Blender Auto-Rig Pro 3.75.11 is a powerful and versatile character rigging addon tailored for animators, game developers, and 3D artists working within Blender. Originally built as an internal rigging solution, it has evolved into a full-featured tool thanks to strong community input and continuous development. It is especially well-suited for preparing characters for use in real-time game engines like Unity, Unreal Engine, and Godot.







One of its standout features is the Smart Rigging system, which drastically reduces rigging time by automatically detecting and placing bones for both humanoid and custom characters. Auto-Rig Pro also offers extensive customization, allowing users to adapt the rig for different body types, including bipeds, quadrupeds, and stylized figures.

This addon supports modular rig definitions, giving artists full control over rig complexity, including facial setups, fingers, and secondary deformation controllers. The tool also excels in animation retargeting, enabling easy remapping of motion data between different character rigs—ideal for reusing animations across multiple assets.

Game engine compatibility is a key focus. Auto-Rig Pro includes FBX and GLTF export tools, ensuring clean and optimized exports for Unity, Unreal Engine, and Godot. Advanced features like IK-FK snapping, hybrid IK pole vectors, auto-eyelid rotation, and secondary control layers allow for detailed and expressive character animations.

The addon enhances skinning workflows with improved methods for weight painting and mesh binding, leading to better deformation and more natural animation. Artists can sculpt expressive poses and facial movements with precision thanks to advanced facial rigging options.

Whether you're developing cinematic animations or real-time game characters, Auto-Rig Pro 3.75.11 provides the tools needed for fast, flexible, and professional-quality rigging directly within Blender.
