How to use two BitmapTextureAtlases in AndEngine?
===

I have to work with big textures in my project so I can't put all the textures into the one `BitmapTextureAtlas`. I tried to put them into two atlases:

    textureAtlas  = new BitmapTextureAtlas(2048, 2048, TextureOptions.BILINEAR_PREMULTIPLYALPHA);
    textureAtlas2 = new BitmapTextureAtlas(1024, 2048, TextureOptions.BILINEAR_PREMULTIPLYALPHA);
    foo = BitmapTextureAtlasTextureRegionFactory.createFromAsset(textureAtlas ,this,"foo.png",0,0);
    bar = BitmapTextureAtlasTextureRegionFactory.createFromAsset(textureAtlas2,this,"bar.png",0,0);

But when I try to use `bar` 

    Sprite sBar = new Sprite(0,0,bar);
    scene.attachChild(sBar);

the only thing I can see is the white rectangle instead of my image. And I have no idea what is wrong here.
