If when you say "doesn't seem worth the space it takes up" you mean a hit to FPS, then don't worry about that, the smoke doesn't affect FPS. If you meant hard drive space after installation, it's no different to installing without smoke, as the smoke effect NIF is already installed as part of the original game files.
EDIT
And with regards the video, the non-AWLS part shows rain, while the AWLS part is clear night, how about forcing rain for the AWLS segment too, to get a more accurate comparison (darkness levels will match).
You could use the console command "fw 38EF2" to force rain.
I have yet to attempt commenting on anyone's blog, so I'm not sure how that procedure works. Sorry if it's irritating, though. Wish I could make it allow anybody to do it.
I actually meant worth the physical space in the world. I've installed mods after AWLS in the past and the smoke would be displaced due to building movement. That would be the only time I would ever notice the smoke; otherwise I tended to completely ignore it. Since it obviously was just making my experience in the game more confusing, I decided this time I would just leave it off. The windows are the more impressive part, anyway (in my opinion).
I'm actually not entirely sure whether adding rain via the console would work the same way, since I have All Natural. I might have to remake the video completely and just make sure the weather remains consistent before I start recording for each part. Thanks for all the help; I greatly appreciate your interest.
