X-Particles with motion blur only showing up in live viewer Tweet

[DannoKaBlammo]

I'm only able to see motion blur in the live viewer, but not in the picture viewer upon final render.

I'm using an xpGenerator with a polygonal sphere underneath to generate the particles. I've also applied an Octane object tag to the xpGenerator. Caching doesn't seem to make any difference either.

I'm using C4D R20, X-Particles build 895, and Octane 2020.2.3-R3. I've experimented using older versions of each of these but I still can't get motion blur to show up in the final render.

Sample C4D project file to see how things are set up:
