FumeFX VDB motion vector to maya

Recommended Posts

Hi guys, 

I simulated fumefx vdb with velocity channel in 3DSmax fumefx and i used maya arnold volume to import VDB.

How do i render the the motion vector for the VDB ?

i tried motion vector VDB and it doesn't work. 

any help would be great. thanks

I'm not familiar with importing FumeFX into Houdini, but internally for Houdini, it's expecting to have velocity as a vector parameter named "vel" for it to pickup and use motion vectors during rendering.  Check which parameters are coming in from the FumeFX VDBs, you may need to just rename the velocity attribute.

Here's a link from SideFX's site with some more info:
