Hey Mark,
There are a few ways to do this. Here's the first way that comes to mind:
just create a hidden text knob in your group called something like
'light_node_cache' with a value of 'my_light_node'. This will be your node
name's cache; you'll need to set its value to the new node name each time
the user changes it. Then you can do something like:
cached_n_name = n['light_node_cache'].value()
L = nuke.toNode(cached_n_name)
L.setName(new)
L_name = L.name() # get the node's name in case there were any collisions
n['light_node_cache'].setValue(L_name)
# If there were collisions...
if L_name != new:
n['lightName'].setValue(L_name)
Again, not in front of nuke so I may have made typos, but that should get
you going!
Cheers,
Ean
