Sequin and paillette fabric

Generate tileable PBR maps of sequinned fabric: overlapping metallic discs in offset rows, each with its own tilt, a dished face and a centre hole, over the backing mesh, including holographic foil. Use for evening dresses, stage costumes, party props, bags and glam set dressing.

Limits to consider

Sequins are flat discs with a sloped and dished height, one layer per row in a fixed overlap order; there is no stitching thread across the face, no loose or flipped sequins and no reversible two-tone sequins. Sparkle comes from per-sequin normal tilt in the normal map, so it depends on the renderer's lights and reflections. Holographic colour is a hue wheel driven by tilt direction, a stylized stand-in for diffraction, and does not change with view angle. Occlusion is a blurred-height estimate, not ray traced.
