This recipe will show you how to improve the believability of your scene using viewport filters. These filters allow a nice variety of post process effects to be applied within the viewport. This just means you can add some nice qualities to your view that are typically only seen when you render out the view in other software packages, which takes longer.
Once you have lit a scene and enabled shadows, you can apply Ambient Occlusion, Cavity Ambient Occlusion, Depth of Field, and Tonemapper filters to further improve the dynamics of your scene. For this recipe you can follow along using the Interior Demo.mud
file that is present in the code files of this book, or you can set up your own scene.
If you are using the example that comes with the code assets of the book, then the viewport filters are turned on to begin with. Go ahead and turn these off before starting this recipe. Your scene should look like the following screenshot:
