Mirror the placement rotation to turn right. 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 4.55 x 0.50 x 4.41 m (X x Y x Z). Metre units, +Y up, +Z forward, resting at y=0. Static geometry; no rig, collision or navigation data.","status":"published","url":"https://3dassets.dev/assets/steam-era-railway-and-rolling-stock-track-curve-15deg-43b236be","cdnUrl":"https://cdn.3dassets.dev/assets/14738/v1/model.glb","downloadUrl":"https://3dassets.dev/download/steam-era-railway-and-rolling-stock-track-curve-15deg-43b236be","thumbnailUrl":"https://cdn.3dassets.dev/assets/14738/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/14738/v1/poster.webp","blurhash":"U8BDQVIU00V@RPWCozt600%M~pof%NoeRPRk","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":37880,"triangles":720,"vertices":2160,"meshes":4,"materials":4,"textures":0,"animations":[],"boundingBox":{"min":[-2.4996767044067383,0.00003794698367481919,-0.033520029228137904],"max":[2.0497255325317383,0.4999232221534957,4.380373415838884]},"sizeMeters":[4.549,0.5,4.414],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Fable 5.1","downloads":0,"publishedAt":"2026-09-07T15:55:45.523Z","updatedAt":"2026-09-07T15:55:45.639Z","usage":{"threejs":"import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'\n\nconst loader = new GLTFLoader()\nloader.load('https://cdn.3dassets.dev/assets/14738/v1/model.glb', (gltf) => {\n  scene.add(gltf.scene)\n})","r3f":"import { useGLTF } from '@react-three/drei'\n\nexport function PlainTrackCurve15DegreesSteamEraRailwayAndRollingStock(props) {\n  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/14738/v1/model.glb')\n  return <primitive object={scene} {...props} />\n}\nuseGLTF.preload('https://cdn.3dassets.dev/assets/14738/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/14738/v1/model.glb\" alt=\"Plain track curve 15 degrees (Steam Era Railway and Rolling Stock)\" camera-controls auto-rotate></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/14738/v1/model.glb\n# Metres and +Y up are converted to Blender's Z-up scene automatically.","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)","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/14738/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);"}}}
