Overview of this book

Do you really know all the ins-and-outs of Unity shaders? It’s time to step up your Unity game and dive into the new URP render pipeline, the Shader Graph tool, and advanced shading techniques to bring out the beauty of your 2D/3D game projects! Become a Unity Shaders Guru is here to help you transition from the built-in render pipeline to the SRP pipelines and learn the latest shading tools. With it, you’ll dive deeper into Unity shaders by understanding the essential concepts through practical examples. First, you’ll discover how to create a simple shading model in the Unity built-in render pipeline, and then in the Unity URP render pipeline and Shader Graph while learning about the practical applications of both. You’ll explore common game shader techniques, ranging from interior mapping to adding neon outlines on a sprite or simulating the wobble of a fish. You’ll also learn about alternative rendering techniques, like Ray Marching. By the end of this book, you’ll have learned to create a wide variety of 2D and 3D shaders with Unity’s URP pipeline (both in HLSL code and with the Shader Graph tool), and be well-versed with some optimization tricks to make your games friendly for low-tier devices as well.

What is the Shader Graph?

To begin with, let’s do a quick review of what the Shader Graph is exactly.

In the next sections, we will see what this tool is useful for and who it can benefit, how we can add it to a Unity project, and how to navigate its interface.

A tool for everyone…or not

As we have mentioned previously in Chapter 2, the Shader Graph is a new node-based shader creation tool Unity added to the engine in 2017, when they added the SRP pipelines. This visual tool was made with multiple goals in mind:

  • Ease-of-use: First and foremost, the Shader Graph is meant to be beginner-friendly – in particular, it simplifies the process to allow artists and non-coders from the team to actively participate in the development of the graphics. But it can even be useful for shader developers too because it usually makes prototyping more straightforward and more pleasant.
  • Instant feedback: Another key characteristic of the Shader Graph is that it...
