[Request] Add ability to combine physically simulated objects


What I mean by the title is it would be nice to be able to take several physically simulated objects, and be able to attached them together so they behave as one single rigid body object. Solidly constraining multiple bodies together just doesn’t work nicely, as that results in lots of movement and jiggling.

And before people suggest I use AttachRootComponentToActor or similar functions, using those takes away the physics of the child actors, the parent actor would be the only physically simulated object. Thanks!

We are actually investigating this at the moment! It does add quite a lot of complexity (PhysX doesn’t have support for this, so under the covers it would be one physx rigid body representing multiple unreal components) so we want to make sure it won’t be a performance problem or introduce bugs.
