Overview 


The Atmospheric Effects Render Element stores only atmospheric or volumetric participating media such as Environment Fog or Aerial Perspective. This render element can then be used to enhance or color-correct just the atmospheric component of the image during the compositing process.

When atmospheric effects or fog is included in a scene, they will render into the Beauty|RGB channel, and should also be output as the Atmospheric Effects Render Element channel for compositing use.
