customrendertarget render some meshes to customRenderTarget instead of canvas

I am following this example "http://www.babylonjs.com/demos/customrendertarget/" , but I want to keep the plane(with the texture) in the center but hide the outer balls.

How can I archived this?   I have try to set the balls visibility to false, but the texture in plane will clear too.

    //set the sphere layer mask 
    sphere.layerMask = 2;

and then I got this:

But I am not sure if it is the best way?
