Book Description
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.

What you will learn
Understand physically based rendering to fit the aesthetic of your game
Write shaders from scratch in ShaderLab and HLSL/Cg
Combine shader programming with interactive scripts to add life to your materials
Design efficient shaders for mobile platforms without sacrificing their realism
Use state-of-the-art techniques, such as volumetric explosions and fur shading
Master the math and algorithms behind the most used lighting models
Understand how shader models have evolved and how you can create your own

Who This Book Is For
Unity Shaders and Effects Cookbook is for developers who want to create their first shaders in Unity 2018 or wish to take their game to a whole new level by adding professional post-processing effects. A solid understanding of Unity is required to get the most from this book.
