{"data":{"id":"13722","slug":"modern-rail-and-metro-network-ballast-hopper-wagon-loa-cbaafcb0","title":"Ballast hopper wagon loaded (Modern Rail and Metro Network)","summary":"The ballast hopper wagon with a heaped load of track ballast in the trough.","description":"The 13.9 m ballast hopper carrying a heaped load of stone ballast, tapering down to the body ends. Wheel flanges rest on y=0 so the rail plane sits at y=0.03; place the vehicle at y=0.57 over a track module to stand it on the railhead. Automatic coupler ports sit at each end at y=1.07. Bounding size 3.24 x 4.51 x 13.92 m (X x Y x Z). Metre units, +Y up, +Z forward, resting at y=0. Named pivot nodes: bogie-front-axle-1-right, bogie-front-axle-1-left, bogie-front-axle-2-right, bogie-front-axle-2-left, bogie-rear-axle-1-right, bogie-rear-axle-1-left, bogie-rear-axle-2-right, bogie-rear-axle-2-left, chute-door-left-1, chute-door-left-2 and 2 more. Rigid node-transform clips: open, close and wheel-roll. No skinning. No collision or navigation data.","status":"published","url":"https://3dassets.dev/assets/modern-rail-and-metro-network-ballast-hopper-wagon-loa-cbaafcb0","cdnUrl":"https://cdn.3dassets.dev/assets/13722/v1/model.glb","downloadUrl":"https://3dassets.dev/download/modern-rail-and-metro-network-ballast-hopper-wagon-loa-cbaafcb0","thumbnailUrl":"https://cdn.3dassets.dev/assets/13722/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/13722/v1/poster.webp","blurhash":"U7AJ~9V[01xt-;9FM|-:00NG_2oz9Z~q%L9G","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":193700,"triangles":5660,"vertices":16980,"meshes":14,"materials":5,"textures":0,"animations":["open","close","wheel-roll"],"boundingBox":{"min":[-1.6203221155267271,-9.536743172944284e-9,-6.960000038146973],"max":[1.6203221155267271,4.510830973840871,6.960000038146973]},"sizeMeters":[3.241,4.511,13.92],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Fable 5.1","downloads":0,"publishedAt":"2026-09-07T15:40:47.212Z","updatedAt":"2026-09-07T15:40:47.310Z","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/13722/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 BallastHopperWagonLoadedModernRailAndMetroNetwork(props) {\n  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/13722/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/13722/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/13722/v1/model.glb\" alt=\"Ballast hopper wagon loaded (Modern Rail and Metro Network)\" 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/13722/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/13722/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);\n// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first."}}}
