Obsidian Stone

How this texture was made

The stone generator combines a low-frequency FBM for the overall stone body colour with a mid-frequency Voronoi decomposition that breaks the surface into irregular individual stones. Each Voronoi cell is treated as a separate stone and receives its own slight colour offset.

Glossy black volcanic glass with smooth surface and sharp fracture lines. Suited for dark fantasy weapons, mystical artifacts, and dramatic luxury material textures.

Configuration choices

• roughness is set to 0.2, which is at the low end — producing a smoother, more polished finish
• colorVariation is set to 0.15, which is at the low end — producing a tightly uniform palette
• weathering is set to 0.05, which is at the low end — with pristine, fresh-looking output

Palette character

The palette pairs near-black with near-black with indigo tint. It sits in a neutral range with all values held in the dark range.

When this texture fits best

Works on hard-surface contexts — architectural walls, flooring, pavements, industrial backdrops, and any render where a weight-bearing stone or mineral surface is the visual anchor. Stone textures work in both exterior and interior renders — facades, paths, walls, or loose ground.
