The new Shader Graph, which is designed to work with the Scriptable Render Loop, enables you to build shaders visually. Instead of hand-writing code, you can create and connect nodes in a graph network with previews at every step to help you design and debug your shaders.
How to get your hands on SRP and the Shader Graph
In the next iterations of the beta, we will integrate these elements in a friendly user workflow for creating and using projects. But if you can’t wait to try them out, we made a simple sample that uses SRP, built on the Lightweight pipeline, and also includes the Shader Graph tool.
To get started, download the sample project, open it with Unity 2018.1 beta, and start exploring!
