Datasmith brings entire pre-constructed scenes and complex assemblies into Unreal, regardless of how large, dense or heavy those scenes may be. Rather than forcing you to deconstruct your scenes and assemblies into individual chunks, then pass each chunk to the game engine separately through an FBX import pipeline, then re-assemble the scene in the Unreal Editor, Datasmith re-uses the assets and layouts that you've already built for other purposes in other design tools.
