Cobblestone paving from Voronoi cells

In your harnessProcedural textureMIT

Generate tileable PBR maps of cobblestone or sett paving: domed, worn stones from Voronoi cells with soil, sand or moss in the joints. Use for streets, courtyards, castle floors and garden paths.

Limits. Stones are Voronoi cells, optionally trimmed toward discs, so they read as cut setts or rounded cobbles rather than scanned stones. Stones do not overlap and have no undercut. With jitter near 1 a few feature points fall close together and give narrow stones. Moss and soil are noise masks. Occlusion is a blurred-height estimate.
