{"data":{"id":"14741","slug":"steam-era-railway-and-rolling-stock-level-crossing-70ed6fd5","title":"Level crossing with gates (Steam Era Railway and Rolling Stock)","summary":"A 4 m level crossing module with a timber road deck, stone approaches and two five bar gates.","description":"A 4 m level crossing: the road surface crosses the track on timber check boards flanked by stone approaches, with a five bar gate hung on each side of the line. Each gate is a named pivot node at its hanging post. Ballast base at y=0, sleeper tops at y=0.35 and railhead top at y=0.50; 1,435 mm gauge with rail centres at x = +/- 0.7525. The module origin sits on the rail-a port at the track centreline and the module runs toward +Z. Bounding size 9.40 x 2.12 x 4.00 m (X x Y x Z). Metre units, +Y up, +Z forward, resting at y=0. Named pivot nodes: gate-1, gate-2. Rigid node-transform clips: open and close. No skinning. No collision or navigation data.","status":"published","url":"https://3dassets.dev/assets/steam-era-railway-and-rolling-stock-level-crossing-70ed6fd5","cdnUrl":"https://cdn.3dassets.dev/assets/14741/v1/model.glb","downloadUrl":"https://3dassets.dev/download/steam-era-railway-and-rolling-stock-level-crossing-70ed6fd5","thumbnailUrl":"https://cdn.3dassets.dev/assets/14741/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/14741/v1/poster.webp","blurhash":"U6DStA?b00I;IT~Wxu0K009F?Zs:-=00IB~p","category":{"slug":"roads-infrastructure","title":"Roads & Infrastructure"},"tags":[{"slug":"historical","title":"Historical"},{"slug":"realistic","title":"Realistic"},{"slug":"modular","title":"Modular"},{"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":44576,"triangles":792,"vertices":2376,"meshes":7,"materials":6,"textures":0,"animations":["open","close"],"boundingBox":{"min":[-4.699999904632568,0.00023651332600849173,0],"max":[4.699999904632568,2.1200777673628908,4]},"sizeMeters":[9.4,2.12,4],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Fable 5.1","downloads":0,"publishedAt":"2026-09-07T15:55:45.860Z","updatedAt":"2026-09-07T15:55:45.961Z","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/14741/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 LevelCrossingWithGatesSteamEraRailwayAndRollingStock(props) {\n  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/14741/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/14741/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/14741/v1/model.glb\" alt=\"Level crossing with gates (Steam Era Railway and Rolling Stock)\" 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/14741/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/14741/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);\n// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first."}}}
