title: JSON model texture not loading
body: <p>I've converted obj file to json model using python tool
  and i'm trying to load it 
  here is the code </p>
  
  <pre><code>var camera, scene, renderer;
  var mesh, aircraft;
  
  function addModelToScene( geometry, materials )
  {
      aircraft = new THREE.Mesh( geometry, new THREE.MeshFaceMaterial( materials ) );
      scene.add( aircraft );
  }
  
  function init()
  {
      camera = new THREE.PerspectiveCamera( 45, window.innerWidth / window.innerHeight, 0.1, 20000 );
      camera.position.z = 30;
      scene = new THREE.Scene();
  
  var jsonLoader = new THREE.JSONLoader( true );
  jsonLoader.load( "XA-20.js", addModelToScene );
  renderer = new THREE.WebGLRenderer();
  renderer.setSize( window.innerWidth, window.innerHeight );
  document.body.appendChild( renderer.domElement );
  }
  
  function animate()
  {
      requestAnimationFrame( animate );
      aircraft.rotation.y += 0.02;
      renderer.render( scene, camera );
  }

  <p>model is loading but no textures on it 
  model file is big so I can't post it here
  but there are materials</p>
