This Geometry Nodes system converts any curve into a customizable 3D chain. It includes over 20 distinct chain link variations, ranging from low-poly to stylized setups, complete with optimized materials. Users can manipulate parameters directly through the modifier interface, adjusting link spacing, global and individual scaling, orientation, offset, and random rotation. Supported by real-time previews, the setup is designed for building jewelry components, fashion accessories, and environmental props, functioning seamlessly within standing animation and simulation pipelines.
