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.

Using the built-in render pipeline

Up until now, we have looked at Unity’s built-in or legacy render pipeline. This was a good way to learn how to make shaders in this game engine. However, this pipeline also has its share of limitations.

So, in this first section, let’s discuss the advantages and drawbacks of this pipeline, as well as how we can extend it, thanks to CommandBuffers.

A handy but limited pipeline

The built-in pipeline has several advantages:

  • The most obvious plus is that it is readily available as soon as you create a new Unity project with a basic template. It lets you get familiar with the whole toolchain of shaders, materials, and mesh renderers.
  • Since it’s been around for a long time, the built-in render pipeline is also compatible with a large number of pre-existing shaders, VFX, third-party tools, and learning resources.
  • Of course, because it is a general-purpose render pipeline, it handles most of the common use cases...
