Trolley castors and kart wheels are all pivoted nodes, so the roll clip turns every wheel on the assembly at once. Overall 1.270 x 1.240 x 2.080 m (X x Y x Z), metre units, +Y up, +Z forward, resting on y=0. Named nodes on their own pivots: the four kart wheels and the four trolley castors. Go Kart Track and Pit Lane / karting-lp-v1: faceted grey tarmac and concrete, brushed steel, charcoal rubber, pea gravel and three painted accents in red, blue and yellow, with embedded procedural concrete maps and no custom shaders. Liveries, numbers, boards and signage are invented for this pack and copy no real series, circuit or manufacturer. Rigid node-transform clips: roll. No skinning. No collision or navigation data.","status":"published","url":"https://3dassets.dev/assets/go-kart-track-and-pit-lane-kart-on-trolley-stand-e4a73d48","cdnUrl":"https://cdn.3dassets.dev/assets/34331/v1/model.glb","downloadUrl":"https://3dassets.dev/download/go-kart-track-and-pit-lane-kart-on-trolley-stand-e4a73d48","thumbnailUrl":"https://cdn.3dassets.dev/assets/34331/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/34331/v1/poster.webp","blurhash":"U88hLQEMD4xu?w9ZVX-;00RPt.xuHq.8t-Mw","category":{"slug":"vehicles","title":"Vehicles"},"tags":[{"slug":"modern","title":"Modern"},{"slug":"stylized","title":"Stylized"},{"slug":"interior","title":"Interior"},{"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":57148,"triangles":1256,"vertices":3768,"meshes":15,"materials":4,"textures":0,"animations":["roll"],"boundingBox":{"min":[-0.6352499753236771,-2.98023217215615e-10,-1.0539851374256821],"max":[0.6352499753236771,1.2396170935894342,1.0260000228881836]},"sizeMeters":[1.27,1.24,2.08],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Opus 5","downloads":0,"publishedAt":"2026-09-11T08:04:03.166Z","updatedAt":"2026-09-11T08:04:03.276Z","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/34331/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 KartOnTrolleyStandGoKartTrackAndPitLane(props) {\n  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/34331/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/34331/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/34331/v1/model.glb\" alt=\"Kart on Trolley Stand (Go Kart Track and Pit Lane)\" 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/34331/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/34331/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);\n// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first."}}}
