VDB EXPORT DOESNT WORKS !

When I Press Export Current Frame as VDB nothing is pupping out to export VDB.
is this some kind of bug or Im doing something wrong?

The GUI for the conversion progress is still incomplete. It will just silently convert the VDB files. You can find them in a sub-folder of the cache folder.
The path of the cache folder is set in the Parameters tab of the create node. That’s usually %HOMEPATH%\ReactionsData\Caches\XYZ.cache
