…One thing came to mind, for realtime ArchiViz would having people walking around doing stuff (since it is realtime) help visualise how people would actually use the space? In “common” 3D renderings they have the people composited in eg. for shopping malls, city spaces, offices, buildings, homes, apartments, etc. I think right now the UE4 ArchiViz in general is very beautiful but somewhat “lifeless”. Just an idea.
