Hi all, I am having some trouble with the "on name change" event handler on an HDA. I want to be able to name nodes inside of my hda based off of a new name that I give the HDA after I have dropped it in my scene. The code works as a button but not when triggered on the change name event. I even tried hou.Parm.pressButton() in the on name changed even script but no dice... here is a sample : attached a example otl as well... Is there any other way that I can do this.. Many Thanks change_my_name.hda
