# Inspecting Graph State Variables

The value of a project-wide Graph State Variable can be inspected through the variables section of the main menu bar. The value of a local Graph State Variable can be inspected in the Parameters tab. To do this:

| 1. | Set the edit flag on the node at which you’d like to view the Graph State Variables.

| 2. | Set the view flag on whichever downstream node you’d like to produce scene data from.

Note: If you have a VariableSet node that does not lie between the edited and viewed nodes, it is not a contributing node and has no effect.

| 3. | In the Parameters tab, click the Graph State Variables button () to the right of the node name.

A list of variables and their current values appears in the pop-up menu. The values of Graph State Variables cannot be changed in the widget; it is read-only.

When the Graph State Variables menu is shown while a node is currently viewed, and the edited node is part of the active node graph, the menu displays Graph State Variables that are seen in the portion of the node graph between the currently viewed node and the respective edited node.

When the Graph State Variables menu is shown while no node is currently viewed, or if the edited node is not part of the active node graph, the menu displays a label with red text to indicate that the edited node is not part of the currently active node graph and that Graph State Variables are not available.

To see the effect of VariableSwitch and VariableEnabledGroup nodes, open the Node Graph tab and choose Edit > Dim Nodes Not Contributing to Viewed Node from the tab’s menu, or press Alt+. (period). When this option is turned on, nodes in the Node Graph tab that are not part of the currently active node graph portion are drawn in a dimmed appearance. This is determined by taking into account the active graph state and possible VariableSwitch and Switch nodes that may be a part of the node graph.
