[Feature Request] Exponential fog should have vieiwing angle limitation

I’m using the exponential fog to restrict distance view. It would be nice if there was a variable “maximum viewing angle” beyond which the fog would completely disappear so that looking up into the sky will not leave the sky untouched by the fog. I know there is the “Fog Height falloff” field but it is not quite the same since you can not really get the zenith clear of fog unless you move the fog way below the character position and then you don’t really get a good fog in the horizontal.
