[Sidefx-houdini-list] Grabbing velocity from dops

I'm fairly new to actually using dops.. so excuse me if this is obvious.
I've got a whole bunch of rbd objects doing their thing, created from
groups as you do. I'm pulling them back into sops with an object merge
and /obj/dopnet:chunks*/Geometry, as I think is the way you should do.
I want to render them with motion blur. I don't want to use a trail sop
because they're pretty heavy and I can see there is a value "vel" for
each object in the Position in dops. How would I go about getting this
onto my geometry as a point attribute? Do I need to stamp around an
expression per group or something? There must be an easy way for this...
