How to export vehicle?

As guys you see, i seperated all parts of my vehicle. The main ask is how should i export and import in ue4? In ue4 there is an option merge actors, while importing it takes as one object. If i check it, how would my vehicle be ? Can ue4 read all seperated parts so i can set them for glass breaking and damages for per part of vehicle ? /

separate parts are required in order to perform separate actions.

You can set all with skeletal mesh, and in rutime can break joints.

‘‘Seperated parts are required’’ In one object ? Or all that parts are like diffirent objects ?

Hmm. Let me check this. Thanks
