I'm having a weird "lightning" / "color" problem. It's hard to explain but when roaming around (outdoors) sometimes the colors seem to get more saturated (darker). The weird thing is that this happens in certain areas. There's always a definite "border" beyond wich it suddenly happens (and it changes bach when I backtrack). It happens during daytime as well as during nights. It doesn't cause real problems but breaks immersion of course. I would guess it has something to do with the weather mod I'm using (All Natural).

Here's my load order from Wrye Bash:

I would guess it has something to do with Ambient Dungeons, which specifically includes such functionality. You can turn it off in the ini though.

Do you have transitions turned on in all natural? I had sudden changes of color(along with weather) until I turned that on .

I'm not sure I'll have time to test it out this evening but as soon as I hit another of those weird transitions I'll test both those ini tweaks out. I''l keep you posted.

You need to disable the forests/outdoors option in the Ambient Dungeons ini. I can't remember the exact name, but it's fairly obvious in the file which one it is.

Indeed, I changed ADQuest.ForestEnabled to 0 and the problem seems solved. Thanks!

I never would have looked at that mod as the "guilty" one. I thought it only affected indoor areas (hence the name Ambient Dungeons ).
