The arm is a named node on the head rail pivot. Overall 1.300 x 1.360 x 0.900 m (X x Y x Z), metre units, +Y up, +Z forward, resting on y=0. Named nodes on their own pivots: holder-arm, wheel-gate-left, wheel-gate-right. Velodrome and Track Cycling / velodrome-lp-v1: faceted pale pine track boards, grey concrete, brushed steel, charcoal rubber and three painted accents in blue, red and yellow, with embedded procedural wood and concrete maps and no custom shaders. There are no people in this pack, and every screen, board, banner and panel face is blank: nothing here names or depicts a real venue, team, race or manufacturer. Rigid node-transform clips: open, close and roll. No skinning. No collision or navigation data.","status":"published","url":"https://3dassets.dev/assets/velodrome-and-track-cycling-starting-gate-with-holder--a8df2a73","cdnUrl":"https://cdn.3dassets.dev/assets/37989/v1/model.glb","downloadUrl":"https://3dassets.dev/download/velodrome-and-track-cycling-starting-gate-with-holder--a8df2a73","thumbnailUrl":"https://cdn.3dassets.dev/assets/37989/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/37989/v1/poster.webp","blurhash":"U6AmMJIo00-CX+xZQ.E30e%M}s9Z+Io#K%n3","category":{"slug":"props","title":"Props & Furniture"},"tags":[{"slug":"modern","title":"Modern"},{"slug":"stylized","title":"Stylized"},{"slug":"interior","title":"Interior"},{"slug":"animated","title":"Animated"}],"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":15192,"triangles":232,"vertices":696,"meshes":9,"materials":4,"textures":0,"animations":["open","close","roll"],"boundingBox":{"min":[-0.6499999761581421,-3.5762786898541066e-9,-0.4500228723753658],"max":[0.6499999761581421,1.3599996781256047,0.4500228723753658]},"sizeMeters":[1.3,1.36,0.9],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Opus 5","downloads":0,"publishedAt":"2026-09-12T06:37:32.318Z","updatedAt":"2026-09-12T06:37:32.416Z","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/37989/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 StartingGateWithHolderFrameVelodromeAndTrackCycling(props) {\n  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/37989/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/37989/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/37989/v1/model.glb\" alt=\"Starting Gate with Holder Frame (Velodrome and Track Cycling)\" 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/37989/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/37989/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);\n// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first."}}}
