The Export VDB operator can be used to export VDB data to disk.
Enabling this setting will cause any existing .vdb files in the output path to be overwritten, any time the simulation progresses.
Because VDB data is not cached on a per-frame basis, a previously-cached sim must be recomputed during manual export.
The Export VDB operator will attempt to notify scene VDB loaders that their data needs to be updated, but only some loaders are officially supported for this task. The officially supported loaders are: PhoenixFDFire containers and RedshiftVolumeGrid containers.
