Unity 5.x Shaders and Effects Cookbook

By: Alan Zucconi

Overview of this book

Since their introduction to Unity, Shaders have been notoriously difficult to understand and implement in games: complex mathematics have always stood in the way of creating your own Shaders and attaining that level of realism you crave. With Shaders, you can transform your game into a highly polished, refined product with Unity’s post-processing effects. Unity Shaders and Effects Cookbook is the first of its kind to bring you the secrets of creating Shaders for Unity3D—guiding you through the process of understanding vectors, how lighting is constructed with them, and also how textures are used to create complex effects without the heavy math. We’ll start with essential lighting and finishing up by creating stunning screen Effects just like those in high quality 3D and mobile games. You’ll discover techniques including normal mapping, image-based lighting, and how to animate your models inside a Shader. We’ll explore the secrets behind some of the most powerful techniques, such as physically based rendering! With Unity Shaders and Effects Cookbook, what seems like a dark art today will be second nature by tomorrow.

About the Authors


One of the most impressive aspects of learning to write shaders is the process of creating your own screen effects, also known as post effects. With these screen effects, we can create stunning real-time images with Bloom, Motion Blur, HDR effects, and so on. Most modern games out in the market today make heavy use of these Screen effects for their depth of field effects, bloom effects, and even color correction effects.

Throughout this chapter, you will learn how to build up the script system that gives us the control to create these screen effects. We will cover Render Textures, what the depth buffer is, and how to create effects that give you Photoshop-like control over the final rendered image of your game. By utilizing screen effects for your games, you not only round out your shader writing knowledge, but you will also have the power to create your own incredible real-time renders with Unity.
