Keeled snake scales with body patterns

In your harnessProcedural textureMIT

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.

Render of Keeled snake scales with body patterns

Limits. 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.

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
Rhombic lattice of offset rows with whole counts on the torus, Superellipse scale outline with exponent near 1 for pointed tips, Local overlap order: the row above covers the row below, Keel ridge along the scale axis, Pattern fields sampled once per scale centre, Height to tangent-space normal by central differences, Cavity occlusion from blurred height
