Adding Saved Settings from the File System
Saved settings in your File system can also be used to create new nodes by dragging the .setting file
into the Node Editor from a standard file browser. Once dropped, that setting turns into a new node.
TIP: If you drop a setting directly onto a connection line, the new node will be inserted onto
that connection.
Node Modes Including Disable and Lock
Right-clicking one or more nodes and opening the contextual menu reveals a series of commands in
the Modes submenu, some with accompanying keyboard shortcuts, that let you set control visibility,
disable, lock, update, and cache nodes.
– Show Controls: Sets whether that node reveals its parameters in the Inspector when it’s selected
and whether its onscreen controls appear in viewers. On by default.
– Pass Through: (Command-P) Identical to the toggle switch in the Inspector that turns nodes off
and on. Disabled nodes are ignored as image data is passed from the next previous upstream
node to the next downstream node. On by default.
– Locked: (Command-L) Identical to the lock button in the Inspector that prevents a node from being
edited in the Inspector. Off by default.
– Update: (Command-U) On by default. While this option is enabled, all changes to the node will
cause it to re-render. When Update is disabled, you can still change the node’s parameters, but
those changes will not process or update the image until Update is re-enabled. While disabled,
the last processed image for that node will be displayed as a freeze frame. One example of when
this is useful is when you have a large or processor-intensive composition (such as a particularly
intense particle system), and disabling this option temporarily will let you quickly make several
quick parameter adjustments to different nodes without forcing you to wait for the node tree to
re-render after every adjustment. Another example of when this is useful is when you want to
quickly see the effect of animated downstream nodes while keeping upstream nodes that are too
processor-intensive to play in real time from rendering additional frames.
– Force Cache: When enabled, this node’s output for the current frame has an extremely high cache
priority, essentially forcing it to stay cached in memory. Off by default.
Toggling any one of these node modes displays a badge within that node indicating its state.
Node Editor Options
Right-clicking in an empty area of the Node Editor will bring up the contextual menu and the Options
submenu. The Options submenu contains several choices that can be used to customize how the
Node Editor looks and behaves.
– Pipes Always Visible: Enabling this option causes a connection to cross over a node instead of
beneath it, sometimes making it easier to follow the connection’s path.
– Show Hidden Connections: When enabled, the Inspector option to Hide Incoming Connections in
every node is overridden and all connections are displayed in the Node Editor.
– Aspect Correct Tile Pictures: Aspect Correct Tile Pictures forces the display of thumbnails to be
aspect corrected, which is slower but visually more accurate. This option is enabled by default.
