This Hand‑Laid Basalt Cobblestone PBR set captures dark volcanic stones seated in compacted soil, with chipped edges, vein lines, and subtle depressions for convincing age and traffic wear. Irregular, trapezoid stones avoid grid repetition, while earthy joints add grounded color variation ideal for alleys, plazas, and historic or fantasy towns. Delivered as seamless 4K maps—BaseColor, Normal (OpenGL), Roughness, Height/Displacement, and Ambient Occlusion—calibrated for physically based workflows in Blender, Unreal, Unity, 3ds Max, and Maya. Real‑world scale and clean tiling support large surfaces; push Height for deep joints or use Parallax Occlusion for performance. Roughness is tuned for slightly damp stone; lower values create rainy glints, higher values give dry matte looks. Optimized PNG/TIFF assets balance fidelity and memory, and preview renders are included for rapid look‑dev in archviz and games.
