I have an issue with OBJ Loader in THREE.JS.  

I've wrote the following code:

```
   //Scene
scene = new THREE.Scene();

//Camera
camera = new THREE.PerspectiveCamera(60,window.innerWidth/window.innerHeight,1,1000);

//Renderer
renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth-5,window.innerHeight-5);
document.getElementById('container').appendChild(renderer.domElement);

//loader
loader = new THREE.OBJLoader();
loader.load('../disk.obj',function(object){
   scene.add(object);
});
//Main loop
function init() {
   renderer.render(camera,scene);
}

```

Can you help me?
