Thatched roof of straw or water reed

In your harnessProcedural textureMIT

Generate tileable PBR maps of a thatched roof: overlapping courses of long straw laid down the slope or combed water reed showing its cut butts, with ragged course edges, weathering to grey and moss in the shelter of the courses. Use for cottage roofs, huts, barns and fantasy villages.

Limits. Courses are straight horizontal bands of painted strokes; ridges, eaves, gables and decorative ridge patterns are out of scope. The slope runs down the tile (ridge at the top), so map V along the roof slope. Strands are straight capsules with a z-buffer, not bent fibres, and the moss is a tint with a slight lift, not modelled growth. Strand counts are fixed per course, so very thin strands at small sizes are drawn at least about a pixel wide. Occlusion is a blurred-height estimate.

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
Course bands with whole counts down the tile, Z-buffered capsule painting of strands with wrap-around, Height rising from the hidden top of a course to its exposed edge, Ragged course edges from random strand lengths, Noise-driven weathering and sheltered moss masks, Height to tangent-space normal by central differences, Cavity occlusion from blurred height
