Free 3D model for theme park, roller coaster and tycoon game scenes in Unity, Godot, Unreal, three.js and Blender. Overall 1.06 by 10.88 by 6.48 m (X by Y by Z). Metre units, +Y up, +Z forward. Pivot on the grid origin at the level entry. The loop advances 4 m along +Z over the full revolution, so the two halves close into a loop whose exit clears its entry by 4 m. Static geometry; no rig, collision or navigation data.","status":"published","url":"https://3dassets.dev/assets/theme-park-rides-and-coasters-theme-park-rides-and-coa-376ae2af","cdnUrl":"https://cdn.3dassets.dev/assets/28631/v1/model.glb","downloadUrl":"https://3dassets.dev/download/theme-park-rides-and-coasters-theme-park-rides-and-coa-376ae2af","thumbnailUrl":"https://cdn.3dassets.dev/assets/28631/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/28631/v1/poster.webp","blurhash":"U46@ym^m000c?IxuD$E09r9YWB^-xuInIU?I","category":{"slug":"roads-infrastructure","title":"Roads & Infrastructure"},"tags":[{"slug":"cute","title":"Cute"},{"slug":"stylized","title":"Stylized"},{"slug":"modular","title":"Modular"},{"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":57232,"triangles":1148,"vertices":2953,"meshes":3,"materials":3,"textures":0,"animations":[],"boundingBox":{"min":[-0.5299111953346891,0,-0.0009547751185676745],"max":[0.5299111953346891,10.880000114440918,6.479710652371491]},"sizeMeters":[1.06,10.88,6.481],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Fable 5.1","downloads":0,"publishedAt":"2026-09-08T03:56:32.825Z","updatedAt":"2026-09-08T03:56:32.942Z","usage":{"threejs":"import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'\n\nconst loader = new GLTFLoader()\nloader.load('https://cdn.3dassets.dev/assets/28631/v1/model.glb', (gltf) => {\n  scene.add(gltf.scene)\n})","r3f":"import { useGLTF } from '@react-three/drei'\n\nexport function CoasterVerticalLoopLowerHalfThemeParkRidesAndCoasters(props) {\n  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/28631/v1/model.glb')\n  return <primitive object={scene} {...props} />\n}\nuseGLTF.preload('https://cdn.3dassets.dev/assets/28631/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/28631/v1/model.glb\" alt=\"Coaster Vertical Loop Lower Half (Theme Park Rides and Coasters)\" 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/28631/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/28631/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);"}}}
