Ok, thank you so much.
Sounds complicated for a beginner, however I can create a widget, run that, execute the blueprint, ok. But it is so hard for me to find out what exactly to search for setting it up. Take my example to show/hide the foliage. I draw a button in the widget, then switch to OnClicked-Event in the graph. But what next?
Is there a way to see what the editor does unter the hood when switching on/off via the menu? In a log file or so? Output log does not spit out anything.
Thanks!
