This is the result so far after I exported all the elements in blender:

Question1: how do I export whitewater separating spray from the foam and the bubbles? I am exporting whitewater using alembic to blender and it works great... However at the moment it's all in the same file, foam, bubbles and spray. While the former two I think can be rendered together, I would like to have the spray on a separate alembic or even better VDB so I can render it as a volume.
How can I do so? Here you can see my current setup... I see that in the whitewater_IMPORT node group houdini extract some volume info from the whitewater particles so I tried to export those as a VDB but once I imported in blender I think that ALL the whitewater has been exported in the VDB not only the spray. I guess I would have to isolate some part of the whitewater based on some attribute, but I am a bit lost here... Can anyone give me a hand please?
Question2: Is there a way to automate all the steps of the simulation caching process? So far I've been doing R&D but when the time for the final simulation come I would like to automate a bit the baking process. At the moment I cache in sequence: flip sim, whitewater sim, mesh and then I export the mesh and the white water to VDB. I would like to know if I can create some kind of BATCH of those actions so that I can leave the computer to crunch overnight and it will automatically start the next step after finishing baking the previous one.
Thanks everyone for any help in advance!
