A realistic concrete chess floor material featuring a classic checkerboard pattern with subtle surface wear and roughness variation. This material combines two concrete tones arranged in a chess-style layout, enhanced with fine surface imperfections, micro bumps, and natural roughness differences to avoid a flat or overly clean appearance. The bump details add depth to the concrete texture while keeping the surface physically plausible. Built using a clean, non-destructive node setup and fully PBR-compatible, the material performs consistently in both Cycles and Eevee. Proper UV mapping is required to maintain uniform tile scale and correct pattern alignment. Ideal for interior floors, architectural visualization, game environments, industrial spaces, corridors, and stylized or realistic scenes requiring a concrete checkerboard surface.
