Sand ripples and dunes
In your harnessProcedural textureMIT
Generate tileable PBR maps of sand with wind or water ripples: asymmetric crests that bend, fork and merge, dark minerals in the troughs, optional dune swells and wet sand. Use for beaches, deserts and riverbeds.

What it takes and gives
- Entry point
- generate
- Maps
- albedo, normal, roughness, height, ao
- Parameters
- ripples, direction, meander, asymmetry, dune_swell, trough_minerals, wetness, hue_shift and 2 more
- Presets
- default, tidal_wet, desert_dunes, white_gypsum
- Tileable
- yes
- Command line
- python sand_ripples.py --size 1024 --seed 7 --preset NAME --out DIR [--width W --height H] [--set NAME=VALUE] [--directx-normal] [--orm]
- Godot material
- material.tres
- Blender builder
- blender_material.build_material(folder)
Limits. Ripple direction is limited to four whole-tile directions so the texture repeats. Ripples are a phase field, not a sediment simulation, and do not respond to obstacles. Dune swells are low-frequency height only. Occlusion is a blurred-height estimate.
