Hello there,  
We need to tame some alembic motion blur here, but having some issues.  
Is there a way I’ve missed to change the velocity multiplier without VRayProxy ?

(image and test mesh attached).

(3) Basically, the only way to adjust velocity seems to be via VRayProxy, but VRayProxy ironically isn’t picking up/Rendering the velocityPV channel ?

(4) VRay renders the Alembic, but with WAYY exaggerated motion blur if just imported as Alembic.
