Rendering CGTrader scene in Unreal?

Got a scene from CG Trader and want to render it in Unreal. When I imported the FBX/OBJ, left the default import options which said auto collision generation, no skeletal meshes etc. All the files got dumped into an unreal folder in content browser. But these are all individual untextured parts. I was expecting an entire scene like I saw in CGTrader.

  1. Do I have to reassemble these individual parts? its tedious because the reference is not helpful. (and what did I pay for?)
  2. How do I texture these individual parts?
  3. how do i light up the scene? Didn’t I get a well lit scene from CG Trader?
    Please help
