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.

Screen Effect Shaders

Our journey through the world of modern Unity shaders is almost over, and we’ve looked at quite a number of examples. In the past few chapters, we explored a gallery of 2D and 3D shaders, and we learned several handy tricks for boosting our visuals and creating easy-to-tweak effects on our sprites and meshes.

In this final chapter, we’ll discuss one last common type of shader – the fullscreen effect shader. These are global filters applied to the entire render image that make it possible to make our own custom postprocessing effects and improve the overall atmosphere of the scene.

Still, if you’ve ever lurked around the Unity forums and the shader-related threads, you’ve probably seen how the arrival of URP has sadly complicated things a little for screen effects... so we’ll definitely have to take a moment to talk about the required setup for using fullscreen shaders in URP.

In this last chapter, we’ll...
