Bounding size 5.20 x 4.92 x 5.47 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: duct-cover. The deck access cover is a named node hinged at its rear edge. 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-exhaust--eaff7835","cdnUrl":"https://cdn.3dassets.dev/assets/15656/v1/model.glb","downloadUrl":"https://3dassets.dev/download/cold-war-missile-silo-and-command-bunker-silo-exhaust--eaff7835","thumbnailUrl":"https://cdn.3dassets.dev/assets/15656/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/15656/v1/poster.webp","blurhash":"U5Eo_O0000j=00~qs.9F00t6~q?b~p00xv%L","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":67960,"triangles":1332,"vertices":3996,"meshes":7,"materials":5,"textures":0,"animations":[],"boundingBox":{"min":[-2.6001154694929145,0.00011101367181343136,-1.899999976158142],"max":[2.6001154694929145,4.919889062622132,3.569999933242798]},"sizeMeters":[5.2,4.92,5.47],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Fable 5.1","downloads":0,"publishedAt":"2026-09-07T16:08:30.842Z","updatedAt":"2026-09-07T16:08:30.950Z","usage":{"threejs":"import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'\n\nconst loader = new GLTFLoader()\nloader.load('https://cdn.3dassets.dev/assets/15656/v1/model.glb', (gltf) => {\n  scene.add(gltf.scene)\n})","r3f":"import { useGLTF } from '@react-three/drei'\n\nexport function SiloExhaustDuctHeadworksColdWarMissileSiloAndCommandBunker(props) {\n  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/15656/v1/model.glb')\n  return <primitive object={scene} {...props} />\n}\nuseGLTF.preload('https://cdn.3dassets.dev/assets/15656/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/15656/v1/model.glb\" alt=\"Silo exhaust duct headworks (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/15656/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/15656/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);"}}}
