Trying to set up some license limits on farm resources.
When using Husk to submit arnold renders via the HdArnoldRenderer, I'm guessing it needs an arnold license, but does it need any of the licenses from the houdini side? like engine or karma?

I have a top HDA-level multiparm setup, where a user can click on the plus sign to add additional fields. And lets say it adds an empty string field (name#), and a float value slider (value#).
Inside the HDA, I have a simple attribute wrangle, and I have setup a similar thing with the multiparm, and also the same string field and float value param.
It's easy enough to link up the multiparm itself via 'paste relative references' since it's a single field that's always present. However, I'm wondering how to have the # fields dynamically link up. I've linked this up before via python when dealing with python interactive viewer states, where a mouse event will run code to 'link' up the values. But is there a non-python way to do this?
Or do I need to setup a python callback script in the parameter definition?... I've personally not used callback scripts much in the parameter description field. How would I set this up?
thanks!

ah perfect, exactly what I needed. Thanks!!
