Seamless alien mineral surface with a predominantly…: free seamless stone PBR material with albedo, normal, roughness, metalness, height, AO maps. CC0 licensed.
Crafted from the prompt: "Seamless alien mineral surface with a predominantly near-black smooth crystalline base and sparse flowing pale mineral formations. Large irregular branching white and light-grey veins travel organically across broad dark negative spaces, with occasional thicker merged formations and many finer hairline tributaries.
The pale formations should feel embedded within the material rather than painted on top. Include subtle translucent mineral layering, fractured crystalline boundaries, fine internal fissures, restrained cloudy subsurface variation and occasional sharp fracture lines.
Keep the overall composition dark and sparse: approximately 80–85% dark material and 10–15% prominent pale formations. Avoid dense marble coverage.
The surface should feel polished, hard, exotic and slightly metallic, with meaningful roughness variation between the dark body, pale mineral formations and fractures.
Create strong useful PBR information:
- detailed normal information for medium fractures and fine fissures
- height variation concentrated around mineral formations and fractures
- nuanced roughness variation rather than uniform gloss
- restrained ambient occlusion in deeper fracture structures
- predominantly dark metallic response suitable for a polished alien mineral surface
The pattern must be seamless and tileable.
Avoid conventional kitchen marble, obvious stone slabs, regular Voronoi cells, geometric tiling, repeated crack stamps, tree-root shapes, lava, ice, snow, glowing emissive material, painted lines, and uniformly distributed white veins.
The desired hierarchy is broad dark negative space first, sparse flowing pale formations second, fine fracture and crystalline detail third."
