The Node Editor presents an editable schematic of the dependency graph, displaying nodes and the connections between their attributes. It allows you to view, modify and create new node connections. You can access the Node Editor from the Windows menu. (Window > Node Editor).
The connected mode shows the input and output master ports, as well as any connected attributes. These attributes have their own ports, which are displayed as small circles. The icon also denotes that you are in the connected mode.
The full mode shows the input and output master ports, as well as primary node attributes. The set of primary attributes for a given node is based on the properties of the attributes such as whether they are keyable or dynamic. The icon also denotes that you are in the full mode.
Input attributes are displayed on the left side of a node in full mode. Output attributes are displayed on the right side. To expand a node's attribute list, click the located next to the attribute. If an attribute can be connected as either an input or an output, a port is available on both the left and right sides of the node. Use the shortcut + click on the icon of a compound attribute to expand all layers of its children. Alternatively, you can use the same shortcut on the icon of a compound attribute to collapse all layers of its children.
You can select the Show All Attributes option from the node marking menus (or the hotkey 4) to temporarily replace the full mode for a node with a listing of all of the attributes. The displaying of all of its attributes is only valid for this draw instance. If you regraph the node, or if you change the view mode of the node, you must re-select this option to see all of its attributes again. See for more information about the Node Editor marking menus.
You can change the view mode for multiple nodes in one step by selecting the nodes and selecting the desired mode icon in the toolbar. You can also do the same via the menu options (Edit > Simple Mode, Connected Mode, Full Mode) or using the 1, 2, 3 hotkeys. See and for more information.
