Hello ClockworkOcean. Thank you for the attention to my problem.
Yeah, I believe I did exactly the same.
But it doesn’t work, probably due to the fact that initially
the Child Actor does it’s Construction Script before changing variables in it by the Parent BP.
Do you think it can work like that?
I mean, I probably just have to move the logic from Construction Script to EventGraph…
But I would prefer something like: ReDo the Construction Script if it was possible.
Edit: Aaaah. Actualy I gotcha what you mean. Transfering the whole construction logic to an event (not only variables change) and call it anytime from any Construction script.
Yeah. That solves it 
Thank you.
