Splendid, thanks!
I tend to agree with you,
tonschk, it has to be the DynEnv mod doing it because I pulled
sober's fog mod just to see what happened and that made no difference whatsoever.
Now, if only I could find out what it is about DynEnv that creates those permanent dreary skies so I could get rid of that, because the rest of the mod is fantastic.
(Addendum: and, as I mentioned, what is completely baffling is that as soon as the sun starts setting, the skies DO come out in all of their blue, purple, indigo and red glory. It's just during the daytime that there's nothing but grey.)
