Here is a small scene.Just play it on pc using a utgame so that you can see the default robot character.In the level you go to the trigger and when its touched>the camera is detached from the player and another blended one is going to start making a loop animation in a circle for ever.>a cube with a second trigger will go down and when you touch the trigger the camera will blend back to your players camera.
Its not perfect as when the camera returns, it is not in the exact position it was before, but i think that can be fixed.Still, the scene and cameras are seamless.
Not sure if this is what you are looking for.
