As part of Chapter 5, Screen Space, World Space, and the Camera, I set up a simple 3D demo scene with a few effects to make the UI really stand out and shine. However, as the focus of this book it has been moved to an appendix for you to follow if you so wish.
Additionally, the appendix is also available online at http://bit.ly/UnityUIEssentials3DDemoScene.
Note
If you want to skip the scene's creation or just use the completed version to follow through, then you can download the .UnityPackage
asset for the demo scene from http://bit.ly/UIEssentialsCh5DemoScene and then just import it into your project as a Custom Package using Assets | Import package | Custom Package… in the Unity menu.
This chapter just works through a couple of 3D tips and tricks that you can use in any scene to help liven it up and work through some of the niggles of working in 3D scenes.
