Procedural marble with turbulent veins
In your harnessGodot shaderMIT
Polished marble in object space: veins from a sine of position bent by fractal turbulence, a second finer vein network, cloudy body variation and glossy finish, for floors, statues and counters without textures.
What it takes and gives
- Shader type
- spatial
- Parameters
- body_color (vec4 = 0.92, 0.91, 0.88, 1), cloud_color (vec4 = 0.82, 0.8, 0.78, 1), vein_color (vec4 = 0.25, 0.27, 0.3, 1), scale (float = 1.6), vein_frequency (float = 3.5), turbulence (float = 4.5), vein_sharpness (float = 14), fine_veins (float = 0.4) and 1 more
- Result
- White polished stone with dark grey wandering veins and soft cloudy areas.
- Renderers
- compatibility: compiled and rendered, forward plus: not verified, mobile: not verified
- Placement

Limits. Solid texture in object space: objects that should continue one slab need the same transform. Veins have no depth or translucency. Ten noise octaves per pixel plus fBm make it moderately expensive.
