1) Geometry with none constant toplogy - no motion blur.
varying topology mesh have motion blur if carying velocity data, but the Motion Blur is wrong: hundred times too low, so may not be noticed.
You can try to increase the value of the velocity data using a
polycolorMod
node, but vectors are incorrect anyway.

Motion Blur for varying number of particles have been improved but is still unusable because of a nasty bug : when a particle die this triggers artifact and wrong MB at this frame...
Also for efficient rendering of lot of particles with Octane, one have to use direct rendering of particles (so not using instancer) with the "sphere primitive" feature,
This feature is in Octane Core since more than one year but sadly this is still not supported in the Maya plugin.
So I confirm, the Maya plugin is useless for rendering varying toplogy mesh MB, varying particle MB or large number of particles.You need to use Octane Standalone for this.
