You can just use a ROP Output Driver or File SOP set to export files as my_file.$F3.vdb

Because H14 uses OpenVDB 3.0, and afaik nothing else supports it yet, you'll have to set HOUDINI13_VOLUME_COMPATIBILITY to 1.
I'm o.d.d.

3Delight now supports v3:

Edit: more testing require as the test I had made used a normal pyro volume, which is non-vdb.

Edit2: Works fine with the ConvertToVdb node.

thanks - where do I set the env var? Is it a terminal thing or do I set it in a Houdini text file, like Maya's Maya.env?

anyone know what version V-Ray for Maya uses? I can't get it to work.
