Several node types, including surface nodes, particle nodes, dynamics nodes, compositing nodes, and channel nodes, have a bypass flag that turns the effect of the node off, effectively passing its input directly through to its output. This lets you temporarily turn off expensive operations, flip back and forth to see the effect of a node, and try out variations.
In surface networks, the bypass flag is the yellow flag at the left end of the node. When a node is bypassed, it has a striped background to make it more visually apparent.
See node flags for more information.
You can color the nodes in the network editor. This lets you annotate different areas, functions, and/or classes of nodes in the view using color. For example, in a shading network you could color all the lighting model VOPs yellow to make them easier to find at a glance.
Press C to show the color palette.
Select the node(s) you want to color.
Click a color in the palette.
Press C again to hide the palette.
Sticky notes can be created in the network editor. This will create a yellow text box where you can comment on nodes or networks.
|Create a sticky note|
Press Ctrl + P in the network editor.
Click the text box and type.
|Move a sticky note|
Drag the bar across the top.
|Resize a sticky note|
Drag from one of the corners.
|Minimize a sticky note|
Click the minimize button at the top right of the note.
|Remove a sticky note|
Click the X button at the top right of the note.
Network boxes let you group nodes together visually. This is useful when you can’t or don’t want to collapse the nodes into a subnetwork but you want to distinguish them from other nodes. For example you could group the nodes representing different limbs of a character rig in different boxes.
|Create a network box|
You can embed network boxes inside other network boxes.
|Add or remove a node to/from a network box|
|Move or resize a network box|
|Remove a network box|
|Collapse a box to a stamp|
|Assign colors to network boxes|
Subnetworks let you encapsulate multiple nodes inside a single node, streamlining your network visually and conceptually. Note that putting nodes inside a subnetwork changes their path.
The subnetwork node can have up to four inputs, which are passed down to special nodes inside the subnetwork.
|Create an empty subnet|
|Create a subnetwork from existing nodes|
|Move one or more nodes inside a subnetwork|
|Connect the subnet’s inputs to node inputs inside the subnet|
|Choose the subnet’s output|
|Label the subnet’s inputs|
|Edit a node’s comment field|
|Display a node’s comment|
In the network editor, hold on the node.
