Unreal Engine 4 for ArchViz

I'm stunned looking at this demo. This could serve as a great presentation to potential house/apartment buyers where you let them walk freely inside. I think I'm going to develop further in this direction now that a game engine can give such a real feel, almost like renders. Real time presentation and video recording possibilities justify the time needed to setup everything in an engine, opposed to having to wait for a XY time needed for rendering an animation to finish. Nice, really nice...
