Breeze block screen wall with see-through openings

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 to consider

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.
