Three JS: CTM file not loading - three.js

Question

Here I tried to load a .ctm file in three JS using CTM Loader. But the CTM file is not getting loaded and the object is not visible in the screen, whereas when I load the js file with geometry properties it gets loaded and the object is visible on the screen. So, when I tried to load a ctm file the object is not visible and when I load a js file with geometry properties the object gets loaded.
I have attached the code below
var SCREEN_WIDTH = window.innerWidth;
var SCREEN_HEIGHT = window.innerHeight;
var FLOOR = -250;
var container;
var camera, scene, controls;
var renderer;
var mesh;
var textureCube;
var mouseX = 0, mouseY = 0;
var windowHalfX = window.innerWidth / 2;
var windowHalfY = window.innerHeight / 2;
init();
animate();
function init() {
container = document.createElement('div');
document.body.appendChild(container);
camera = new THREE.PerspectiveCamera(30, SCREEN_WIDTH / SCREEN_HEIGHT, 1, 10000);
camera.position.set(185, 40, 170);
controls = new THREE.OrbitControls(camera);
controls.maxPolarAngle = Math.PI / 2;
controls.minDistance = 150;
controls.maxDistance = 500;
scene = new THREE.Scene();
scene.background = textureCube;
var light = new THREE.PointLight(0xffffff, 1);
light.position.set(2, 5, 1);
light.position.multiplyScalar(30);
scene.add(light);
var light = new THREE.PointLight(0xffffff, 0.75);
light.position.set(-12, 4.6, 2.4);
light.position.multiplyScalar(30);
scene.add(light);
scene.add(new THREE.AmbientLight(0x050505));
renderer = new THREE.WebGLRenderer({ antialias: true });
renderer.setPixelRatio(window.devicePixelRatio);
renderer.setSize(SCREEN_WIDTH, SCREEN_HEIGHT);
renderer.domElement.style.position = "relative";
container.appendChild(renderer.domElement);
renderer.gammaInput = true;
renderer.gammaOutput = true;
window.addEventListener('resize', onWindowResize, false);
window.addEventListener('mousemove', onDocumentMouseMove, false);
var start = Date.now();
var position = new THREE.Vector3(-105, -78, -30);
var scale = new THREE.Vector3(30, 30, 30);
var loader = new THREE.CTMLoader(true);
// loader.loadParts("models/ctm/camaro/camaro.js", function (geometries, materials) {
loader.load("models/ctm/camaro/camaro.ctm", function (geometries, materials) {
for (var i = 0; i < geometries.length; i++) {
var mesh = new THREE.Mesh(geometries[i], materials[i]);
mesh.name = "camaro car"
mesh.position.copy(position);
mesh.scale.copy(scale);
scene.add(mesh);
}
var end = Date.now();
console.log("load time:", end - start, "ms");
}, { useWorker: true });
}
function onWindowResize(event) {
SCREEN_WIDTH = window.innerWidth;
SCREEN_HEIGHT = window.innerHeight;
renderer.setSize(SCREEN_WIDTH, SCREEN_HEIGHT);
camera.aspect = SCREEN_WIDTH / SCREEN_HEIGHT;
camera.updateProjectionMatrix();
}
function onDocumentMouseMove(event) {
mouseX = (event.clientX - windowHalfX);
mouseY = (event.clientY - windowHalfY);
}
function animate() {
requestAnimationFrame(animate);
render();
}
function render() {
renderer.render(scene, camera);
}
