Dimensions 8.50 x 3.11 x 9.56 m (width, height, length). Metres, +Y up, nose toward +Z, footprint centred, lowest geometry at y=0. Mechanical pivot nodes: main-rotor/rubber, main-rotor/metal, tail-rotor/rubber, tail-rotor/metal. Static geometry; no animation clips, skeletal rig, collision, navigation or simulation data. Interiors are limited to exposed seats and deck equipment. Other doors and control surfaces are fixed. Boats use keel/skirt baseline, not a waterline. Original generic design.","status":"published","url":"https://3dassets.dev/assets/transport-collection-hd-utility-helicopter-974bf82d","cdnUrl":"https://cdn.3dassets.dev/assets/8021/v1/model.glb","downloadUrl":"https://3dassets.dev/download/transport-collection-hd-utility-helicopter-974bf82d","thumbnailUrl":"https://cdn.3dassets.dev/assets/8021/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/8021/v1/poster.webp","blurhash":"U23l2GI=00-TxDR*bIxa00s._NI;JA$*nhE2","category":{"slug":"vehicles","title":"Vehicles"},"tags":[{"slug":"modern","title":"Modern"},{"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":318800,"triangles":6456,"vertices":19368,"meshes":11,"materials":7,"textures":0,"animations":["rotor-spin"],"boundingBox":{"min":[-4.25,0.00005025191619512093,-4.780000214576721],"max":[4.25,3.1149730682373047,4.78]},"sizeMeters":[8.5,3.115,9.56],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"GPT-6 via Codex; Claude Fable 5.1 brief and frozen geometry kit; Claude Opus 5 animation pass","downloads":0,"publishedAt":"2026-09-06T13:45:36.034Z","updatedAt":"2026-09-06T13:45:36.867Z","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/8021/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 UtilityHelicopterTransportCollectionHD(props) {\n  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/8021/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/8021/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/8021/v1/model.glb\" alt=\"Utility helicopter (Transport Collection HD)\" 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/8021/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/8021/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);\n// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first."}}}
