This page introduces the volumetric and environment effects for V-Ray for Maya.
The Volumetric effects in V-Ray simulate fog, atmospheric haze and participating media for a number of image effects. Volumetrics also include Volumetric Grid rendering that works with grid based cache formats to create effects such as dynamic plumes of smoke.

True Atmospheric Effects
True atmospheric effects are applied throughout the entire scene as viewed from the viewport. While parameters give limited control over the appearance of the effect, atmospheric effects render faster than volumetric effects.
- Aerial Perspective - Adds a depth effect by causing distant objects to be less distinct, as they are in real life when viewed through the Earth's atmosphere.
- Environment Fog - A fog effect throughout the scene, with control through maps and distance settings.
- Simple Fog - Very simple fog with no maps.
Volumetric effects use a volume to contain the atmospheric effect. While volumetric effects offer a great deal of control over the placement of the effect, they take longer to render.
- Scatter Fog - Scatters fog within a volume.
- Sphere Fade Volume - Places the fog effect within a spherical gizmo, with a fade-out at the edges of the gizmo.
- Volumetric Grid - Imports grid-based volumetric simulation data from external programs to create fire, smoke, and fluid simulations within V-Ray for Maya.
