title: how to load multi textured object in jpct-ae
body: <p>Right now I can load 3D model with single texture file using jpct-ae successfully.</p>
  
  <pre><code>cube = loadModel(getAssets().open("cube.3ds"), 1);
  TextureManager.getInstance().addTexture("texture.png", new Texture(getAssets().open("texture.png")));
  
  cube.build();
  world.addObject(cube);
  </code></pre>
  
  <p>But now I have to load complex 3D model like car or house which contains multiple texture files. 3D model and texture is being downloaded from server so I cant define textures. 
  How can I load 3d model with multiple textures is jpct-ae ??</p>
