The head retracts along the arm and the arm then swings away. Dimensions 10.75 by 5.56 by 1.61 m (X by Y by Z). Metre units, +Y up, +Z front, origin on the footprint at ground level. Animated pivot nodes: fuel-arm at (0.00, 0.00, 0.00) m; qd at (9.10, 4.10, 0.00) m. The origin is at the foot of the column; the girder is 4.1 m up and reaches along +X. Moving nodes are fuel-arm and qd. The flexible hoses a real arm carries are not modelled, because a hose needs a deformable mesh. Launch complex palette: pad concrete, flame scorch, galvanised steel, charcoal, vehicle white, cryogenic pale blue, safety red, hazard yellow, glazing and gravel. Rigid node-transform clips: open and close. No skinning. No collision or navigation data. Invented design: no real launch provider, agency, vehicle, site or mission is named or depicted, and every sign, plate and screen is blank.","status":"published","url":"https://3dassets.dev/assets/rocket-launch-pad-and-gantry-fuelling-arm-4c382846","cdnUrl":"https://cdn.3dassets.dev/assets/38176/v1/model.glb","downloadUrl":"https://3dassets.dev/download/rocket-launch-pad-and-gantry-fuelling-arm-4c382846","thumbnailUrl":"https://cdn.3dassets.dev/assets/38176/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/38176/v1/poster.webp","blurhash":"UKC?lq.8IW%M~oxuD+Rj4mn$R+9Z8{t5-;Rm","category":{"slug":"buildings","title":"Buildings & Architecture"},"tags":[{"slug":"modern","title":"Modern"},{"slug":"realistic","title":"Realistic"},{"slug":"exterior","title":"Exterior"},{"slug":"animated","title":"Animated"}],"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":26680,"triangles":468,"vertices":1036,"meshes":10,"materials":6,"textures":0,"animations":["open","close"],"boundingBox":{"min":[-0.800000011920929,-0.000031290785904775076,-0.810052187156571],"max":[9.949978624697053,5.56005464406323,0.800000011920929]},"sizeMeters":[10.75,5.56,1.61],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Opus 5","downloads":0,"publishedAt":"2026-09-12T14:03:34.413Z","updatedAt":"2026-09-12T14:03:34.527Z","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/38176/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 FuellingArmRocketLaunchPadAndGantry(props) {\n  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/38176/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/38176/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/38176/v1/model.glb\" alt=\"Fuelling Arm (Rocket Launch Pad and Gantry)\" 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/38176/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/38176/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);\n// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first."}}}
