Missing Point Velocity (point.v) in collision VDB

Recommended Posts

Trying to set up a simple VDB collision with rotating 'fan' geometry. My issue is I am missing point velocity in my VDBFromPolygons SOP. No point.v available under Surface Attributes. What is the simplest way to resolve this?

Its missing because you dont have the 'v' attribute on the incoming geometry.
