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.

Exploring the Unity Compute Shaders and Procedural Drawing

Up until now, we have focused mainly on the most common application of shaders in video games: the rendering of objects in 3D scenes. We have seen various tools and techniques and studied complex shading tricks, but they all aimed at visualizing some geometry on our 2D screen.

However, shader scripting is a very interesting type of development that can be used to solve other problems, too. For example, because, at its core, it is about writing low-level code to run in parallel for many data points, the art of shader creation can be transposed to another fascinating topic: the efficient processing of expensive computational tasks.

In Unity, it is possible to greatly increase the speed of some large calculations by taking advantage of the power of shaders and offloading the work from the CPU to the GPU, using compute shaders. This, in turn, can lead to delightful advanced techniques in the field of procedural drawing.
