There are currently 26 nodes at your disposal within the material editor which provide a wide range of functionality.
Nodes have input and output plugs which allow you to link nodes together. By hovering over an output plug, Left click and drag over a compatible input plug to create a link between two nodes. Note that plugs are color coded depending on the information being transferred. Only plugs with the same color can be connected together.
Each node as a Variable Name property. Each variable name is automatically generated when a node is added to the material, however it can be edited providing that no other node in the material has the same variable name. The variable name allows you to alter values within the shader via scripting giving you greater control over your materials outside of the material editor.
