{"data":{"id":"38177","slug":"rocket-launch-pad-and-gantry-lightning-mast-f79ceca7","title":"Lightning Mast (Rocket Launch Pad and Gantry)","summary":"A 41 m lightning protection mast: a lattice tower on a concrete block, a narrower head section carrying the air terminal spike and the catenary arms, obstruction markers, a ladder the full height and an earth downlead box at the foot.","description":"A 41 m lightning protection mast: a lattice tower on a concrete block, a narrower head section carrying the air terminal spike and the catenary arms, obstruction markers, a ladder the full height and an earth downlead box at the foot. Dimensions 4.40 by 40.90 by 4.40 m (X by Y by Z). Metre units, +Y up, +Z front, origin on the footprint at ground level. Stand three round the pad and run the catenary between their heads. The wire itself is not modelled: a catenary sags, and a rigid node transform cannot bend a mesh. Launch complex palette: pad concrete, flame scorch, galvanised steel, charcoal, vehicle white, cryogenic pale blue, safety red, hazard yellow, glazing and gravel. Static geometry; no rig, animation, 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-lightning-mast-f79ceca7","cdnUrl":"https://cdn.3dassets.dev/assets/38177/v1/model.glb","downloadUrl":"https://3dassets.dev/download/rocket-launch-pad-and-gantry-lightning-mast-f79ceca7","thumbnailUrl":"https://cdn.3dassets.dev/assets/38177/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/38177/v1/poster.webp","blurhash":"U27BDw%M008_00a#~qn$n$jsozbI4nae?vkC","category":{"slug":"roads-infrastructure","title":"Roads & Infrastructure"},"tags":[{"slug":"modern","title":"Modern"},{"slug":"realistic","title":"Realistic"},{"slug":"exterior","title":"Exterior"},{"slug":"kit","title":"Kit / Set"}],"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":108832,"triangles":2492,"vertices":5689,"meshes":4,"materials":4,"textures":0,"animations":[],"boundingBox":{"min":[-2.200000047683716,-0.00006409970849685642,-2.200000047683716],"max":[2.200000047683716,40.900001525878906,2.200000047683716]},"sizeMeters":[4.4,40.9,4.4],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Opus 5","downloads":0,"publishedAt":"2026-09-12T14:03:35.788Z","updatedAt":"2026-09-12T14:03:35.957Z","usage":{"threejs":"import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'\n\nconst loader = new GLTFLoader()\nloader.load('https://cdn.3dassets.dev/assets/38177/v1/model.glb', (gltf) => {\n  scene.add(gltf.scene)\n})","r3f":"import { useGLTF } from '@react-three/drei'\n\nexport function LightningMastRocketLaunchPadAndGantry(props) {\n  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/38177/v1/model.glb')\n  return <primitive object={scene} {...props} />\n}\nuseGLTF.preload('https://cdn.3dassets.dev/assets/38177/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/38177/v1/model.glb\" alt=\"Lightning Mast (Rocket Launch Pad and Gantry)\" 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/38177/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/38177/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);"}}}
