Multiparm (list) parameter linking

[just_bob_2nd]

Hi, I'm losing my mind over how to link subnet parameters with the ones inside of it. I've got it to read the number of parameters and make that many, but can't make it read and populate the values accordingly. Super simple example hip down below. Basically the values on the subnet controls should correspond to the values on the wrangle inside.

Thanks

Hey, you can setup a python callback script which dynamically reference the parameters from your hda to the wrangle.

Here's a quick example :

listparm_hda = kwargs["node"].parm("list")
list_hda = listparm_hda.multiParmInstances()
children = kwargs["node"].children()

for child in children:
  if "wrangle" in children:
    wrangle = children
  else:
    continue

listparm_wrangle = wrangle.parm("list")
list_wrangle = listparm_hda.multiParmInstances()
i = 0

for parm in list_hda:
  p1 = parm
  p2 = list_wrangle[i]
  
  p2.set(p1)
  p2.expression()
  
  i += 1
