Hello devs, any word on this? Cycles can do motion blur with Blender fluids while Octane can't.

Hi J.C,
For now, It is a limitation that Octane only supports resharpable mesh with the same vertex number all the time. But for most fluid, the vertex number is varying from time to time.
I am investigating some workarounds(e.g. by involving the velocity) to see whether it is possible to manage it.
Cheers,
DrawFun

FLIPFluids team solved this issue using morphs to store motion vector data (Octane motion blur works correctly with FLIPFluids).
My suspect is that for standard fluids Blender is storing the motion vector information somehow, which is not accessible to Octane.
Maybe converting that motion vector info to morphs would help.
