Collection of utilities for manipulating Nuke’s NodeGraph

Installation

Easy install

Download the whole .zip file of the project and uncompress it somewhere, for example C:\Users\my_user\.nuke\node_graph_utils.
In your init.py (see https://learn.foundry.com/nuke/developers/131/pythondevguide/startup.html for more info on init.py), add the following line:

nuke.pluginAddPath(r'C:\Users\my_user\.nuke\node_graph_utils')

(Ensure you adjust the path to your own install path. It should point to where the provided menu.py lives.)

Custom Install

You could modify the installation to fit your needs. The simplest modification you could do is to exclude the experimental features.
To do so, locate the provided menu.py and change the line:

node_graph_utils.install_menus(icons_root=ICONS_ROOT, install_experimental_menus=True)

to

node_graph_utils.install_menus(icons_root=ICONS_ROOT, install_experimental_menus=False)

If you would like, you could also store the icons in a different location and provide the icons path to this method.

For advanced users, using the pre-made install_menus method is optional and all fucntions can be exposed manually from scratch.

Customizing keyboard shortcuts

All the menus and keyboard shortcuts are defined in the install_menus method, which lives in the package’s __init__.py file.
By default, I have mapped the shortcuts to be used along with the meta key (windows key on keyboards).
If for example you wanted to remap the “AutoBackdrop” command to Ctrl+B instead of my default Alt+B (because somehow you use nuke’s Branch command, which normally has the Alt+B shortcut).
You would locate the line where the command is added:

backdrop_menu.addCommand('AutoBackdrop', backdrops.auto_backdrop, 'alt+b', shortcutContext=2, icon='Backdrop.png')

and change the shortcut like so:

backdrop_menu.addCommand('AutoBackdrop', backdrops.auto_backdrop, 'ctrl+b', shortcutContext=2, icon='Backdrop.png')

Thanks for this Erwan, the scale UI is awesome!!

One idea/feature request on that one would be to have the ability to not scale from the bounds of the nodes but instead by their centres. That way it you select a bunch of nodes and you scale up to the left, if the right part is connected on a vertical pipe they wouldn't get out of position but the last column on the right would stay still.

Nice to have all this functionality in a single download. The Node Scaling UI is super helpful!

The houdini-like y snip is brilliant and so oddly satisfying!

On Centos 7 the entire nodegraph goes black when I invoke the scale tool. Damn, was so looking forward to this. Any idea what might be causing that?

Are you on linux as well? Such a shame cause other thatn that it works great (from what I can tell). The snipping/drawin g connections have the same issue. They do work but the DAG goes black as soon as I hold down the respective hotkey. Maybe that is a hint where to look?

Try turning on Centos Desktop Effects, Alt+Shift+F12 - this allows GL transparency to work.

Thank you very much for this, the scaling is really really nice.
