{"data":{"id":"32843","slug":"aircraft-fleet-and-airfield-perimeter-gate-59ca11d0","title":"Perimeter Gate, Double Leaf (Aircraft Fleet and Airfield)","summary":"An 8 metre double leaf perimeter gate on two heavy posts, matching the fence bay height. Premium CC0 aircraft and airfield game asset.","description":"An 8 metre double leaf perimeter gate on two heavy posts, matching the fence bay height. Each leaf swings outward on its own hinge node. Dimensions 8.00 x 2.70 x 0.21 m (X x Y x Z). Origin at the footprint centre, resting on y = 0; metres, +Y up, nose toward +Z, wing span and wheel axles along X. Named pivots: gate-right at (3.92, 0, -0.03); gate-left at (-3.92, 0, -0.03). Connectors: e fence at (4, 0, 0) facing +X; w fence at (-4, 0, 0) facing -X. Rigid node-transform clips open, close drive named nodes on their own pivots. No skinning and no skeleton, so the retraction linkage, rotor flapping and lead-lag, propeller pitch change, the swashplate and wing flex are all deliberately static. Sixteen material palette of airframe white, deep blue, warm red, airfield yellow, bare aluminium, steel grey, charcoal, near black tarmac, light grey concrete, olive and tinted glazing, plus five emissive lighting materials for navigation, strobe, taxiway, threshold and interior lights. Flat colours, no texture maps. Original generic design with no manufacturer, type designation, livery, registration or operator marking. Free 3D model for Unity, Godot, Unreal, three.js and Blender. No collision or navigation data.","status":"published","url":"https://3dassets.dev/assets/aircraft-fleet-and-airfield-perimeter-gate-59ca11d0","cdnUrl":"https://cdn.3dassets.dev/assets/32843/v1/model.glb","downloadUrl":"https://3dassets.dev/download/aircraft-fleet-and-airfield-perimeter-gate-59ca11d0","thumbnailUrl":"https://cdn.3dassets.dev/assets/32843/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/32843/v1/poster.webp","blurhash":"U497khs:4-D*%3_Nt6In00%M_3xWR#9FV|xt","category":{"slug":"roads-infrastructure","title":"Roads & Infrastructure"},"tags":[{"slug":"modern","title":"Modern"},{"slug":"realistic","title":"Realistic"},{"slug":"exterior","title":"Exterior"},{"slug":"animated","title":"Animated"},{"slug":"modular","title":"Modular"}],"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":16316,"triangles":352,"vertices":818,"meshes":5,"materials":2,"textures":0,"animations":["open","close"],"boundingBox":{"min":[-4,-0.000025904561619327637,-0.10508056737490051],"max":[4,2.6997726609462616,0.10498931580222148]},"sizeMeters":[8,2.7,0.21],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"claude-opus-5","downloads":1,"publishedAt":"2026-09-08T13:05:22.560Z","updatedAt":"2026-09-08T15:01:44.717Z","usage":{"threejs":"import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'\nimport { AnimationMixer } from 'three'\n\nlet mixer\n\nconst loader = new GLTFLoader()\nloader.load('https://cdn.3dassets.dev/assets/32843/v1/model.glb', (gltf) => {\n  scene.add(gltf.scene)\n  mixer = new AnimationMixer(gltf.scene)\n  mixer.clipAction(gltf.animations[0]).play()\n})\n\n// Call from your render loop; deltaSeconds is time since the previous frame.\nfunction updateAssetAnimation(deltaSeconds) {\n  mixer?.update(deltaSeconds)\n}","r3f":"import { useGLTF, useAnimations } from '@react-three/drei'\nimport { useEffect } from 'react'\n\nexport function PerimeterGateDoubleLeafAircraftFleetAndAirfield(props) {\n  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/32843/v1/model.glb')\n  const { actions, names } = useAnimations(animations, scene)\n  useEffect(() => {\n    const action = actions[names[0]]\n    action?.reset().play()\n    return () => { action?.stop() }\n  }, [actions, names])\n  return <primitive object={scene} {...props} />\n}\nuseGLTF.preload('https://cdn.3dassets.dev/assets/32843/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/32843/v1/model.glb\" alt=\"Perimeter Gate, Double Leaf (Aircraft Fleet and Airfield)\" camera-controls auto-rotate autoplay></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/32843/v1/model.glb\n# Metres and +Y up are converted to Blender's Z-up scene automatically.\n# Clips arrive as actions; play them from the Dope Sheet > Action Editor.","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)\nvar player := model.find_child(\"AnimationPlayer\", true, false) as AnimationPlayer\nplayer.play(player.get_animation_list()[0])","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/32843/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);\n// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first."}}}
