Hello,
Completely new to Houdini. I'm trying to create a vector file to use in Unity.

I found VFXToolbox:
https://github.com/Unity-Technologies/VFXToolbox [github.com]

This has DCC Tools which enable the export of .pcache and .vf files. I would like to use the Houdini Volume Exporter to create a .vf file.

When I import the tools into Houdini Apprentice it looks like this:
https://drive.google.com/file/d/1r-Hy1-V4HlUXq-_T3TDbprAUCDXNedfM/view?usp=sharing [drive.google.com]

The text flashes red and then the window closes. Not sure if this is expected or not.

From what I have been reading the export tool should be a SOP node. But looking at the available export nodes after importing the tools, all I see is in the below image.


Am I doing something completely wrong or are these tools only allowed to be imported in paid versions of Houdini?

Any help is appreciated.

Cheers,
Shane

What tool are you using to export .vf files from Houdini? I'm not aware of any built-in export support.

Hey,

The tool/plugin is available in this .hda file: https://github.com/Unity-Technologies/VFXToolbox/tree/master/DCC-Tools~/Houdini [github.com]

I just made some progress on this. I have created the .vf file, now trying to use it in Unity.

hey Shane!
i am in the same spot, when i import the vfxtool DCC, the red flash appears, and closes.
Not seen the SOP volume exporter, like in your second post. some clue?

Hey Shane
I have already imported VFXToolBox，but i dont know how to use Vloume_Exporter node,How can I save a VF file on my disk?

Hi,

To save VF file you must use

1. isooffset node
- set OutputType to : SDFVolume
- set Name : vel
- set Uniform Sampling Divs to : 64

2. connect your geometry node to isooffset node
3. connect isooffset node to volumeexporter node (from Unity plugin imported to Houdini)
4. in volumeexporter set
- OutputFileTyle : VF
- VolumeType : Scalar
- Volume name : ver
- check box Export

this save SDF to VF file …

Has anyone tried to export a vector instead of a scalar? I want to generate a distance gradient with the toolbox but only get strange results.
