Sorry for the delay. I had some IRL problems. Anyway, In order to set as children, I just drag the actor beneath the other in the world settings. But when I play the game, almost all children lost its parents. Probably something in the code?
I am having a different problem that I cant seem to know how to fix it…After I attach a component in a parent, the sweep from move actor location stop working for the parent. Everything overlaps it and only block when something hit the child (the attached component). I want the opposite to occur, the sweep/block occurs when something hit the parents and not the child. Look how I am attaching the components in the screenshot.
I just realized that all my objects are using static mesh as root component. That could be the issue of the attaching? Should I remake the BP in order to use a scene component as root?
