Hey guys! I have a scene with a flip tank a sphere above it and I am trying to get certain particles inside the tank to move towards the sphere. As an example, I want to get all the particles inside the tank that have an Y position higher than 3 to move towards the sphere. I managed to get the attraction with popattract and popdrag, but all the particles move towards my target if I use only these nodes. I was wondering if there is a way to iterate through the particles position and make just the particles that meet the requirements be affected by the attraction force.

Thank you in advance!!
