Dry stone wall of stacked irregular slabs

In your harnessProcedural textureMIT

Generate tileable PBR maps of a dry stone wall: irregular, tapered flat stones stacked in rough courses without mortar, deep dark voids, small chinking stones wedged into the joints, lichen patches and moss. Use for field walls, terraces, ruins and rural buildings.

Limits. Stones are rotated, tapered rounded rectangles with noisy outlines in rough courses; there are no through stones, coping, batter or stones that cross courses. Voids are drawn as flat dark recesses, and chinks are small ellipses. Lichen and moss are noise patches, not grown. Occlusion is a blurred-height estimate, not ray traced; deep voids read best with the height map for parallax or displacement.
