Let's say, we got a game with 50 scenes onto which we transform players using the Application.LoadLevel() thing. Let's say Players can choose level using a static gui. However we have a 3D scene, which has nice and cute player-clickable islands. If we load up this scene, the player can choose an island by clicking on it, then it gets loaded using LoadLevel().
Now let's say, that a player is already ingame at an island scene. The player wants to open the 3D map in a small window without his current game terminating. Basicly we want picture in picture.
How can we load a scene in a way, that it would not terminate the already loaded one, while the new scene appears as a gui-element (like a GUI.Window or GUI.Box or something) in a new 'gui-window'.
