==== fog ====
Not to be confused with atmosphere's height fog. This one works when atmosphere is disabled and appears only in Shadow Generations. Similar to light scattering, does not affect the skybox.

* '''color (vector3d) :''' The colour of fog in RGB. If negative, will look near pitch black.
* '''intensity (Float) :''' Fog brightness. If negative, will cause the '''color''' parameters to work inversely. Another way to put it: if the colours are negative with a positive intensity, the fog will look the same as if the colours were positive, but the intensity was negative.
* '''skyBlend (Float) :''' Works between 0 and 1. Determines the influence of the lighting in the fog colour. If 0, only the colour set in the '''color''' parameters will show up; if 1, only the lighting will affect the fog colour and intensity. (Probably a combination of the sun instance and IBL?)
* '''skyMips (Float) :''' ''"Celestial blur coefficient"''. Only works when '''skyBlend''' is above 0. Only works between 0 and 1. Blends the fog colouring from the lighting of the sun instance with the colouring from IBL.
* '''distanceFog :''' A struct containing one of the two layers available for fog. Both can be used at the same time.
** '''nearDist (Float) :''' The distance from the camera at which distanceFog starts being rendered.
** '''farDist (Float) :''' The distance from the camera at which distanceFog gets to the maximum strength or thickness.
** '''influence (Float) :''' Works between 0 to 1. distanceFog transparency.
* '''heightFog :''' A struct containing the other layer available for fog. Both can be used at the same time. Not to be confused with atmosphere's height fog.
** '''minHeight (Float) :''' The Y coordinate (height) at which heightFog starts fading out.
** '''maxHeight (Float) :''' The Y coordinate at which heightFog has completely faded out. If '''minHeight''' is greater than '''maxHeight''', fog will look like it comes from above. If lower, it will look like it comes from below.
** '''nearDist (Float) :''' The distance from the camera at which heightFog starts being rendered.
** '''farDist (Float) :''' The distance from the camera at which heightFog gets to the maximum strength or thickness.
** '''influence (Float) :''' Works between 0 to 1. heightFog transparency
