need help with creating smoke

[FlyingFish]

I am trying to create a smoke effect for a simulation and I am not sure how to make it work in Vizard...

I made a smoke object in 3D Max with particle spray and exported it as .osg to Vizard. I added motion blur to the particle so that it would resemble trails of the smoke. The problem is that when I export it, the motion blur effect does not show up when run in Vizard. I opened up the osg file and tried altering a few parameters but couldn't find a way to make it look more like smoke. Is there any ways to enable motion blur or is there a better way to create a smoke effect in Vizard? thanks in advance.
