A new demo just dropped, based on the Team Fortress 2 map.
Looks impressive, especially around the middle of the video, where they move the light source around the building. Definitely much better than what GamesFromScratch presented…
There’s a little more information and discussion with OP on Reddit, if anyone’s interested.
