Its very amazing honestly. The only thing i must say is i wish it was bigger i.e. a whole house instead of just a room, but i understand that they want to showcase specific features of the engine so thats why the scene is more compact :-).
One thing of note. there is a fly through of the day and night scenes but they forgot to make the mantinee play at the level start…
wanting to play around with camera movement more i created my own camera paths here!
