Linking Channels Using the Link Menu

You can create expression links to connect channel and layer controls with other controls in various nodes. Since these controls aren’t meant to be animated, you can’t use the full range of Nuke expressions, nor can you use Python or Tcl languages. You can link controls using the Link menu next to the control on the properties panel:

1.   Click the Link menu and select Set link. An Expression dialog opens.
2.   Enter your expression in the Expression field and click OK. For more information on expressions, see Expressions.
3.   You can edit an existing link by clicking the Link menu and selecting Edit link.
4.   You can also Ctrl/Cmd+drag the Link menu to another control to create a link between the two.
5.   To remove a link, click the Link menu and select Remove link.
