It’s best if we briefly talk about spaces before talking about nodes.
I’ll also cover a bit of prerequisite knowledge before we dive into shaders! I won’t cover the nodes that are contained in the High Definition Render Pipeline package - I’ll only be covering those contained within the base Shader Graph package. the guy she tells you not to worry about.
I like to think of them as code’s fun cousin. Enter Shader Graph: an alternative to code shaders which uses nodes representing different functions which users can plug into each other on a visual and interactive graph. Traditionally, shaders have existed solely in code, but that’s not very approachable or accessible for artists who don’t code. Shaders are mini programs that run on the GPU, and they do things like texture mapping, lighting or coloring your objects in fancy ways, but you probably already know that if you clicked on this article. Let’s start with a quick run-down of what Shader Graph is and why it exists.
