BWoods 1 Posted May 2 (edited) I have an HDA with a parameter that allows users to return a selection from the viewport (same type of parameter used on blast nodes etc.). I have a callback script that I want to run whenever the artist makes a selection, however, the script only seems to execute when the string portion of the parameter is edited. For example if I manually type the name of an object into the parameter the callback script executes as expected, but if I use the arrow button to select the objects in the viewport and hit enter to confirm my selection the callback script is not executed. This obviously isn't very useful or intuitive for artists. Does anyone have any workarounds or suggestions on how to get this functioning the way one would expect it to?
