Procedural triplanar rock with surface-gradient bump

Rock material for meshes without usable UVs: layered and ridged noise projected along the three world axes and blended by the normal, with crevice darkening and screen-space bump mapping from the same height.

How it works

Shader type
spatial
Parameters
rock_light (vec4 = 0.58, 0.55, 0.5, 1), rock_dark (vec4 = 0.3, 0.28, 0.26, 1), crevice_color (vec4 = 0.12, 0.11, 0.1, 1), scale (float = 1.6), blend_sharpness (float = 6), crack_amount (float = 0.5), bump_strength (float = 1.2), roughness (float = 0.9)
Result
Grey-brown stone with darker cracks and bumpy lighting that wraps seamlessly around any shape.

Limits to consider

The pattern is fixed in world space: moving the object slides it through the texture (use object space for movable props). Screen-space bumps can shimmer on distant or tiny surfaces and are flat in shadow. Three projections cost three times the noise.
