Overview of this book

Since their introduction to Unity, shaders have been seen as notoriously difficult to understand and implement in games. Complex mathematics has always stood in the way of creating your own shaders and attaining the level of realism you crave. Unity 2018 Shaders and Effects Cookbook changes that by giving you a recipe-based guide to creating shaders using Unity. It will show you everything you need to know about vectors, how lighting is constructed with them, and how textures are used to create complex effects without the heavy math. This book starts by teaching you how to use shaders without writing code with the post-processing stack. Then, you’ll learn how to write shaders from scratch, build up essential lighting, and finish by creating stunning screen effects just like those in high-quality 3D and mobile games. You'll discover techniques, such as normal mapping, image-based lighting, and animating your models inside a shader. We'll explore how to use physically based rendering to treat light the way it behaves in the real world. At the end, we’ll even look at Unity 2018’s new Shader Graph system. With this book, what seems like a dark art today will be second nature by tomorrow.

Extruding your models

One of the biggest problems in games is repetition. Creating new content is a time-consuming task, and when you have to face thousands of enemies, chances are that they will all look the same. A relatively cheap technique to add variation to your models is using a shader that alters its basic geometry. This recipe will show you a technique called normal extrusion, which can be used to create a chubbier or skinnier version of a model, as shown in the following screenshot of a soldier from the Unity camp demo:

For ease of use, I have provided a prefab of the solider in the example code for this book under the Chapter 6 | Prefabs folder.
