Bounding size 7.54 x 2.48 x 12.89 m (X x Y x Z). Metre units, +Y up, +Z forward, lowest geometry resting on y=0. Movable parts are separate named nodes with local pivots: blast-door. The slab is one named node with a pivot at its own centre so it can be slid the 6.7 m along the track from parked to closed. Generic period hardware with no real designations, insignia or markings. Static geometry; no rig, collision or navigation data.","status":"published","url":"https://3dassets.dev/assets/cold-war-missile-silo-and-command-bunker-silo-blast-do-05555343","cdnUrl":"https://cdn.3dassets.dev/assets/15649/v1/model.glb","downloadUrl":"https://3dassets.dev/download/cold-war-missile-silo-and-command-bunker-silo-blast-do-05555343","thumbnailUrl":"https://cdn.3dassets.dev/assets/15649/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/15649/v1/poster.webp","blurhash":"U4A^OGlB00?QD$E3t8%J00v{?b9J?d?Cs*V~","category":{"slug":"buildings","title":"Buildings & Architecture"},"tags":[{"slug":"historical","title":"Historical"},{"slug":"realistic","title":"Realistic"},{"slug":"exterior","title":"Exterior"}],"license":{"slug":"cc0-1.0","name":"CC0 1.0 Universal","url":"https://creativecommons.org/publicdomain/zero/1.0/","attributionRequired":false},"contributor":{"username":"3dassets","name":"3D Assets","url":"https://3dassets.dev/u/3dassets"},"stats":{"fileSize":88992,"triangles":1748,"vertices":5244,"meshes":8,"materials":5,"textures":0,"animations":[],"boundingBox":{"min":[-3.7699999809265137,-0.0002008271545865803,-6.21975284964542],"max":[3.7699999809265137,2.4851828235521864,6.67000681774935]},"sizeMeters":[7.54,2.485,12.89],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Fable 5.1","downloads":0,"publishedAt":"2026-09-07T16:08:27.451Z","updatedAt":"2026-09-07T16:08:27.566Z","usage":{"threejs":"import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'\n\nconst loader = new GLTFLoader()\nloader.load('https://cdn.3dassets.dev/assets/15649/v1/model.glb', (gltf) => {\n  scene.add(gltf.scene)\n})","r3f":"import { useGLTF } from '@react-three/drei'\n\nexport function SlidingSiloBlastDoorColdWarMissileSiloAndCommandBunker(props) {\n  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/15649/v1/model.glb')\n  return <primitive object={scene} {...props} />\n}\nuseGLTF.preload('https://cdn.3dassets.dev/assets/15649/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/15649/v1/model.glb\" alt=\"Sliding silo blast door (Cold War Missile Silo and Command Bunker)\" camera-controls auto-rotate></model-viewer>","blender":"# Blender 4.x: File > Import > glTF 2.0, or from the Python console after downloading the file.\nimport bpy\nbpy.ops.import_scene.gltf(filepath='model.glb')  # from https://cdn.3dassets.dev/assets/15649/v1/model.glb\n# Metres and +Y up are converted to Blender's Z-up scene automatically.","godot":"# Godot 4: copy model.glb into res://models/ and the editor imports it as a scene.\nvar packed := load(\"res://models/model.glb\") as PackedScene\nvar model := packed.instantiate()\nadd_child(model)","unity":"// Unity: import model.glb with glTFast (Package Manager: com.unity.cloud.gltfast) and drag the prefab in,\n// or load it at runtime straight from the CDN:\nusing GLTFast;\nvar gltf = new GltfImport();\nif (await gltf.Load(\"https://cdn.3dassets.dev/assets/15649/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);"}}}
