In Shader Graph, what items are listed in the Blackboard?

In Shader Graph, the Blackboard serves as a central area where users can define and manage various aspects of their shaders. The items listed in the Blackboard enable users to create customizable shaders by allowing them to configure specific parameters directly within the material. These inputs can include colors, floats, vectors, and other data types that are essential for adjusting the appearance and behavior of the shader in real time.

By having these input nodes readily accessible in the Blackboard, users can efficiently modify properties and see the results immediately, fostering a more intuitive and interactive design process. This functionality supports the creation of more versatile and reusable shaders, as users can adjust inputs without needing to dive deeper into the shader's internal logic.

The other options do not align with the primary purpose of the Blackboard in Shader Graph. While visual representations of the final output are important, they are not what is contained within the Blackboard itself. Similarly, connections between shader components and the inclusion of textures and sounds pertain to other aspects of shader design but are not part of the purpose of the Blackboard.
