If I wanted to spawn particles from and based on the velocity of an objects points what would be my approach to this? I'm assuming need to use an attribute vop before passing it to the pop network… but my mind is a bit dead to houdini at the moment, just need someone to point me in the right direction if possible. Really appreciate any help provided!

I don't know that what do you want the velocity do for generating particles. I guess assume you want more particles from point with higher velocity. So this is what I would do:

pointvop (bind v length to speed attr) + pointreplicate (generate from attr on and speed attr in it)
and also a volume from velocity to use as particle advect by volume source.

a simple setup

Hey cheers for that, it's definitely a starting point for what I'm trying to achieve (which is basically have stuff emit from certain points on an object when its moving fast).
