Looks like this.
No idea what's doing it. :|

I sure would like to fix this.
I have only done the frost cave update since last time I played. I haven't reinstalled or anything. No new hardware or anything (I probably have updated my vid drivers since... that's normal though)

If you're not using any mods, I'd call that a bug and report it. I've been in a bunch of caves, chambers, crypts, etc and never seen anything like that.

Run mods ?

Try a file verify.
Right click game name in Library for Properties
Local Files
Verify

If that won't work check your video drivers... maybe roll back to one?

If you run mods you may want to try a clean install by uninstalling and manually deleting the game folder... corrupted or mod files will not be removed with an uninstall.

Oh no... wait... I have found the culprit. I use devcommands when I play. I like to change evironment settings sometimes (I don't like the flashy thunderstorms)
And sometimes I use TOD (time of day) setting to keep it daytime while I'm building.

So using tod to set it to daytime causes this (It didn't used to).
Letting the time of day cycle normally doesn't appear to. When I reset TOD and go in during actual day time, it looks normal.

HAH!!!!

Get your eyes checked.

My gamma was a bit too dark during the day <real day not in game> so I adjusted it a tiny bit mostly due to anime watching. That has brightened the caves up a little in game but they are still dark and require a torch/light in areas to see clearly.

Maybe you adjusted your gamma outside of the game? I don't think the devs changed anything in that regard.

I've been playing solidly for months - the tombs haven't brightened at all for me. :/ The occasional crack in the ceiling lets light in a little but now to the extent you mention. Screenshot?

I did notice a rare room with a crack in the ceiling that can be bright as day. Otherwise it seems to vary a lot for me. I don't know if its your eyes adapting or if it somehow is reflective of 'how deep' the crypt is buried. I would just suggest to the OP to try a couple more and see if they are all like that.

Just played through one, was dark as ♥♥♥♥ without my torch lit. Now a few rooms did have torches or sconces, the yellow mushrooms glow, and the entry chamber has some light from the entrance. Outside of that - dark.

Could it be updated hardware or drivers that have some sort of auto leveling gamma correction?

If anything I would say they have gotten darker since release.

I have been playing since last July and if they brightened the tombs, I missed it.

They haven't changed at all for me. It sounds like it's some issue with your install.

I can't say I noticed a massive difference if there was a change. It's certainly not light daylight in there, more like dusk. But I don't remember it being insanely dark in the past, could be remembering wrong though.

Maybe it might be worth posting a screenie so we can compare?

Last time I was in them, they were pretty dark. You sure this isn’t a big or something? Maybe a setting gone extreme?
