VRayVolumeGrid is a special kind of volumetric effect that works with grid-based cache formats, compared to Environment Fog which is a general purpose volumetric effect. The Volumetric Grid reads its data from an input file which supports grid-based representation of the volume. Currently, VRayVolumeGrid supports three volume formats: - OpenVDB (.vdb) – Supported by Houdini ®, FumeFX ® , and RealFlow ®
- Field3D (.f3d) – Supported by FumeFX ® and Maya ® (using 3rd party plugins)
- PhoenixFD (.aur) – Phoenix FD ® native volume format

Immediately after the VRayVolumeGrid is created, a dialog appears for selecting the input file. After selection of the input file, a number of options are available to fine-tune and customize the volume.
||V-Ray Toolbar|| > V-Ray VolumeGrid

The VRayVolumeGrid can also be created by dragging a relevant input file inside the active viewport. |
