Create a 3D model of a cyberpunk building: multi-level, with neon signs, exposed wiring, and graffiti. Combine chrome metal, dirty concrete, and holographic screens. Asymmetry, overhanging structures, ventilation pipes. Neon (blue/purple) + warm light accents. Environment: fog, rain, wires between buildings. Optimized for Unreal Engine 5, PBR textures. Style: Cyberpunk 2077, Blade Runner
