An actor to another actor. Yes, they both code based. The main thing that, it works fine after you selected each object in world outliner. It looks like this, “Ancor” actor exist in the scene and rotates, then we create some another actor, lets call it “block”, and attaching it using “AttachRootComponentToActor()” from its class. So in hierarchy it’s attached, but it does not behave like child of Anchor. I mean, it doesn’t rotates with Anchor. And if I select it in world outliner it’s gonna behave the way it should. It’s gonna rotate with parent. So I don’t now whether it’s bug or I’m doing something wrong, because I’m quite new to unreal engine. I tried to enable tick function in Anchor children, but the result is still the same. My guess was that, maybe those children actors don’t update transform every frame.
