Bamboo poles and split slats

In your harnessProcedural textureMIT

Generate tileable PBR maps of bamboo: culms side by side with nodes at uneven heights, node ridges, sheath scars and waxy bands, fibre streaks and spotted mottles, or split slats as in a blind or mat. Use for fences, screens, furniture, wall cladding, rafts and tropical scenes.

Limits. Culms are straight cylinders in a height field running down the tile, all lying in one plane; there is no taper, bend, branch, leaf, cut end or lashing. Node positions are jittered per pole, and pole widths vary but always fill the tile width exactly. The cylindrical shading is partly in the albedo as well as in the normal map. Occlusion is a blurred-height estimate, not ray traced. Colours are artistic.
