Furrowed tree bark

Generate tileable PBR maps of tree bark with the trunk axis along the tile height: plates and furrows, interlaced ridges or stringy fibres, with cross-checks, lichen and moss. Use on tree trunks, logs and wooden props.

Limits to consider

Three stylized bark structures from noise and Voronoi cells; species are suggested by colour and proportion, not reproduced. The texture assumes a cylinder unwrapped along its axis, so it does not taper or bend around branches. Occlusion is a blurred-height estimate.
