Zellige eight-point star and cross tiles

In your harnessProcedural textureMIT

Generate tileable PBR maps of the eight-point star and cross tessellation in handmade zellige: stars and pointed crosses with grout, steep chipped cut edges, uneven glossy glaze with pinholes and per-piece colour. Use for Moroccan and Andalusian walls, fountains, floors and backsplashes.

Limits. One layout only: stars sized to meet tip to tip, so the crosses have pointed arms; other star proportions and larger girih patterns are out of scope. Glaze thickness, pinholes and chips are noise-driven approximations; the glaze is opaque colour with no depth or crazing. Colours are artistic. Occlusion is a blurred-height estimate, not ray traced.
