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

Page Contents ×

 

Overview


The V-Ray Volumetric Grid allows you to load, shade and render grid-based simulation cache files, as opposed to 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 also 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

 

 

 

UI Paths

The VRayVolumeGrid can also be created by dragging and dropping a relevant input file (.aur, .vdb, .f3d) inside the active viewport. 


Extra Tips


The following page contains extra tips for using the V-Ray Volume Grid:

  • Volumetric Grid Tips is an information page containing distributed rendering and FumeFX render settings tips.

Rendering VolumeGrid with any Render Element via the V-Ray GPU engine is not supported yet.

  • Starting with V-Ray Next, Update 1, you need to re-export Maya fluids to .vrscenes if you want to use vrscene caches.
