Figure 1.22 A Read node’s properties panel
Within the Read node’s properties panel, you can set the color space and alpha pre-
multiplication of the imported files. These parameters are discussed in Chapter 2 and
Chapter 3.
If the resolution of imported footage does not match the Full Size Format setting in
the Project Settings properties panel, the footage will not “fit” the project resolution frame.
Thus it may be necessary to connect a Reformat node. For a demonstration of this, see the
section “Nuke Tutorial 1: Working with the Reformat Node” at the end of this chapter.
Connecting Nodes
You can connect nodes in an almost endless fashion in the Node Graph. Here are a few
approaches to keep in mind:
To connect two nodes, LMB+drag an unused pipe (connecting line) from one node •
and drop it on a second node. Each pipe has a specific input or output function.
Input pipes are indicated by a line and arrowhead pointing toward the node (see
Figure 1.23). Input nodes are generally labeled. The exception to this rule is a Mask
input, which takes the form of an inward-
pointing arrow stub at the right side of the
node. Output pipes are indicated by an
outward-pointing arrow stub at the bot-
tom edge of the node.
If a node is selected and a new node is cre-•
ated, the new node is automatically con-
nected to the selected node’s output.
To disconnect a node, LMB+drag the pipe •
away from the connected node. When you release the mouse button, the pipe is bro-
ken. You can also select the node that is downstream (that is, the one that receives the
input) and press Ctrl+D.
To select a node, LMB+click the node icon. To open a node’s properties panel, double-•
click the node icon. To select multiple nodes, Shift+click the node icons.
To disable a node so that it no longer influences the node network, select the node and •
press D. To enable the node, press D again.
To delete a node, select the node icon and press the Delete key.•
To rename a node, open its properties panel and enter a new name into the top cell.•
