VRayVolumeGrid

This page introduces the Volume Grid geometry object.

Overview

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.
