Control Nodes do not necessarily have to exist within Subcompositions. You can create Control Nodes at the parent/root level of a Composition. Doing this creates a "Global" Control Node.

Global Control Nodes in Compositions

In order to create a Global Control Node in a Compositon, a Control Node must be created at the parent/root level (the highest point in the Composition Tree). For example, a Color Control Node created a the parent/root level of your Composition can serve as a global color selector. Just make sure the color property of all your colored elements within your Composition are connected to this Color Control Node. 

In the example below, we are at the parent/root level of the Composition. As you can see in the Data Interface and Control Panel, the "global color selector" is set to blue. If we update it to red, the overlays primary color will change to, you guessed it, red.

To connect Composition elements to Global Control Nodes, make sure to choose the "Root / Control Node" option in the Node Link Browser.

Global Control Nodes in Control Applications

A Global Control Node appears within the "Global Data" overlay layer in your Control Application. In the example below, you can see that we have the "Global Data" layer selected and the Global Color Control Node appears in the Overlay Editor Panel.

Note

Dig into the Composition of various Marketplace Themes to see the different types of Global Control Nodes we have created. Open those themes up into Studio and see how those Global Control Nodes appear in the "Global Data" overlay layer.
