Vray Velocity pass, motion blur? (3dsmax 2014)

[3duser]

Hi,
Could I get the motion vector with Velocity pass in render element when I use multiscatter with vrayproxy?

I have an animated object, I am rendering with Vray while adding a velocity pass, I get vector color information which I can use to make motion blur in after effects.
If I convert the animated object in a vrayproxy, I always get the vector information.
But if I use multiscatter with this vrayproxy, I don't get the vector information, everything is grayed on velocity pass.
I tried to generate objects with multiscatter tool in the utilities tab, it work very well but he doesn't take into account the random start animation ( I used a value in "samples" with black-from, white-to)
What should I do to get the vector information?

Thanks in advance for your answer

PS: I noticed the same problem with Vray motion blur, maybe I'm wrong and it doesn't work with multiscatter.
