This setup uses Geometry Nodes to generate fully customizable chains along drawn curves. Users can draw curve paths freely or attach them directly to surfaces, making it useful for creating both environmental chains and surface-conforming accessories like bracelets.

The node group includes real-time controls for adjusting chain properties, including radius, tilt, width, bevel, roundness, and rotation. It relies on geometry instancing to maintain fast viewport performance while making adjustments. The generator comes with a default chain material applied, and UV coordinates are automatically generated and stored as attributes for custom mapping.
