and i have questions, is this a pre render in game engine and only playing like a movie or real time animation in game render. If this is real time game engine can i do something like that in Unity. Take my main character from the game, make some animations and create background to main menu ?
Like you say - animation with background. For simple main menu you can put all menu things on other layer and when press Esc - active menu (with second camera). Use DontDestroyOnLoad to keep menu for next scene. For complex menu better use other scene than hiden layer.
