Hi Nathan,
attached is a Nuke script that contains a group node with a python button
and a sticky-note that contains the Python script. Just save it in your
Nuke path.
This seems to work a little bit better than my full script, but it still
crashes a lot. It crashes for example if I set it above 10 and also often
when I set it back to 1. In my full script I have a couple of more loops
that does other things (set inputs, moves node around to x,y pos). I'm
pretty new to Python so I would very much appreciate a nod in the right
direction on this (the only reason I got this far is because of this list).
Thanks.
