Skyrim Fog + Sun

Alright so the main thing that is keeping me from really using ENB in gameplay is the strange fog behaviour.

Image
It is applied extremely close to the camera. Only objects that are very near you are not fogged. No setting can change this, although it's less noticable if the fog is darker. But since the fog is such a big part of the background that looks very bad. During foggy weather effects, the fog becomes extreme to the point of being unplayable.

In vanilla, fog is either very light or not there on close objects. Dragonsreach is only lightly fogged from the marketplace. But with ENB, it is completely covered even at close range.

Image
The fog is applied very inconsistently. Some objects are more fogged than others.

As an aside, the sun is extremely weak unless you boost the sun power to unreasonably ugly levels.

There is also the minor issue of SSAO bleeding through the shield but I gather you are already fixing that?

Re: Skyrim Fog + Sun

Fog is not changed by distance or density, only it's gamma and intensity under [ENVIRONMENT] category of enbseries.ini file, brain and eyes foolish you. Game fog is not similar to distant fog in other games, it's have two colors, one is applied all the time even near distance, another is far distance fading. Decrease fog intensity by FogColorMultiplierDay.

Not the mod issue also (and never saw such behavior at all).

The sun in game do not have hdr intensities, how it could have reasonable low value if sun in real life is extremely bright?

Re: Skyrim Fog + Sun

I messed with the fog settings a lot and it really has to be a bug. There is no way to replicate the correct fog intensity in ENB

Re: Skyrim Fog + Sun

What do you want? To proove that my code have bug or that you don't know how it works?

Vanilla vs ENBSeries:

With UseOriginalPostProcessing=true that I use ENB precisely to escape.

EDIT: Okay, so after a little more experimenting I think I've found the issue. Fog and presumably other things like light colours, are not correctly gamma corrected. You can resolve this with a global gamma correction of 1.8 ( [COLOURCORRECTION]GammaCurve=1.8 ) and adjusting the fog power to 0.5555 to bring the hue back up to where it needs to be. Like so:

Correct Fog

But this causes the textures to be oddly blown out. If you use the colourpow to correct it, the texture hues become too dark because it stacks with the global gamma. If you adjust the global gamma to be 1.0 and the colourpow to be 1.8, then the textures will look correct. But the fog problem is back, although the fog hue is now correct at a power of 1.0:
