industrial hangar 3d model

Generate a highly accurate, real-world scale (1:1) 3D model based on the provided aerial reference image. The structure is a large aircraft hangar / industrial warehouse with a rectangular footprint and a curved barrel-vault metal roof. The roof is light green / off-white metal, smooth surface, with a central seam line running lengthwise. The building has straight vertical side walls, industrial concrete base, and loading/service access on one long side. Surrounding area includes concrete ground, apron markings, service roads, and parking outlines, kept simple and clean. Maintain true proportions, correct height-to-width ratio, and accurate roof curvature exactly as visible in the reference image (F2F). Architectural style: industrial / airbase hangar, minimal detailing, realistic materials. Output a game-ready, clean topology 3D model, real-world scale in meters, optimized geometry, correct normals, and proper UVs.
