Furrowed tree bark

In your harnessProcedural textureMIT

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.

Render of Furrowed tree bark
The render its check recorded in Godot 4.7.2, 256 by 256 pixels.

What it takes and gives

Entry point

Maps
albedo, normal, roughness, height, ao
Parameters
pattern, ridges_across, plate_length, furrow_depth, furrow_width, cross_checks, flakes, lichen and 4 more
Presets
default, pine_plates, ash_ridges, cedar_stringy, mossy_old
Tileable
yes
Command line

Limits. 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.

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
Anisotropic Worley cells for bark plates, Ridged fractal noise stretched along the trunk for interlaced ridges, Domain warping with nearest-pixel warping of cell ids, Terraced flaking from quantized border distance, Height to tangent-space normal by central differences
