What is Viewer Lock?

Don't you hate it when your viewer's not connected to the nodes you think it's connected to? Like when you're rotoing and you're trying to A/B between the plate and the comp, but the roto node's overlay has hijacked Nuke's focus and now you're looking at some random roto node?

Usually when I ask people this, the answer is no. But I sure do, so I made this.

Viewer Lock is a tool that allows you to lock viewer inputs to nodes, so that they're always assigned to what you think they're assigned to. I've been using this personally for a couple of years now, but I thought I'd share it in case there were people out there who also have this fairly niche problem.

Usage instructions

Press Shift+V to open the Viewer Lock panel, or, if you already have one open, to bring it to focus.

The left row of checkboxes show which inputs are in use. Uncheck them to unassign the input. The right row of checkboxes show which inputs are locked. Check them to lock the input to the node it's currently assigned to, or to uncheck them to unlock. The checkboxes at the top unassign all inputs and lock/unlock all inputs, respectively.

You can also use shortcuts:

  • Ctrl+Alt+(number) will lock the input to the selected node, or reassign a locked input to the selected node.
  • Ctrl+Shift+(number) will unlock the input and assign it to the selected node as normal.
  • Ctrl+Alt+V and Ctrl+Shift+V will lock and unlock all inputs respectively.

I haven't tested this on a Mac. If any Mac users out there download this and something's wrong, let me know so that I can either fix it or untick Mac compatibility. I also haven't tested this on anything earlier than Nuke 10, but in theory there's no reason it shouldn't be backwards compatible.

This will not work with non-commercial Nuke because of Python restrictions. :(

Installation instructions

Unzip the file and move the contents to your .nuke folder, keeping the contents of the viewerLock folder inside that folder. If you already have a file, combine it with this one.
