I have a plane with a movie material

plane.material = new MovieMaterial((movieClip_mc);

the plane has

plane.rotationX = 45;

I need to show movieClip_mc (movie clip of the material) in 2d layer on top of 3d view so it covers the plane and looks exactly the same as the plane.

My questions : How to get 2d screen size and position of a 3d plane ? Which camera type and setings to use to get 1:1 ratio between 2d and 3d? Which camera settings to use so the plane.rotationX looks the same as movieClip_mc.rotationX ?

Thanks
