A seamless, tileable sandstone ashlar PBR texture featuring warm beige blocks with heavy granular erosion, pockmarks, and spalled patches revealing friable stone grain for a sun‑worn heritage look. Delivered as calibrated 4K maps—Base Color, Normal, Roughness, Ambient Occlusion, and Height/Displacement—optimized for shadow‑free PBR in Blender, Unreal Engine, Unity HDRP/URP, 3ds Max, Maya, and Substance tools. The height map enables parallax or tessellation to push block relief, chipped edges, and pitted cavities, while tuned roughness captures chalky, dusty mineral micro‑glints with slightly smoother weathered planes. UV‑friendly and non‑directional, it tiles cleanly for forts, temples, courtyards, desert cities, and fantasy keeps; pairs well with decals like cracks, leaks, soot, sand drifts, and moss in damp areas. Optimized PNG/TIFF with clear naming and suggested normal/displacement strengths for quick setup across engines; licensed for games, films, ArchViz, and promotional renders.
