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.

With screen effects, we can turn the mood of a certain environment from calm to scary, just by changing the look of the screen. Imagine walking into a room that is contained within a level, then the game takes over and goes into a cinematic moment. Many modern games will turn on different screen effects to change the mood of the current moment. Understanding how to create effects triggered by gameplay is next in our journey of shader writing.

In this chapter, we are going to take a look at some of the more common gameplay screen effects. You are going to learn how to change the look of the game from normal to an old movie effect, and we are going...
