Use it

Code for the specimen as it is set up above; it follows your knobs.

JavaScript

import { createAsset } from 'https://gaitkit.com/cdn/traffic-light.mjs';

const trafficLight = createAsset();
scene.add(trafficLight);                      // rests on y = 0, front faces +Z

JSX

import { useMemo } from 'react';
import { createAsset } from 'https://gaitkit.com/cdn/traffic-light.mjs';

export function TrafficLight() {
  const model = useMemo(() => createAsset(), []);
  return <primitive object={model} />;
}

GDScript

# Import traffic-light.glb (download below). It is a static mesh, one material per colour.
add_child(preload("res://traffic-light.glb").instantiate())

// Import traffic-light.glb with glTFast (com.unity.cloud.gltfast).
// Drop it in the scene: 1 unit = 1 metre, +Z is its front.
