Keeled snake scales with body patterns

Generate tileable PBR maps of snake skin: overlapping keeled scales on a rhombic lattice with python blotches, coral bands, dorsal diamonds or a plain speckled skin, coloured scale by scale. Use for snakes, lizards, dragons, reptile-leather goods and creature props.

Limits to consider

Scales are rounded-diamond height fields of one size in regular offset rows; belly scutes, head plates and the change of scale size around the body are out of scope. The body axis runs along V with the head toward the top. Patterns are stylized fields sampled at scale centres, not the markings of real species, and there is no iridescence or shedding skin. Occlusion is a blurred-height estimate, not ray traced. Colours are artistic.
