System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3090/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 472.12

Blender Version
Broken: version: 2.93 shipped version of BAT

Short description of error
BAT does not seem to correctly pack VDB simulations that aren't made inside of blender using the Fluid Modifier.

The included testing files in Blender Asset Tracers source code use an example where the VDBs are cached from inside Blender and use a Fluid Modifier.

In my use case I import a volume object into the scene, and then feed it a filepath to the VDB cache. On packing it will just outright skip the imported VDBs.

Exact steps for others to reproduce the error
Below is an example folder setup with a blend file and a 10-frame simulation.test_project.zip

The simulation has already been set up inside the blend file.

Using BAT to pack this test blend file will yield in the simulation not being packed.

As a note for this, I would think any solution to have some sort of gate the user has to accept/agree to, since caches can be quite large and potentially exponentially increase pack times. Often times we will have VDBs pre-packed if they don't change to decrease upload times.

Can confirm, sounds like a TODO to me.

This has been merged in #92884 (only in main, not released yet).

With a caveat regarding VDB marked as packed inside blender: #92884 (comment)
