Alembic Velocity to Motion Blur

[JonKaiser]

Hi,

I've rendered out a fluid mesh from Houdini as an .abc file with a v-attribute. I can't get either motion blur or the motion vector pass to work.
Obviously some render engines have their issues calculating motionblur from meshes with changing topology, but as I have a point velocity that should - in theory - not be an issue.

Is this a 3DS Max problem or a corona one=#

Kind regards,
Jonathan
