Procedural Topstitch Generator is a Geometry Nodes setup that automatically creates 3D stitching along curves, text objects, and imported logos. The tool provides a non-destructive alternative to traditional array and curve modifier stacks, updating geometry in real time as the underlying curves are edited.

The node group exposes several parameters in the modifier panel to customize the look of the stitches. Users can adjust stitch size, spacing, surface height offset, global scale, and random variation to achieve specific styles. Inputs for material customization are also included. It is designed for detailing 3D garments, footwear, bags, and close-up product visualizations.
