Unity 2018 Shaders and Effects Cookbook - Third Edition

Implementing a glowing highlight system

Now that we have some background information on how to build shaders, let's look at a real-world example of a shader we could potentially use. When playing certain kinds of games, you may notice that, when the player faces an object they can interact with, the object may glow such as in Dontnod Entertainment's Life is Strange, The Fullbright Company‎'s Gone Home, and even in recent mobile games such as Jam City's Harry Potter Hogwarts Mystery. This is something that we can easily do in Shader Graph, which will also allow us to see a non-trivial example of Shader Graph being used.
