Snow surface

In your harnessProcedural textureMIT

Generate tileable PBR maps of snow: soft drifts with sparkling glints, wind-carved sastrugi ridges, or old crusted snow with dirt and melt pits. Use for winter ground, roofs and mountains.

Render of Snow surface
The render its check recorded in Godot 4.7.2, 256 by 256 pixels.

What it takes and gives

Entry point
generate
Maps
albedo, normal, roughness, height, ao
Parameters
drift_scale, drift_height, wind_ridges, glints, age, blue_tint, hue_shift, saturation and 1 more
Presets
default, sastrugi, old_crusted, drift_field
Tileable
yes
Command line
python snow_fresh.py --size 1024 --seed 7 --preset NAME --out DIR [--width W --height H] [--set NAME=VALUE] [--directx-normal] [--orm]
Godot material

Blender builder

Limits. Light scattering inside snow is only suggested by a blue tint in the hollows; use a subsurface or translucency setting in the engine for real scattering. Glints are small bright, smooth spots in the maps, not view-dependent sparkle. 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
Low-frequency fractional Brownian motion for drifts, Ridged noise stretched across the wind for sastrugi, Small smooth stamps as glints, Cavity tint from blurred height, Worley distance for melt pits
