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.

Stepping up with the URP render pipeline

The URP is one of the two new SRP templates. It is meant to be highly customizable via a gallery of tools, scalable to ensure your projects are cross-platform between mobiles and desktops, and all-around a more optimized rendering solution than the built-in render pipeline. However, it is not installed by default in all your Unity projects, and we need a few preliminary steps to get a project URP-ready.

So, in the following sections, we will discuss how URP helps foster creativity and support multiple platforms. Then, we will examine the new node-based visual editors it offers, and finally, we will have a look at how to get and set up the URP in a project (both a new and an existing one).

A powerful pipeline for all creators

The URP is gradually becoming the standard for most Unity projects because of its wide variety of applications, its ease of use, and its scalability. Initially called the Light-Weight Render Pipeline (LWRP), it...
