Painted metal with chips and scratches

Generate tileable PBR maps of painted steel worn through in layers: top coat, primer and bare metal at stepped chip edges, scratches cut to the metal, rust and grime, with a metallic map for the exposed steel. Use for machinery, vehicles, containers and railings.

Limits to consider

Chips and scratches are placed by noise and random strokes, not by where a real object wears (edges, handles, contact points); combine the maps with an edge-wear mask from your tool for that. Scratches carry no burr or directional sheen. Rust is a colour and roughness layer without its own relief. Occlusion is a blurred-height estimate, not ray traced.
