"Merge" Collision-Volumes / Handle multiple Actors as one

Hello everyone,

Quick example: I have multiple Actors attached to another Actor, named Actor X. Now I want to rotate Actor X with bSweep = true. This does work, but only for Actor X, not the actors attached to X.
So my question is: Is there a way to “merge” the collision-boxes of each of this actors to create one volume that includes all the attached actors? If this would be possible I would not only solve this question but also It would save some collision-checks, since those actors can be placed dynamically but once they got placed they can’t change their relativ location to each other, what means they basically could be thought of as one actor. Currently, when Actor N notices a blocking hit, it would need to inform the parent about this hit. For 30 actors connected to one Root-Component this would make 30 Actors to perform collision checks VS just one, without even the need to call any additional function.

So, again, I’m looking for a way to handle the collision-“boxes”/“volumes” of multiple Actors as one object, eg merge them together and set this new object as root.

Thanks everybody :slight_smile:
