You can also set the `nuke.DO_NOT_WRITE` flag on knobs that you don't want to
be written to the script; you'll need to do this every time an instance of that
node is created via a callback or something, since the DO_NOT_WRITE flag
prevents itself from being written as well. Preventing an entire node from
being written is probably a bad idea, because it could potentially screw up the
structure of the node graph.

Subject: Re: [Nuke-python] How to prevent certain nodes from being saved
withscript?
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^)

Hi Rich,
lame answer, but callbacks seem to be the way to go here :-)
At least I cannot think of another way to achieve this besides using
callbacks.
But the nodes would be deleted then each time one hits ctrl+s ?!
Hahaha! Yes, that would be a rather annoying side effect! ;^) And, since I
am the "king of excessive versioning”, I would be affected the most! LOL
I guess I was looking for a way to make the nodes “invisible” to the script
save routine. To ignore them, if you will. That could cause other, unexpected
problems, I suppose. I guess I’ll have to think about some other options… Hmm...
Thanks.
Rich
sth like
def deleteCustomNode()
customNodes = nuke.allNodes('customClass')
for node in customNodes:
nuke.delete(node)
addOnSCriptSave(deleteCustomNode)
Couldnt you stuff the function back into the knob instead ?
I dont know what the idea behind all this is, but maybe that could work
too...
Cheers

Hi,
I have some nodes I am creating that I don’t want the user to save with
the script. On their hidden “knobChanged” knobs, they reference an
in-memory-only function that only gets loaded when the nodes are created. So,
if they are saved with the script, the function is not found when they are
restored and the custom knobs do nothing. So, I would like to prevent the nodes
from being saved with the script. That way, the user will have to create new
nodes the next time; the function will be referenced and loaded into memory and
all will be well… What’s the best way to prevent a node from being saved?
Should I use the onScriptSave callback? Or, is there a better way?
Thanks,
Rich
