Hi cahitburak,
thank you for the prompt answer. It works!
I did try various combinations of this, while experimenting, but it never worked. The reason is I used to put the path like this: /Game/TopDownCPP/Blueprints/doorBP**.doorBP**
Because this is what I get when I click on ‘Copy Reference’. So the culprit was the extra .doorBP…
Thank you very much.
Bonus question: I frequently read that hardcoding the paths is a wrong practice, because when you package (cook?) your build, the BPs are left behind. Do you know if this applies to this case, and if so, how can it be solved?
