This is one of the few benefits of UE4. Real-time Lumion 7 is bad. The end render output however takes about the same time as UE4 when exporting from sequencer.
And the thing is, rendering is all you need. Interactivity in architectural presentations are still very gimmicky. During client, board, city, or community meetings, it’s awkward trying to teach old rich hags how to use a controller (majority of people keep getting stuck walking into walls). Walking through a space or changing the color of a wall is neat; but in the end it’s just a gimmick. What needs to be conveyed is the concept of the architecture, and the most efficient is a simple fly-through animation.
