This Dark Slate Cobblestone Squares PBR set captures hand‑cut slate blocks with varied cleft surfaces, chipped edges, and moss‑tinted joints for grounded realism in historic alleys, plazas, and castle courtyards. The tight grid layout reads cleanly at distance while subtle height undulation and micro veining hold up in close‑ups, avoiding visible repetition on large grounds. Included are seamless 4K maps—BaseColor, Normal (OpenGL), Roughness, Height/Displacement, and Ambient Occlusion—calibrated for Blender, Unreal, Unity, 3ds Max, and Maya in physically based workflows. Real‑world scale and clean tiling support expansive coverage; drive deeper grout with Displacement or use Parallax for performance in games. Roughness is tuned for a slightly damp stone sheen; lower for rain‑wet reflections, higher for dry, matte medieval stone. Optimized PNG/TIFF textures balance crisp detail with efficient memory, and preview renders are provided for fast look‑dev in archviz and cinematic environments.
