Track lane

A component from the Community sports and courts pack, with named material slots for recreation red and recreation white. It measures about 1.20 m × 0.06 m × 4.00 m (W × H × D) and is already minimal, so all three detail files share one geometry. Place it on its own, or load one of the 1 included assembly that use it.

The picture is a studio render. View in 3D loads the GLB files themselves in three.js; switch between high, medium and low to compare.

Included in Community sports and courts (£24), which contains 156 component models and 21 assemblies.

Detail levels	One geometry at every level: 36 triangles is already the minimum for this piece. All three files are included so your loading code can treat it like any other model.
Size (W × H × D)	1.20 m × 0.06 m × 4.00 m
Format	GLB (glTF 2.0 binary)
Compression	Meshopt (EXT_meshopt_compression) + quantised; uncompressed copy in the pack
Textures	4 embedded in the GLB
Material slots	recreation red, recreation white
Sockets	mount-origin, floor-ground, edge-entry, edge-exit
Era	2020s
On mobile	Start with the low level (36 triangles). What a phone can draw depends on your whole scene; no device benchmark is published yet.
Instancing	Safe to instance (InstancedMesh)

Load it in three.js

import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js';
import { MeshoptDecoder } from 'three/addons/libs/meshopt_decoder.module.js';

const loader = new GLTFLoader().setMeshoptDecoder(MeshoptDecoder);
const { scene: model } = await loader.loadAsync('models/sports-track-lane/high-sports-track-lane.glb');
scene.add(model); // 1 unit = 1 metre, origin at the mount socket
