Fog is#nbsp;generally an#nbsp;excellent atmospheric element that can be#nbsp;used in#nbsp;non-commercial and competition works.
Not only does it#nbsp;look very effective, but it#nbsp;also allows hiding a#nbsp;significant portion of#nbsp;geometry, thereby simplifying the artist’s task in#nbsp;detailing.
The reason why it#nbsp;is#nbsp;less used in#nbsp;commercial projects is#nbsp;that fog is#nbsp;associated with 'dramatic view' renders, and such images are less appealing to#nbsp;developer clients.
