along the limbs for more detailed pose sculpting. These controls can be used for bending, stretching, twisting, and cartoon-style deformation.

Rather than relying entirely on corrective shape keys, animators can use these secondary controls to refine the silhouette and volume of a pose. This can be especially useful for stylised animation where exaggerated body shapes are part of the artistic style.

Auto-Rig Pro also includes tools for creating corrective shape keys for IK-FK chains and Joint Fans that help preserve volume around difficult areas such as elbows, knees, wrists, and thighs.

IK-FK and Animation Controls

Auto-Rig Pro provides extensive IK-FK functionality for animators. Controllers can be snapped between IK and FK modes, while options such as foot roll, knee and elbow pinning, automatic controller hiding, and hybrid IK pole controls make posing more intuitive.

The system also supports multiple Child Of constraints for hands and feet. This allows a character’s hands or feet to switch between different parent spaces, which can be valuable in situations such as holding a steering wheel and then interacting with another object.

Remap and Animation Retargeting

The Remap system allows animation actions to be transferred from one armature to another, even when the rigs have different bone names or orientations.

It supports Auto-Rig Pro, Rigify, custom rigs, and imported BVH or FBX armatures. IK support for hands and feet helps improve the accuracy of the resulting motion, while an interactive offset tool can compensate for differences in character proportions.

This makes Auto-Rig Pro useful when working with existing animation libraries or bringing motion-capture and third-party animation into a Blender character pipeline.

Export to Unity, Unreal Engine and Godot

Auto-Rig Pro includes dedicated tools for exporting characters to FBX and GLTF for game engines. The export system supports Unity, Unreal Engine, and Godot, with options for humanoid and universal skeletons.

Features include root motion, multiple twist bones for better volume preservation, automatic A-pose conversion, Unreal Mannequin compatibility, selective action export, and support for shape keys or blend shapes.

These tools can reduce the amount of technical preparation required when moving Blender characters into real-time applications.

Rig Layers and Customisation

Auto-Rig Pro also provides a customisable rig interface. The UI layout, button positions, colours, and background imagery can be changed, while the bone picker provides another convenient way to select controllers.

Custom rig layers make it easier to organise complicated characters by hiding or showing clothing, hair, controllers, bones, and other components as needed.

The developer also emphasises backward compatibility, with legacy features maintained and an update system available for bringing older rigs up to current requirements.

Auto-Rig Pro 3.78.50

The requested version is Auto-Rig Pro 3.78.50. The current Superhive listing identifies the product as an actively maintained Blender add-on, with support extending through newer Blender releases.

The marketplace currently lists Auto-Rig Pro for Blender 2.93 through 5.2. The full package is listed at $50, while a Lite version containing the core Auto-Rig Pro system is available separately.

Who Should Use Auto-Rig Pro?

Auto-Rig Pro is suited to character animators, riggers, game developers, VFX artists, indie filmmakers, and Blender users who regularly need production-ready character rigs.

It is particularly valuable for artists who need to move characters between Blender and game engines or who frequently retarget existing animations to custom characters.

Final Thoughts

Auto-Rig Pro 3.78.50 is a comprehensive character-rigging solution that goes well beyond automatic bone placement. Its modular rig construction, facial controls, IK-FK systems, secondary controllers, animation retargeting, corrective deformation tools, and game-engine export capabilities make it suitable for both straightforward humanoid characters and much more complicated creatures.

For Blender artists who want to spend less time building technical rigging systems and more time animating, Auto-Rig Pro provides a highly customisable workflow from initial skeleton setup through final animation and export.
