Elevator BP with switch BP


I have an elevator which is a blueprint extends from Actor class, and a button that can control it which is also a blueprint, and extends from Static Mesh Actor .

I want to add buttons to the elevator’s cabin as subobjects to create a control panel.

If I attach the buttons as a childactor to the elevator cabin, it doesn’t move with the elevator.

How should I add a blueprint as a subcomponent to an other blueprint?

Here’s a video about it: My Ezvid Video - YouTube
