Getting started with Unity's new Shader Graph Node-based Shader Creator/Editor (tutorial 6 - Getting Glow/Bloom Effect wihout Post-Processing by Inverting Fresnel...Sort Of...)
Introduction (to the Tutorial Series): I will be writing about my own experiences using Unity's new beta Shader Graph, part of its upcoming 2018 release (also in beta). The Shader Graph lets you create a variety of Unity shaders using nodes - not requiring you to write code. I will be writing about this journey over multiple posts, usually spaced about a week apart. Each post will be a short tutorial on how to use various node types to create different shader effects. And will include brief discussions on types of shaders and their uses, and later, how the Shader Graph compares with code-based shaders. I will try not to get overly technical, but will try to give you an idea of the complexity involved in shaders, from lighting to vertex and fragment manipulation. Given the nature of beta software, expect the Shader Graph (and later tutorials) to vary from earlier ones that you can now find online. Even within my tutorials there will be changes if/when the beta evolves - in...
