Unity Shader Graph: Node-Based Shader Authoring Overview

Unity's Shader Graph was introduced in beta with version 2018.3 and has been officially supported since 2019, providing a node-based programming approach.

Compared to vertex/fragment shaders, it still has some constraints and can feel unstable, but it enables rapid prototyping.

For simple expressions or performance-insensitive environments like PC, you can achieve surprisingly complex effects with it.
