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.

Chapter 2. Surface Shaders and Texture Mapping

In this chapter, we will explore Surface Shaders. We will start from a very simple matte material and end with holographic projections and advanced terrains blending. We can also use textures to animate, blend, and drive any other property that we want. In this chapter, you will learn about the following methods:

  • Diffuse shading

  • Using packed arrays

  • Adding a texture to a shader

  • Scrolling textures by modifying UV values

  • Normal mapping

  • Creating a transparent material

  • Creating a Holographic Shader

  • Packing and blending textures

  • Creating a circle around your terrain
