A modern wallpaper that mimics staggered 3D blocks in soft silver‑gray, layered over a hand‑troweled concrete texture for subtle depth without heavy contrast . Each “panel” features gentle top‑edge shading and brushed micro‑scratches that read convincingly in closeups and create a sophisticated rhythm in wide shots . Package includes 4K+ seamless JPEG and PNG, plus a calibrated grayscale bump/height map derived from the panel ledges and plaster grain to deliver believable micro‑shadowing . Optimized for Blender, 3ds Max, V‑Ray, Corona, Cycles, Unreal/Unity—use as Base Color, set bump 0.1–0.22, and follow included meter‑scale notes to keep block height and spacing consistent across engines and print . Clean tiling enables full‑wall coverage and feature niches with artifact‑free results in production renders .
