Hello,
I'm trying to make "presets" from a selection of nodes contained in a
backdrop node.
The presets selection will be a dropdown menu attached to the backdrop.
My idea is to
1. ('save preset')export all the knobs values from a nodes selection to a
.nk file probably the nuke. (e: nuke.nodeCopy("c:/temp.txt"))
2. ('load preset')get and paste all values from that file to the exactly
same nodes selection
I there an easy way/function to get these knob values and replace the ones
existing in the dag?
In the next example, if u double click on the backdrop node, what function
can I put in the load button?

nuke.thisNode().knobs()\['Load']\nPresets=sorted(os.listdir(\"C:/Presets\"))\na=\[]\nfor
i in Presets:\n
a.append(i.split('_')\[1].strip('.nk'))\n\npulldown.setValues(a)\n"}
addUserKnob {22 LoadPreset l "Load Preset" -STARTLINE}
addUserKnob {26 ""}
addUserKnob {22 Save -STARTLINE T "#function to find all nodes inside the
