It looks like I had to change all the stuff highlighted in red. I used to check vertex mb and done. Now it is over-complicated.
Plus why do I need to set generic vel scale to 1 if phoenix fd has general particle velocity option.

Hi coilbook,
I just found out that the real velocity channel is 2, but it appears only if you have "Export as" set to "Mesh"
So you'll need to keep it like that while rendering with Octane, to have a good motion blur.
Channel 1 was the UV channel, there are some values, that's why there is some blur effect, but it's not the velocity..
With channel 2, you'll need to go back to a small Generic Velocity scale..
Here is a small tutorial with samples:
