Basalt Cobbles Cobblestone

How this texture was made

The cobblestone generator uses Voronoi decomposition to partition the tile into stones, then applies per-cell colour variation and a subtle dome-shading to each stone. The dome effect is produced by measuring the distance from each pixel to the nearest cell centre and using that distance as the basis for a radial gradient — pixels near the centre are brightest (light catches the stone's apex), pixels near the cell edge are darker (shadow at the groove).

Dark volcanic basalt cobblestones with subtle color shifts and rough surfaces. Ideal for dramatic fortress courtyards and moody urban environments.

Configuration choices

• stoneSize is set to 40, which is high — with large, visibly distinct stones
• roughness is set to 0.6, which sits in the mid range — balanced surface detail
• colorVariation is set to 0.2, which is at the low end — producing a tightly uniform palette

Palette character

The palette spans near-black, deep dusty grey, dusty grey. It sits in a neutral range with visible contrast between lighter and darker zones.

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. Cobblestone works well in European architectural contexts and anywhere a walkable period surface is needed.
