Volumetric velocity?

[dan_plattner]

Hi everyone,
I'm not sure this is the right place but maybe you can help me?
I'm using FumeFX to create helicopter dust simulation and because I can't render it directly with V-Ray because then I can't achieve the velocity pass.

So I tried to render the simulation with V-Ray volume Grid and it looks fine,
but the problem is that there is still no data in the velocity pass.

I'm not sure it's possible to get the velocity pass like this but if it's possible please let me know what I'm doing wrong...
And if it's not possible please let me know also.

Thanks,
Dan

Try using Volumetric Geometry mode on your Volume grid and give us a feedback. For more information you could refer to our online documentation:
