A weathered plaster wall with organic moss and algae staining, ideal for damp exteriors, courtyards, basements, and ruins where subtle biological growth adds story and scale to shots. The 8K seamless PBR set includes calibrated Albedo/BaseColor without baked lighting, 16‑bit Normal, Displacement/Height for true surface relief, Roughness, and AO for grounded contact shadows in metal/roughness workflows across major engines. Color variation ranges from muted olive‑green blooms to cool gray plaster with soft trowel undulations, chipped pockets, and micro‑pitting that hold up in closeups while avoiding visible tiling on large walls. Displacement preserves shallow cavities and lifted flakes for convincing silhouettes on trim breaks; recommended use with tessellation or parallax for hero shots, with provided setup tips for Blender, Unreal Engine 5, and Unity HDRP/URP to achieve predictable results fast. Authored to marketplace quality guidelines with organized naming, correct gamma for each map, and lossless sources for clean exports and professional deliverables.​
