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`](Houdini) directory.
