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.

Summary

In this chapter, we’ve discussed geometry shaders.

First, we talked about the base principles behind geometry shaders – we saw what they are, how they work, and also why they can be limited or risky to use. In particular, we focused on the case of Apple devices, which are now discontinuing the support for this kind of shader, thus requiring us to think twice before using them if we need full cross-platform compatibility.

We then studied a classical geometry shader application, which is rendering a wireframe version of our meshes. In just a few dozen lines, we were able to code a URP unlit shader script that highlights the geometry of our 3D models by drawing the edges of each triangle, which even works in-game, at runtime.

We are now nearing the end of this book, and we have seen a lot of examples that have taught us various tricks about modern Unity shaders and the new URP pipeline. To wrap all of this up, our next and final chapter will examine one...
