Network View tab
The options on this tab control the display when the network editor is set to view the network as graphical tiles.
Grid and Snapping tab
|Show Operator Names|
Controls whether the names of nodes are displayed in the network editor. You can also press N to show or hide names.
|Display Network Overview|
When this option is turned on, a little window appears in the bottom-left corner of the network editor. It lets you determine where you are relative to the rest of your network. You can also pan around your network by dragging the white box as well as zoom in and out using the . You can also press O to show or hide the overview.
|Display Color Palette|
When this option is turned on, a small color palette appears in the bottom-left corner of the network editor which allows you to change the color of nodes and network boxes. To use it, select some nodes and/or network boxes, then click on the color you want them to be in the color palette.
The overview and color editor cannot be turned on at the same time because they both occupy the same space in the network editor (bottom-left corner).
Allows you to choose the shape of the wires that link the nodes together. You can also press S to toggle between the four options: Right Angles, Straight, Rounded, and Bezier.
Allows you to choose the display of the grid.
|Snap to Grid|
Choose which corner (or the center) of the tile snaps to the grid.
The amount of horizontal and vertical space between grid lines. Press on the square between the horizontal and vertical fields to get a value ladder that changes both at once.
How close to the grid the tile must be before it snaps.
|Snap to Related Tiles|
If this checkbox is turned on, a dropped node will automatically snap to line up with its parents and siblings.
|Horizontal/Vertical Snap Gravity|
The snapping distance for snapping to related tiles. The lower this value is the closer the node has to be to the center of the parent or sibling node to snap.
The options on this tab let you display an image as a background for the operator tiles.
|Display background image|
Turns on display of the background image.
|Pan and zoom background|
When this option is on, panning and zooming the network view also pans and zooms the image. When this option is off, the background stays fixed as you pan and zoom.
The path of the image file to use. Click the + icon to show a file chooser.
The display quality of the background. Higher numbers give greater fidelity to the original image, but may slow down redraw of the network view.
Houdini can show you extra information about how your node network is constructed inside the network editor. In particular, it shows 'dependencies,' which mean that a particular node either has a reference to or in some way depends on the contents or output of another node.
One easy way to create a dependency is to drag one node into the “Look At” parameter of another. Dependencies also occur when one node is referenced in an expression of another node.
|Show Local Dependency Links|
Displays dependency wires. Dependency wires originate from the right side of a node and connect to the left side of the node that depends on it. In the following example, geo2 depends on geo1.
|Show Influence on Subnet Contents|
If this option is turned on, the network editor will draw a wire from the right side of a node to the left side of a subnetwork node if something inside the subnetwork depends on that node. In the following example, something inside of subnet1 is dependent on geo1.
|Show Dependency on Subnet Contents|
If this option is turned on, the network editorr will draw a wire from the left side of a subnetwork node to the right side of a node if the node depends on something inside the subnetwork. In the following example geo3 depends on something inside subnet1.
|Show References to External Nodes|
If a node depends on another node outside the current network, the network editor draws a pink “aura” around the top half of the node.
Also, if one of a network’s contents (e.g., the nodes inside a subnetwork) depend on a node outside the network, the network editor draws a dotted “half-tone” pink aura around the top of that network’s node.
|Show References from External Nodes|
If a node depends on another node outside the current network, draw a green “aura” around the bottom half of the node.
It is possible to bot be depended on as well as depend on other nodes, which is why the auras only cover half of the nodes.
|Show Links between Bones and IK Affectors|
Bones do not have explicit dependencies on their IK end and twist affectors, but the IK affectors matter to a chain of bones. If this option is turned on, a dark pink wire will be drawn from the right side of the IK affectors to the left side of the bones they affect.
|Only Show Links and Auras for Selected Nodes|
If this option is turned on, dependency links and auras will be invisible except when a node is selected. When it is selected, all dependency connections coming in to and going out of that selected node, as well as any auras will be displayed.
|Dependency Link Style|
Allows you to choose the shape of the wires that link the dependencies.
List View tab
The options on this tab control the display when the network editor is set to view the network as a list.
Each type of network has its own separate list of visible columns. This drop-down menu shows the columns in the Available Columns menu.
Displays the flags and parameters you can access in the list view for the network type in the Visible Columns menu. You can select and deselect the columns to turn the display on and off. If the column is selected it will appear in the list view.
The order the nodes are placed in.
|Show implicit operators|
Normally, the operator list does not include extra operations that were not created as a direct result of user actions. When this option is on, these types of operators are shown in the list. This may help you better understand how the network works for the purposes of debugging.
|Show Filter Buttons|
On the left hand side of the tree view are several buttons that let you filter the view by the type of node you are interested in. You can hide these buttons by turning off this checkbox.
You can on each of these buttons to filter, and ⇧ Shift + to add to your filter, for example to show both particle and geometry nodes.
Whether to display the flags and parameters beside the list view. This can also be toggled in the list view, with the button on the top of the left-hand toolbar.
This tab contains options common to both the graphical tile view and the list view.
|Show Operator Parameters|
If this option is turned on, the embedded parameter viewer will be displayed in the top-right corner of the network editor. This is useful if you are doing a lot of network editor operations and the network editor pane is maximized. You can also press P to show or hide parameters.
|Show Group List|
If this option is turned on, the group list will be displayed in the top-right corner of the network editor. You can also press X to show or hide the group list.
|Show Operator Tree|
If this option is turned on, the operator tree will be displayed on the left side of the network editor. This is useful for navigating around your entire hip file. You can also press W to show or hide the operator tree.
The network editor can change the color of node names, when the node has a special feature, which lets you highlight various aspects of nodes. For example, nodes with comments on them have blue names by default.
