Do I just run that for an update, as if I try and run it in the script Editor
it doesn't trigger the knob updateUI.
Below is the node I am attempting to get to update reliably. It WILL update but
often it's missed. It's the 'channelShuffler' node inside the VIEWER_INPUT
group.
An alternative could be to check what the viewer is attached to but I haven't
figured that one out yet.
Cheers
Howard
