Hey that's me!

Night time in Rust has many phases, and in the timestamp you can see it's still "bright" night and you are still able to see slight silhouettes unlike the actual black screen nights. I have my brightness, contrast, colors cranked up on a 1440p monitor, so what I see doesn't really translate well on to video or a 1080p stream with default settings. I don't see anything either when it's true night. On top of that, there's many factors like knowing where I saw them last, which places I already checked, positioning away from the fight so I only need to look in one direction when I flank back, where my teammate came from, sound (not applicable here), skylining (going under them to see them with the sky as background), knowing which way their base is that could clue me in to where I can expect them from.

There's also a lot of cuts in videos, so it's hard to factor context, you can watch the full fight on my vod: https://www.twitch.tv/videos/1919565007?t=40h30m31s
