Hi,
Throughout many of my installs I've found that blue fog randomlly appears every 10 mineuts or so- and rediculously close to me, so I can't see more than a few feet infront. I use streamsight along with enchanced weather- is this the cause?
It's VERRRRY bothering, considering I use so many graphical enchacement mods and can't see any of them!!!

Make sure you're using Streamline 3.1 plus the patch. I get weird fog settings using Streamsight extremely seldom so it seems quite stable to me. Not using EW, though, but rather All Natural.

will try updating to the patch, thanks If it persists I may as well use all natural- so long as it has a darker nights setting...

Yes it has.. and fully customizable in the INI

And if you use AN, I would recommend turning off streamlines streamsight and have a look at the settings I had a play with here http://www.gamesas.com/index.php?/topic/1140299-relz-weather-all-natural-thread-30/page__view__findpost__p__16678883 in the spoiler... it works really well if you want a similar setup to redbags fog

Though one change to that post linked above - I would now use ....

In My Documents\My Games\Oblivion - Oblivion.ini - UgridDistantTreeRange and UGridDistantCount both set to 14 or even 16 (depends upon your preference and machine capabilities with distant trees/objects of course but for the AN fog ranges I used there I think 14 or 16 is a good match for those)

I am not currently using AN because for our setup had to go back to obse 0018 (please dont take this as a recommend not to use AN, a lot of people are using AN without the array errors I experienced - it only happens in rare cases at the moment as far as I have seen, and by all accounts it should not be happening at all - under investigation), really missing it personaly though, gone back to redbags fog for now (and also not using streamsight with that, UGrids with redbags is a good range match at about 12 for redbags clear day fog (which is the max ranged fog)) but when the array error problem has been resolved I will be re-installing AN.
