Defaults

Python Script1/13/2025

Many of the factory defaults for Nuke don't make a lot of sense. These alternative defaults add convenient labels, set default channels to rgba' instead of all, BBox to B', motion blur to centered', among other. Any one of them can be disabled by commenting the line out with a # or by simply deleting the line. Installation Copy the lines into a file called menu.py into a folder that is watched by nuke at startup. You can find these folders by running nuke.pluginPath()' inside the nuke script editor.
