Corrugated sheet metal

Generate tileable PBR maps of corrugated sheet metal with a sine or box rib profile, galvanized or painted, with screw rows, rust streaks running down from screws and patches, and dirt in the valleys. Use for sheds, barns, fences, shacks and industrial cladding.

Limits to consider

Corrugations run down the tile (vertical ribs); rotate the UVs for horizontal cladding. The profile is a height map, so the wavy silhouette at a sheet's edge needs geometry. Streaks always run toward the bottom of the tile. Occlusion is a blurred-height estimate, not ray traced.
