Ho to get motion blur rendered from particles?

[Alexx31]

Thanks, but I tried it now again, and with "as instances" it doesn't render at all, then it becomes invisible.

I have also set it on a short time, to make sure, that is hasn't to do with time.
It's only rendering as a triangle mesh
(I'm watching it in Vray IPR in the VFB)

The same is happening with a tyCache Object (with Edit Poly Modifier on it).
