Nox-like line of sight ?

Nox-like line of sight ?

Hey.

One thing I [b]really[/b] like about Nox is the line of sight feature. You can't see things behind walls. Even things behind doors if doors are closed. Actually not just thing - you can see nothing around the corner, black area.

I think it makes the game look much more interesting (and atmospheric). I would link two youtube videos, but I don't know an obvious way to do that without my post being marked as spam. How do I do that ?

Does it sound doable to implement a similar feature in FLARE ?
