I've had the same behaviour as in Sjors_Broomscors video while I've been using the advanced esp. By walking up to a building then a just a bit away, back and forth while looking at it, the windows/chimneys will go on and off. But it does happen when you are just walking by normally - the lit states of windows or whether the chimneys were smoking/what size smoke changes sometimes when I got close to buildings, suddenly flicking on or off when I just walked by. It seems silly that when you walk past a whole row of lit buildings their lights will go on and off each when you get to them.
I think what's happening is that some users(including me) really like the Advanced esp because of how you decided to make the lights to be on at evening and dawn, but off in the middle of the night(except Inns/Taverns and Cathedrals)- as opposed to the Medium esp which has all windows lit all night long. However the random chance for the windows to be lit or unlit(or chimney smoke to be on/off or a different size) is annoying in that in can only be checked for when you get close to each building. Would you be able to make a different version of the AWLS esp that's a like a mix between the Medium and Advanced esp? So it has a similar time schedule but no chance for windows to vary so the script doesn't need to check when you enter a cell - which means you will only see them changing beacuse of the time/if raining. A way to get the best of both esps.

Except I would suggest turning all the lights off(except Inns/Taverns and Cathedrals) at 10 or 11pm instead of 1am since they don't have a chance to go off earlier and the occupants need their sleep if they're to get up at 5am.
i.e.
-Inns/Taverns and Cathedrals lit all night long(1 hour to sunset still sunrise, like the Advanced esp)
-Will light up all other windows from 1 hour to sunset to 10pm, not chance based.
-Will light up all other windows from 5am to Sunrise, not chance based.
-Will light up all other windows when it's raining, not chance based.
Chimney Pack Advanced ESP:
-Chimney smoke are set on large during the 6 cold months of the year during the night. They are set on small during the day.
-Chimney smoke are set on small during the 6 warmer months of the year during the night (except on the norther part of Tamriel and in mountains where the smoke is still large). There are no smoke during the day, except when it's raining.
-No chance for smoke to be a different then set by the schedule.
Anyone else think this is a good idea?
On a separate note, is it possible for me to have a Temple of the One that's not lit at anytime just by removing its window textures?
