Ho to get motion blur rendered from particles?

[rod_sott]

Hi guys! I'm with the same problem.. .can't make the motion blur work with VRay GPU / Vantage... I've tried all possible combinations on enabling/disabling mesh render, instances, particle interface, tyCache, tyFlow itself, enabling motion blur property on object, on camera, Max and VRay physical cameras, adding Edit poly on top... NOTHING makes the tyFlow particles to create motion blur in the render. I animated an object, to be sure that the motion blur is working, and just with tyFlow that its not working. Tyson, @tyFlow , please give us some light on this subject.. I really need to render in Vantage due the render time, and I really want the native motion blur, other than using some in post.. Thank in advance!!
