Stack a segment per stage. Dimensions 2.88 by 3.53 by 2.88 m (X by Y by Z). Metre units, +Y up, +Z front, origin on the footprint at ground level. The handrail is faceted into one straight run per tread, which is what a flat shaded helix is. Coast low-poly palette: lighthouse white, signal red, granite, wet shore rock, clifftop grass, timber, iron and sea. Flat shaded, no textures. Static geometry; no rig, animation, collision or navigation data.","status":"published","url":"https://3dassets.dev/assets/lighthouse-and-rocky-coast-lighthouse-spiral-stair-seg-b5701343","cdnUrl":"https://cdn.3dassets.dev/assets/36592/v1/model.glb","downloadUrl":"https://3dassets.dev/download/lighthouse-and-rocky-coast-lighthouse-spiral-stair-seg-b5701343","thumbnailUrl":"https://cdn.3dassets.dev/assets/36592/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/36592/v1/poster.webp","blurhash":"U15}v{-=00Dh-;RkIUxs009F~q_N4n%N?bD$","category":{"slug":"buildings","title":"Buildings & Architecture"},"tags":[{"slug":"historical","title":"Historical"},{"slug":"low-poly","title":"Low Poly"},{"slug":"interior","title":"Interior"},{"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":24944,"triangles":496,"vertices":1488,"meshes":1,"materials":1,"textures":0,"animations":[],"boundingBox":{"min":[-1.4400419018639452,0,-1.4374595425674432],"max":[1.4400419018639452,3.5256736278533936,1.4374595425674432]},"sizeMeters":[2.88,3.526,2.875],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Opus 5","downloads":0,"publishedAt":"2026-09-11T22:10:01.546Z","updatedAt":"2026-09-11T22:10:01.659Z","usage":{"threejs":"import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'\n\nconst loader = new GLTFLoader()\nloader.load('https://cdn.3dassets.dev/assets/36592/v1/model.glb', (gltf) => {\n  scene.add(gltf.scene)\n})","r3f":"import { useGLTF } from '@react-three/drei'\n\nexport function LighthouseSpiralStairSegmentLighthouseAndRockyCoast(props) {\n  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/36592/v1/model.glb')\n  return <primitive object={scene} {...props} />\n}\nuseGLTF.preload('https://cdn.3dassets.dev/assets/36592/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/36592/v1/model.glb\" alt=\"Lighthouse Spiral Stair Segment (Lighthouse and Rocky Coast)\" 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/36592/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/36592/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);"}}}
