The Atmospheric class lets you set up volumetric rendering effects with MAXScript. You can create atmospherics like fire and fog, access various properties on them and maintain their list of gizmo nodes such as lights and atmospheric helpers.
The classes derived directly from the Atmospheric class are described in Atmospheric Effect Types.
The properties, operators, and methods that are common to all classes derived directly from the Atmospheric class are described in Atmospheric Effects Common Properties, Operators, and Methods.
The Atmospheric class is derived from the MAXWrapper class, and inherits the properties and methods defined for that class. These properties and methods are described in MAXWrapper Common Properties, Operators, and Methods.
