VolumeGrid

This page provides general information and links about the V-Ray Volumetric Grid.

Overview

The V-Ray Volumetric Grid allows you to load, shade, and render grid-based simulation cache files, unlike the Environment Fog, which is a general-purpose volumetric shader and requires no files on disk.

In addition to volumetric rendering, the V-Ray Volume Grid supports Isosurface rendering and meshing.

Currently, the following file formats are supported:

• OpenVDB (.vdb) - Supported by Houdini® and RealFlow®
• Field3D (.f3d) - Supported by FumeFX® and Maya® (using 3rd party plugins)
• PhoenixFD (.aur) - Phoenix FD® native volume format
