{"data":{"id":"28838","slug":"medieval-siege-and-castle-defence-assault-gate-4m-e03bd748","title":"Iron Bound Gate Bay 4 m (Medieval Siege and Castle Defence)","summary":"Gate bay on the wall grid: an arched tunnel, two iron bound oak leaves on their hinges and a drawbar that slides into the wall socket.","description":"The gate bay of the wall run. A 1.8 m arched tunnel through a 4 m bay carries two oak leaves strapped and studded in iron, hung on the jambs, with a squared drawbar behind them that slides into a socket cut in the pier. The gate clips swing both leaves together and the bar clips run it into and out of its socket, so the bay reads shut, barred or forced. Dimensions 4.10 × 4.60 × 2.47 m (X × Y × Z). Pivot on the grid origin with named connector ports. Metre units, +Y up, +Z forward. Kingdom limestone, ashlar, timber, oak, iron, cloth, slate and straw, the palette shared with the castle construction and faction building packs. Rigid node-transform clips gate-open, gate-close, bar-open, bar-close turn named parts on their own pivots. No skinning, no skeleton, no collision or navigation data.","status":"published","url":"https://3dassets.dev/assets/medieval-siege-and-castle-defence-assault-gate-4m-e03bd748","cdnUrl":"https://cdn.3dassets.dev/assets/28838/v1/model.glb","downloadUrl":"https://3dassets.dev/download/medieval-siege-and-castle-defence-assault-gate-4m-e03bd748","thumbnailUrl":"https://cdn.3dassets.dev/assets/28838/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/28838/v1/poster.webp","blurhash":"UFHV3Z~q00IVfT-pt7IU00M{s:IUIUt7%MM{","category":{"slug":"buildings","title":"Buildings & Architecture"},"tags":[{"slug":"medieval","title":"Medieval"},{"slug":"low-poly","title":"Low Poly"},{"slug":"kit","title":"Kit / Set"},{"slug":"animated","title":"Animated"},{"slug":"modular","title":"Modular"}],"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":54756,"triangles":1048,"vertices":3144,"meshes":8,"materials":4,"textures":0,"animations":["gate-open","gate-close","bar-open","bar-close"],"boundingBox":{"min":[-2.049999952316284,0,-1.2700036371871044],"max":[2.049999952316284,4.599999904632568,1.2013336309206606]},"sizeMeters":[4.1,4.6,2.471],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Fable 5.1","downloads":0,"publishedAt":"2026-09-08T03:57:27.653Z","updatedAt":"2026-09-08T03:57:27.747Z","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/28838/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 IronBoundGateBay4MMedievalSiegeAndCastleDefence(props) {\n  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/28838/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/28838/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/28838/v1/model.glb\" alt=\"Iron Bound Gate Bay 4 m (Medieval Siege and Castle Defence)\" 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/28838/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/28838/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);\n// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first."}}}
