[fixed?][0.4.*] Fog in caves is bad idea

[Fixerol]

Fog in caves looks bad (it lights ups caves in wrong places and it looks bad), and dirty hack to darken it when looking down is noticeable (and can behave weirdly above ground too iirc), any ways to improve it? Why not just disable fog automatically below -20 (or other typical depth) or darken it depending on light level?

[prof-turbo]

There are 15 different light stages.
Maybe that fog should be adapted to those stages :
15 = 100% of fog light
14 = 94,4% of fog light, etc...

Would it be possible to do ?

Aren't light stages per-node, not per-scene?
Fog can only be changed for the whole scene.

Did you disable noclip and fly when you took the screenshot?

Enabling fly makes the skybox stay light blue.
This isn't really a bug it's just how MT works.
Fog colour/brightness must always blend to skybox colour/brightness, the dirty hack is actually a good attempt at detecting when the skybox should be darkened, it fails often but is a difficult thing to get right.
Luminous fog underground is not realistic but i like it it's atmospheric.

yes

I loose sense of adventure if my "dark" caves are lighted up, it is not only wrong and incorrect, it makes game easier in caves.

I agree with Fixerol. It's not about realism. The fog in caves makes cave exploration too easy since it clearly tells you where to go even in pitch darkness.
You might not even need torches or something.

No matter if this is considered a “bug” or not, it is not really a good idea IMO. But I have no idea how this could be changed.

[Fixerol]

It seems that fog glow in caves was caused by free move turned on.

[Wuzzy]

No, this is a common thing in Minetest and noclip/free_move mode does not matter here.

[Fixerol]

>mode does not matter here

It does matter, amazingly :}

[paramat]

It can happen like this https://github.com/minetest/minetest/issues/3577#issuecomment-223513323

However yes it can sometiimes happen at other times due to the imperfect method that tries to choose whether the sky should be darkened or not.

This problem was mitigated in recent dev. If both noclip and fly are not enabled you should not see this brightened fog in caves anymore.
