There is no limit to the number of nodes you can create and connect to one another, and you can make as many or as few parameter adjustments as you like within each node. The following procedures describe the ways you can add nodes to the node graph as you build each grade’s node tree.
Adding Nodes
The simplest thing you can do to add to the complexity of a node tree is to add additional nodes, in order to add more adjustments to the current grade. You can add nodes so that they’re automatically attached to nodes that are already in the node tree, for immediate adjustment, or you can add unattached nodes to empty areas of the node tree in preparation for assembling a particularly complicated and specific node tree to accomplish a difficult task.
— To add any kind of node to the node graph using the mouse: Right-click any node in the node tree, and choose the type of node you want to add from the Add Node submenu of the contextual menu.
— To add a disconnected node to the node graph: Right-click anywhere within the node graph’s background, then choose Add Node > Corrector from the contextual menu. Disconnected nodes have no effect on a node tree until they’re connected.
— To add a serial node after the currently selected node: Press Option-S key, choose Color > Nodes > Add Serial from the menu.
— To append a serial node to the very end of the node tree: Press Option-K, choose Color > Nodes > Append Node from the menu.
— To add a serial node before the currently selected node: Press Shift-S, or choose Color > Nodes > Add Before Current.
— To add nodes in parallel to the currently selected node: Press Option-P, choose Color > Nodes > Add Parallel from the menu.
— To layer nodes with the currently selected node: Press Option-L, choose Color > Nodes > Add Layer from the menu.
— To add an outside node to the currently selected node: Press Option-O, choose Color > Nodes > Add Outside Node from the menu.
Adding Nodes with Windows Turned On
There are also dedicated commands for adding serial nodes with Circular/Linear/Polygon/Curve windows automatically turned on, for convenience.
