Breeze block screen wall with see-through openings

In your harnessProcedural textureMIT

Generate tileable PBR maps with alpha of a breeze block screen wall: stacked concrete or clay blocks with mortar joints and cut-out openings (circles, quatrefoils, diamonds, flowers or a grille), darkened inner walls and weathering. Use for mid-century facades, garden screens and balconies.

Limits. The openings are alpha cut-outs on a flat card: the block depth is only suggested by darkening near the openings and the height map, so the see-through view does not shift with the viewing angle as real block walls do. Blocks are stacked in a square grid; running bond and half blocks are out of scope. Motifs are fixed signed-distance shapes, not catalogue designs. 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
Signed distance unions and intersections of circles, ellipses, boxes and half-planes for opening motifs, Alpha from the opening distance, anti-aliased over one pixel, Stack-bond square grid with mortar joint distance, Per-block hashing for colour and tone, Fractional Brownian motion for stains and streaks, Height to tangent-space normal by central differences
