This is the documentation for the Procedural Cloth Sewing Toolbox asset pack for Blender 4.2+. The asset pack allows to add fully procedural and intricate sewing details to any mesh, regardless of its deformation, animation or simulation, in a way that is really stable thanks to UV space computing. You can now effortlessly add stitches, hems, bondings, complete seams, buttons, patches or other object, as well as animate everything and use custom attribute for precise procedural shading work, and this even after your garment has been designed and simulated. All tools provided in the pack are documented here with precise description of behavior, as well as input and outputs attributes of each tool.
