What is the Master Stack in Shader Graph?

The Master Stack in Shader Graph refers specifically to the list of end nodes for vertex and fragment shading, serving as the endpoint for the graph. This concept is crucial because it represents the culmination of all the operations you perform in your shader graph, allowing you to define how input data is transformed and how the final output will look. It acts as an essential part of the workflow in Shader Graph, ensuring that all calculations and modifications you've applied throughout the graph culminate in the final shading output.

Understanding the Master Stack is vital for effectively utilizing Shader Graph, as it helps to visualize how shaders are composed. When you create a shader, it is this endpoint that dictates how the shader interprets the data passed through it, allowing for control over various effects, lighting calculations, and material properties. Recognizing this structure aids in troubleshooting and refining shaders, ensuring they operate as intended within a Unity project.
