Also, if I may shamelessly plug, here's a different, more organic look at what a day night cycle might feel like, though the cycle should be even slower than that. Where Sniper uses 15-24 atmospheres (I don't recall how many exactly), I just use four:
https://www.youtube.com/watch?v=7Eih7CW4ph8If Larian could make the atmosphere triggers a bit more versatile, that's be awesome. I wish I could edit the transition time of an atmosphere with a script for example, so I could make the atmospheres have different lengths, say if I wanted a slightly shorter night than the day atmospheres without screwing up the transition times. And it'd be nice to not have the transition could bypassed when you teleport in or out of the transition trigger. Sniper's many atmospheres makes this less noticeable probably, since if you have a different atmosphere for your upstair rooms, then you can have a teleport trigger send you there, and then come back, and while it'll still skip ahead to finishing the transition time, the timer will soon boot up again to transition the atmosphere again, so it won't be sitting there still for very long. That's compared to four atmospheres, which if you skip ahead of the transition time with 300 second transitions, the atmosphere might be stuck as it is for 250 seconds instead if giving that slow transition.
Another option is to have maybe 8 atmospheres to represent 3-hour cycles, and just make the transitions quick (5-10 seconds) but hold those atmospheres, which would also use a lot less CPU than constantly moving the shadows. But not quite as immersive.
Anyway, hope Larian gives us the capacity to add a day night cycle to the main game if we want.
