Just an update on this subject…
It turns out that, because I’m using a full Python path to my function call in
the hidden knobChanged knob, Nuke actually finds the function when the script
gets saved and reloaded — bonus!! So, in other words, I don’t need to do
anything at all — and it just works! 8^)
