I was hoping that Octane could natively render Phoenix FD, but it looks like it cannot.

Looking online I found that you need to export the simulation in VDB format, and then import the VDB in Octane to be able to render it.
So I exported my sequence in VDB from the Phoenix FD exporter.
Then in the Octane menu I selected Octane VDB, and I have loaded the first .vdb frame of my simulation. I assigned an Octane material and hit render. Nothing is showing up.
the Octane VDB window has a ton of parameters, but I have no idea how to use it.
I looked on YouTube for tutorials, but I couldn't find any.
Can anyone point me in the right direction please?
