Creating Shaders with Shader Graph
Now that we know how Shaders work and the existing Shaders in URP, we have a basic notion of when it is necessary to create a custom Shader and when it is not necessary. In case you really need to create one, this section will cover the basics of effects creation with Shader Graph, a tool to create effects using a visual node-based editor, being an easy tool to use when you are not used to coding.
In this section, we will discuss the following concepts of the Shader Graph:
- Creating our first Shader Graph
- Using Textures
- Combining Textures
- Applying Transparency
Let's start seeing how we can create and use a Shader Graph.
Creating our first Shader Graph asset
Shader Graph is a tool that allows us to create custom effects using a node-based system. An effect in Shader Graph can look like the following screenshot, where you can see the nodes needed to create a hologram effect:
