If I remember correctly SniperHF faked some.
I saw that on youtube I think. Maybe he can talk about what he has made.
Have I been summoned

The real trouble is scheduling.
This is sort of my half ass attempt at getting some basic schedules going. It looks a little better now than it did two weeks ago when I made the video. These things you can sit there and polish each individual NPC animation and movement till you die.

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:
Still haven't come to a conclusion on how long it should be for a 24 hour period, but it's much longer than the YT video from before. That was sped up intentionally.
Sniper's many atmospheres makes this less noticeable probably,
That's exactly why.
Anyway, hope Larian gives us the capacity to add a day night cycle to the main game if we want.
I've never even attempted modding MAIN since even some stuff in standalone mods gets locked off by developer mode requirements. I can't imagine what it would take to add it to D:OS 1
