fluid operators don't work with vdb ?

[oumoumad]

I wonder if this is an issue or if it's just a feature that hasn't been added yet? Basically when I switch my output format in pheonix FD to .vdb the particles in both birth fluid and fluid force do nothing until I switch back to the .aur format. We prefer using vdb that way our simulations can be re-used in other applications and other renderers such as Arnold.
