Staggered roof shingles: slate, asphalt or cedar

In your harnessProcedural textureMIT

Generate tileable PBR maps of roof shingles in staggered overlapping rows: natural slate, asphalt with mineral granules or split cedar shakes, with square, round fish-scale or pointed butts, keyways, cast shadows under each butt, and weathering. Use for house roofs, towers, sheds and shingled walls.

Limits. The slope always runs down the tile height. Shingles are flat pieces whose thickness shows only as a step in height and a darker band; there are no nail heads, ridges, valleys, flashing or architectural laminated shingles. Shadows under the butts are tinted into the albedo, so they read as baked under strong side light. Granules, cleft layers, grain, lichen and moss are noise approximations. Occlusion is a blurred-height estimate, not ray traced.

Checks
command line generates declared maps, maps decode, maps have declared size and channels, maps tile without a seam, normal vectors unit length facing out, maps carry detail, godot imports the maps, godot material template loads every map, godot compatibility render, capture shows the textured surface, blender builds the material
Techniques
Overlap order of rows laid from the eaves upward, First covering row from the butt line below, with shaped butts and keyways, Round and pointed butt profiles as lifts of the butt line, Rows of equal or log-normal random widths with alternating or random offsets, Fractional Brownian motion stretched across or along the slope for cleft and grain, Height to tangent-space normal by central differences
