This is a simple video of my initial implementation of 3d rendered menus using Xna and SunBurn engine.
The purple rendering after the SplashScreens is my Asynchronous loading screen which isn't rendering anything for now :p
Each menu screen is rendered to a RenderTarget2D which gets updated only when the UI needs to be redrawn; otherwise, it uses the cached texture.
In the next video, I'll add some scenery behind the menu to improve a bit the visuals :)
