GN Rigging System

High-Quality Character Deformation Powered by Geometry Nodes

GN Rigging System is a fully procedural rigging solution built entirely with Blender Geometry Nodes. It provides an Armature-like workflow while offering advanced skinning algorithms for higher-quality character deformation.

Designed for technical artists, procedural workflows, and character animation pipelines.

Features

Armature-Style Workflow

• Familiar bone-driven deformation
• Multi-bone weighted skinning
• Real-time Geometry Nodes evaluation
• Easy integration into existing animation workflows

Enjoy the flexibility of Geometry Nodes without sacrificing the traditional rigging experience.

Linear Blend Skinning (LBS)

The system includes a complete implementation of Linear Blend Skinning, providing:

• Fast and stable deformation
• Multiple bone influence support
• Industry-standard skinning behavior
• Excellent compatibility with common rigging workflows

Dual Quaternion Skinning (DQS)

Built-in Dual Quaternion Skinning delivers smoother and more natural deformations by preserving volume during rotations.

Benefits include:

• Reduced candy-wrapper artifacts
• Better twisting behavior
• Improved joint deformation
• More organic character motion

DQS Compensation

An additional post-processing compensation stage enhances standard DQS deformation by minimizing volume expansion and preserving local shape details.

This produces cleaner results in complex joint areas and improves overall deformation quality.

Optimized Centers of Rotation (OCoR)

The system supports Optimized Centers of Rotation (OCoR), allowing each vertex to rotate around an optimized center instead of a simple weighted average.

This significantly improves:

• Shoulder deformation
• Elbow bending
• Knee articulation
• Complex multi-bone regions

for more realistic and visually pleasing animation.

Delta Mush

Integrated Delta Mush smoothing provides a final deformation pass that:

• Smooths skinning artifacts
• Preserves the overall silhouette
• Reduces sharp creases
• Produces cleaner and more natural surface deformation

without requiring additional manual weight adjustments.
