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

Chapter 9. Gameplay and Screen Effects

When it comes to creating believable and immersive games, material design is not the only aspect that we need to take into account. The overall feeling can be altered using screen effects. This is very common in movies, for instance, when colors are corrected in the post-production phase. You can implement these techniques in your games too, using the knowledge from Chapter 8, Screen Effects with Unity Render Texture. Two interesting effects are presented in this chapter; you can, however, adapt them to fit your needs and create your very own screen effect.

In this chapter, you will learn the following recipes:

  • Creating an old movie screen effect

  • Creating a night vision screen effect
