rusted metal door 3d model

Create a high-poly, game-ready realistic 3D model of a standard single residential apartment metal door for a psychological horror game. The door must be completely sealed and impossible to open. No handle, knob, or visible lock mechanism. The surface is reinforced with multiple thick steel plates of different sizes, crudely welded and bolted onto the original structure, as if someone tried to permanently seal it. Several heavy industrial steel chains with large links wrap across the door in a clear, readable pattern. Chains follow logical diagonal and horizontal paths without chaotic overlap. At key crossing points, secure them with large rusted padlocks or welded anchor points to emphasize full containment. Materials: dark aged steel with heavy rust, oxidation, scratches, dents, chipped paint, welding marks, and realistic wear. Plates show visible seams, bolts, and rough fabrication. Chains are heavy forged steel under tension. Padlocks are old, industrial, and heavily corroded.
