This setting overhauls the behavior of fog calculations.
|
|
|
|
Normally the fog start and end distance are proportional to the viewing distance
|
|
and use the fog depth set in the fallback settings.
|
|
|
|
Enabling this setting separates the fog distance from the viewing distance and fallback settings and makes fog distance
|
|
and apparent density dependent on the weather and the current location according to the settings below.
|
|
|
|
Unfortunately specific weather-dependent fog factor and offset parameters are currently hard-coded.
|
|
They are based off the default settings of MGE XE.

Non-underwater fog start and end distance are calculated like this according to these parameters::
|
|
|
|
fog start distance = fog factor * (base fog start distance - fog offset * base fog end distance)
|
|
fog end distance = fog factor * (1.0 - fog offset) * base fog end distance
|
|
|
|
Underwater fog distance is used as-is.
|
|
|
|
A negative fog start distance means that the fog starts behind the camera
|
|
so the entirety of the scene will be at least partially fogged.
|
|
|
|
A negative fog end distance means that the fog ends behind the camera
|
|
so the entirety of the scene will be completely submerged in the fog.
|
|
|
|
Fog end distance should be larger than the fog start distance.
|
|
|
|
This setting and all further settings can only be configured by editing the settings configuration file.
