Volumetric Fog is a powerful tool in an environment artist's kit. Volumetric Fog is a wonderful addition to any scene that could use a sense of space, whether it be a dusty town, a gloomy cemetery, or a grand throne room. Most implementations of fog, such as exponential or linear fog, are computed at an object’s surface by the Shader that the surface uses. At most, this is once per pixel. Volumetric fog, on the other hand, is computed at intervals in the empty space in front of the camera, independent of any surface. In this tutorial, you will learn to create and adjust Volumetric Fog.
