Connecting Nodes
 
 
 

The relationship between objects is referred to as a parent-to-child relationship. When you add certain objects to the scene, a parent-to-child relationship is created automatically. For example, when you add a surface in Action, it is automatically parented by an axis. You can also manually connect nodes to create and change relationships between objects. You can create complex animations where movements applied to a parent node are passed down to all connecting child objects.

You can use Parent mode to create and change the parent-to-child relationship between nodes. Alternatively, if Auto Parent is enabled in the Setup menu (of Action, Batch, and Modular Keyer), you can also use Move mode to parent nodes.

To connect nodes:

  1. Do one of the following:
    • In Parent or Move mode, click and drag the cursor from one node to another.
      NoteIn the Setup menu of Action, Batch, and Modular Keyer, the Auto Parent option must be enabled if you are in Move mode.

    • In Move mode, press Shift and drag one node to another so that they touch.

    A line is drawn connecting the nodes. The direction of the arrow indicates the parent-to-child relationship. Any changes made to an object will be passed down to all connecting child objects.

    In the following Action scene-based schematic, the selected node (axis3) is the parent of shadow1. Changes made to axis3 are passed down to its child node—shadow1.

    NoteIn scene-based schematics, an object can be manipulated directly in the scene or through its associated menu.

    (a) Axis of shadow corresponds to axis3 node (b) Shadow corresponds to shadow1 node (c)  axis3—the parent of shadow1—is used to change the shadow’s position

To insert a node between connected nodes:

  1. Press Shift, drag the node on top of the link, and then release the cursor.
NoteIn the flow graph environments of the Modular Keyer and Batch, there are additional ways to connect nodes with input sockets. For Batch, see Connecting Clips and Nodes. For the Modular Keyer, see Adding Nodes to the Pipeline.
