This Oxidized Concrete Floor PBR set blends a warm umber‑rust patina over aged concrete, featuring fine crazing, faint trowel swirls, and scattered oil marks for grounded industrial realism. The subtle multi‑tone staining reads convincingly in close‑ups while tiling cleanly across warehouses, parking decks, basements, and post‑apocalyptic environments. Delivered as seamless 4K maps—BaseColor, Normal (OpenGL), Roughness, Height/Displacement, and Ambient Occlusion—calibrated for PBR in Blender, Unreal, Unity, 3ds Max, and Maya. Real‑world scale and clean tiling support expansive floors; use Parallax or Displacement to add relief to crack lips and pitted spots, or keep Height light for games. Roughness is tuned for a satin shop‑floor; lower values push fresh spill sheen, higher values yield a dry matte slab. Optimized PNG/TIFF textures preserve crisp stain and micro‑crack detail with efficient memory, and preview renders are included for fast look‑dev.
