Hello, is this Clockwork node broken in 1.2 ?
Can you open the Custom node and copy the contents to the master graph, plug it in and see what warnings you are getting? The warnings are hidden while wrapped in the custom node and it’s impossible to see what’s wrong with your current image.
I found got a simalr result in one of my scripts. The reason for the null is in my case that the model include filters with name including special signes like æøå (Danish letters) After a bit of renaming to the filters the node “SelectionSet.BeElements” works well.
