Hello Houdini Users,
I am trying to figure out why I'm not getting any v (velocity) attribute on my moving geometry. Any thoughts?

you weren't creating a velocity attribute anywhere. heres a fixed version. just added a trail sop set to compute velocity. you have to tell the points what their velocity is, they don't just know.

Thanks zdimaria. I knew there was something I was over looking.
