How to export a volume from Houdini

Firstly, you have to install Unity_VFX_Tools.hda to your project. Download and import it from the VFXToolbox repository.

You can export a .vf file using Volume Exporter SOP. There are a few things to take care of:

• It only supports the standard volume. If you're using a VDB volume, you have to convert it to a standard one.
• It only supports uniformly sized volume (x size == y size == z size). You may have to resize it before exporting.
• The default wrap mode of .vf file is "repeat." It should be changed to "clamp" when using a distance field volume.

For details, please see the example Houdini project contained in the Houdini directory.
