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:
Fancy Bullets
type
circle
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
