### Example: Fade Out Radius

 

In the example below, a cube is used as a volume for the [VRayEnvironmentFog](https://docs-chaos.atlassian.net/wiki/spaces/VMAYA/pages/111739136).

To set this up, follow these steps:

1. Specify a VRayEnvironmentFog as the **Environment volume** in the [Volumetrics Overrides](https://docs-chaos.atlassian.net/wiki/spaces/VMAYA/pages/111739143).
2. Next, assign a VRayMtl to the cube with its **Opacity Map** set to *black*.
3. Add the cube as a member of the Environment Fog set as shown below.
4. Finally, add the **Fog fade out radius** attribute to the cube and enable **Per Object Fade Out Radius** in the VRayEnvironmentFog attributes.

> Versions of V-Ray prior to 3.6 supported disabling the Primary Visibility of the container object. However, this method is deprecated, and setting the Opacity to Black is now recommended.
