Dimensions 1.03 by 2.04 by 5.10 m (X by Y by Z). Metre units, +Y up, +Z front, origin on the footprint at ground level. Animated pivot nodes: wheel-tfr at (0.42, 0.24, 2.42) m; wheel-tfl at (-0.42, 0.24, 2.42) m; wheel-trr at (0.42, 0.24, 1.34) m; wheel-trl at (-0.42, 0.24, 1.34) m; wheel-0fr at (0.40, 0.18, 0.86) m; wheel-0fl at (-0.40, 0.18, 0.86) m; wheel-0rr at (0.40, 0.18, -0.26) m; wheel-0rl at (-0.40, 0.18, -0.26) m; wheel-1fr at (0.40, 0.18, -1.04) m; wheel-1fl at (-0.40, 0.18, -1.04) m; wheel-1rr at (0.40, 0.18, -2.16) m; wheel-1rl at (-0.40, 0.18, -2.16) m. A blue tow tractor 2.09 m tall with a canopy and a lit beacon, coupled to two orange trolleys carrying stacked parts containers. All twelve wheels turn on the roll clip. The drawbars, the couplings and the containers are fixed geometry, and the tractor has no driver: the seated worker figure in this pack is a separate model. Car plant palette: light grey epoxy floor, safety yellow, white plant steel, charcoal, safety orange, equipment blue, two gloss body colours, matt primer, skin, glass and emissive amber. Standard PBR materials with embedded procedural maps. Rigid node-transform clips: roll. No skinning. No collision or navigation data.","status":"published","url":"https://3dassets.dev/assets/car-factory-production-line-tugger-train-tractor-1875ccc7","cdnUrl":"https://cdn.3dassets.dev/assets/27857/v1/model.glb","downloadUrl":"https://3dassets.dev/download/car-factory-production-line-tugger-train-tractor-1875ccc7","thumbnailUrl":"https://cdn.3dassets.dev/assets/27857/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/27857/v1/poster.webp","blurhash":"U7AwSO6q9Faz-g4nwHSj00,,~Wo|4p_3OZwZ","category":{"slug":"vehicles","title":"Vehicles"},"tags":[{"slug":"modern","title":"Modern"},{"slug":"stylized","title":"Stylized"},{"slug":"interior","title":"Interior"},{"slug":"kit","title":"Kit / Set"},{"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":68600,"triangles":3336,"vertices":4052,"meshes":27,"materials":5,"textures":0,"animations":["roll"],"boundingBox":{"min":[-0.5149987386872793,-9.536743172944284e-9,-2.3499999046325684],"max":[0.5149987386872793,2.04499917675577,2.75]},"sizeMeters":[1.03,2.045,5.1],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Fable 5.1","downloads":8,"publishedAt":"2026-09-08T00:58:05.910Z","updatedAt":"2026-09-08T04:17:23.492Z","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/27857/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 TuggerTrainTractorCarFactoryProductionLine(props) {\n  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/27857/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/27857/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/27857/v1/model.glb\" alt=\"Tugger Train Tractor (Car Factory Production Line)\" 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/27857/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/27857/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);\n// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first."}}}
