Quick start

1. Open GN_Rigging_V3.blend, or append the node groups into your own file (they are marked as assets, so you can also drag them from the Asset Browser).
2. Build a skeleton: Skeleton from Armature (pick your armature and the skinned mesh) or Skeleton from Edges (any edge mesh becomes bones).
3. Get weights: use the weights your armature already has, or run Bone Capture on the mesh for automatic line or capsule weights. Compress Bone Weights keeps the strongest influences for speed.
4. Deform: connect the rest skin and the posed skeleton to Bone Deform and choose the Skinning Method.
5. Optional: add DQS Compensation after DQS, or run Compute CoR once on the rest skin (cache it in a Bake node) before using Optimized CoR.

Which skinning method?

• LBS: fastest, but elbows collapse and twists pinch.
• DQS: keeps volume, may bulge on the inside of a bend.
• DQS + DQS Compensation: removes the bulge.
• Optimized CoR: best joint shape for characters.
• Delta Mush: smooths artefacts while keeping surface detail.

Debugging

Visualize Rig draws bones or axes, Visualize Bone Weight colours the influence of one joint, Detect Error helps you find problems in a rig.

Requires Blender 5.2 or newer.
