Marble & Stone Textures for Unity
Browse 70 free seamless marble & stone textures optimized for Unity. Every texture downloads as PNG at 1024px, 2048px, or 4096px — power-of-two sizes that Unity handles efficiently with mipmapping and texture compression. All textures tile perfectly with no visible seams.
Marble and stone textures — marble, concrete, cobblestone, asphalt, plaster, and terrazzo — are essential for architectural visualization, environmental design, and any workflow requiring natural hard surfaces. In Unity, import the PNG into your Assets folder and assign it to the Albedo (Base Map) slot in a Lit (URP) or HDRP material — set the Wrap Mode to Repeat for seamless tiling. All textures are procedurally generated and released under our royalty-free license — free for personal and commercial projects with no attribution required.
Marble & Stone Textures
Workflow in Unity
In Unity, import any texture as sRGB for base colour maps and as linear for normal, roughness, metallic, and AO maps — the compression and colour space choices matter enormously for PBR accuracy. The Standard shader expects metallic intensity in the alpha channel of the metallic map, which is a common gotcha. For mobile targets, compress to ASTC (iOS and newer Android) or ETC2 (fallback) rather than shipping uncompressed PNGs; the visual difference is negligible and the VRAM savings are substantial. Scale each texture's UV tiling so that one tile covers about 1 to 2 metres of surface in-game, which keeps pixel density consistent across objects.
Quality notes for marble & stone textures
Hard-surface textures (marble, stone, concrete, cobblestone, asphalt, plaster, terrazzo) all share a requirement for accurate scaling. Too-small tiles read as decorative rather than structural; too-large tiles reveal the repeating pattern. Target a UV scale that produces stones roughly 10 to 25 centimetres apart for floor and wall materials. For distant views, higher tile frequencies read cleanly; for close-ups, larger individual stones with more per-tile detail serve better.
Unity × Marble & Stone specifics
In Unity, marble and other hard-surface textures look best with a slight AO map — Unity's Standard shader includes an Occlusion slot specifically for this. Derive an AO map from the base colour using the Palette Extractor and a slight blur, or author it manually in Substance Painter. Without an AO map, marble veining can read as flat decal rather than actual stone.
