hi @ramizender
An actor can only have one parent.
If you wish to use an actor as a “link” between two actors, you’ll have to attach it’s root to one actor, and use rotation so that your actor meets the second one. In Any way, you’ll have to use some blueprint.
It depends on what you are trying to achieve. If you want to have a flexible chain-like behavior, you can use a SplineMeshComponent to do so. A rigged chain can also do the trick.
