Ultra-detailed 3D model of a large circular blast door from a nuclear bunker, inspired by Fallout style. Reinforced steel construction with radial locking bolts and a central mechanical hub. The surface displays realistic aging: scratches, faded yellow paint, rust patches, and dust accumulation. A bold, engraved identification number (e.g. “VAULT 09”) is visible at the center. Embossed warning signs and riveted plates enhance authenticity. 8K PBR textures with detailed normal, metallic, and roughness maps. Clean UVs, watertight mesh, ideal for cinematic scenes and post-apocalyptic environments., #arch#
