Overview of this book

Unreal Engine 4 is a powerful game engine, one which has seen a recent boost in widespread adoption thanks to its ease of use and the powerful rendering pipeline that it packs. Seeing as how it's relatively easy to create stunning presentations and visuals, Unreal has quickly become a strong contender in industries where this kind of software had been previously denied entry. With that in mind, this book aims to help you get the most out of Unreal Engine 4 - from creating awe-inspiring graphics to delivering optimized experiences to your users. This is possible thanks to a mixture of hands-on experience with real materials and the theory behind them. You will immediately know how to create that material that you want to display, and you'll also end up with the knowledge that will let you know how to control it. All of this will be done without losing sight of two key components of any real-time application - optimization, and efficiency. The materials that you create will be light and efficient, and they will vary depending on your target platform. You'll know which techniques can be used in any kind of device and which ones should be kept to high-end machines, giving you the confidence to tackle any material-related task that you can imagine. Hop onboard and discover how!

Using a post-process volume


In order to access the different post process effects that Unreal has in store for us, we will need to place a specific actor in our level. This actor receives the name Post Process Volume, a container in the shape of a box that specifies its area of influence.

Thankfully for us, every setting that we are going to be tweaking in this chapter can be modified using the previous actor. Having all of the post process effects grouped in one place makes our lives easier—so, let's start looking at all of the different options that we can play with!

Getting ready

I've prepared a scene for you to use as you traverse through the different recipes of this chapter—it is a very simple one, but it should help demonstrate the different post process effects that we are going to be using in the next pages. You can locate the file by navigating to the following directory inside the Unreal project we are providing: Content/UE4ShadersAndEffects/Maps/Chapter02.

The name of the scene is...
