External Structure of Nodes



You can grasp the overall role of a node and the direction of data input/output at a glance.


  • Node

    • This area displays the node's core information (type, title, content).

  • Pin

    • These are connection points located on the left and right sides of a node, used for exchanging data.

      • In-Pin : Located on the left side of a node, this is the point where data is received from other nodes or external systems.

      • Out-Pin : Located on the right side of a node, this is where processed data is transmitted to the next node or system.

      • Function-Pin : Can be configured for function features and utilized within a Python Node.

    • Each connector is connected to other nodes via edges to exchange data.



Internal Structure of Nodes



  • Double-clicking a node on the canvas will take you to the Node Editor for detailed settings for the node.

  • Except for the mandatory Start Node and End Node, most nodes are broadly divided into three parts: Input, Settings, and Output.





  • Input Section

    • You can see what data is input through the In-Pin.

  • Edit Section

    • This section configures the node's core functionality. The input varies depending on the node type.

  • Output

    • Defines what data the node outputs through the Out-Pin after completing its task.
