The four fins deploy out to the airstream and fold back, one node each. Dimensions 5.62 by 3.00 by 5.62 m (X by Y by Z). Metre units, +Y up, +Z front, origin on the footprint at ground level. Animated pivot nodes: fin-z-a at (0.00, 0.90, 2.01) m; fin-z-b at (0.00, 0.90, -2.01) m; fin-x-a at (2.01, 0.90, 0.00) m; fin-x-b at (-2.01, 0.90, 0.00) m. Moving nodes are fin-z-a, fin-z-b, fin-x-a and fin-x-b, each hinged at its own fitting 0.9 m up the section. An invented four fin arrangement, not any real vehicle. 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-grid-fin-set-908e6f60","cdnUrl":"https://cdn.3dassets.dev/assets/38188/v1/model.glb","downloadUrl":"https://3dassets.dev/download/rocket-launch-pad-and-gantry-grid-fin-set-908e6f60","thumbnailUrl":"https://cdn.3dassets.dev/assets/38188/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/38188/v1/poster.webp","blurhash":"UGC6.I%M00D%%Mf7M{kC00Ri~qxuIUj@xuWB","category":{"slug":"vehicles","title":"Vehicles"},"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":49952,"triangles":1024,"vertices":2251,"meshes":10,"materials":4,"textures":0,"animations":["open","close"],"boundingBox":{"min":[-2.8099999523162844,0.00004728435906109496,-2.8099999523162844],"max":[2.8099999523162844,2.999952715640939,2.8099999523162844]},"sizeMeters":[5.62,3,5.62],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Opus 5","downloads":0,"publishedAt":"2026-09-12T14:03:42.883Z","updatedAt":"2026-09-12T14:03:42.988Z","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/38188/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 GridFinSetRocketLaunchPadAndGantry(props) {\n  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/38188/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/38188/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/38188/v1/model.glb\" alt=\"Grid Fin Set (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/38188/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/38188/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);\n// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first."}}}
