Fog in my house?

[MuyTom]

Is my game glitching, or should I expect heavy fog to be inside my house also? The whole house is either a verified room or cellar. Heavy fog outside. I would have expected the house to be clear though. I can barely see inside...maybe only 3 blocks Infront of me and rooms are up for 14 blocks long/wide.

I've had this happen too. I find it annoying. I don't know if it's intended or not. Certainly fog has caused big problems with lighting in deep caves. My current theory is that fog just needs a lot more adjusting.

Fog is one of those "Whack-a-mole" issues in Vintage Story. Every time you think it's beaten, back it comes.

The simplest, shortest solution is "Move your house." Some areas are simply more fog prone than others.

Now, for the long answer.

Fog has a number of factors that makes it more likely, or heavier. If you are in a particular area, or elevation, and the weather is just right, then you get fog (or cloud or haze). See:
https://wiki.vintagestory.at/Weather#Clouds_&_Fog

Fog is also influenced by some mods. If you have mods which impact light levels or weather, try disabling those.
(It is assumed that you are on the latest stable version.)
In particular any mod that has BOTH "Ambient Particles" and "Override default values" checked in the World Edit.
To see these values, you would need to switch the game mode to Creative (/gamemode creative), enter "~" (tilda) to bring up World Edit and then look at the values on the right.

CAUTION: I'd recommend that you take a world backup before you consider touching those values.
(I got more Creative World into a bit of a weather tangle while testing fog.)
If you wanted to just kill the fog, then switching the fog levels left should do that.

I've been adding to a post at the Issue Tracker which you may wish to check out here:
https://github.com/anegostudios/VintageStory-Issues/issues/6228#issuecomment-3396800796

This is on-going. 

My understanding is that fog is an "area" affect which does not take account of whether something is a "room." 
I could be wrong on this, but that is my guess as to how it is working.
Would I like it to take account if you are in a room? Yes, yes I would. Does it currently? There are issues.

Long story short, if you haven't shot yourself in the foot by doing something with a mod or a command or World Edit, then I would recommend moving to a better climate/position. The world is large. There are plenty of nice places without fog.

NOTE: Fog is usually a TEMPORARY event.
So maybe just wait a few days.
Maybe the rest of the year is just fine?

That is a hefty and much appreciated reply. That took some thought and time so very much appreciated! All that to say that that is kind of a shame, because when outside, I feel the fog adds a vibe and effect that just bring some added nature, variety, realism to the aesthetics of the world we live in. It's pretty amazing and oddly "pretty" if you can all it that when it's outside...much like the rain. I want it to remain in the game it's just a shame that you, as yet, aren't shielded from it by being in a "room."

You really should be. I put up with it because, as you say, I like the fog outside.
