Hi people…glad to be here with my first post.
I have a changing group of points with point numbers changing since non group points get deleted. I have a custom attribute called orig_point which holds the original geometry point. I feed the group of points into a pop network and I am trying to prevent particles to be emitted from the same orig_point if another particle has already been born from it.

I tried using a vop pop with a for loop to go through all ptnum's and see if the orig_point value in the current evaluated particle exists in any other particle…if it does…delete the current particle so I only have 1 particle per original source geometry point. ….I have had no luck with this so I was hoping someone could help me out on this.

I'm attaching an example file.
