POPVOP affecting outside defined group... why?

Hi there.

I have a pop net, inside I define a group of particles, “seek”, and I apply to them a “Pop Vop” to apply a noise to their velocity, the effect is the one I'm looking for, but then I put thos particles in a different group “seeking”, and with a “POP Wrangle” I remove the points inside the group “seeking” from the group “seek”, after that there is a POP Steer Seek to make the particles go after a shape, and it works except the “Turbulent Noise” inside the “POP VOP” is still affecting the particles, even when the “POP VOP” should be affecting just the group “seek”.

I'm a bit desperate to understand this, some ideas please?

I tried also to detect inside the “POP VOP” if the particles are inside the group “seek” but I can't find a way to do that.

Thanks in advance!

P.D.: I posted the same question at OD Force, just in case you find this familiar, but no answers at the moment.

The first thing that comes to mind is that the Wrangle might be running over the wrong context and thus not actually removing them as expected. Check that you are running over points and not primitives.

Thanks for the idea, how can I check that?

I ask because there is no list to select points, primitives, etc…

But anyways, the wrangler is working because if I check the spreadsheet in the “POP Steer Seek” the group “seek”is marked as 0 in each point inside the group “seeking”

Is weird because in the “POP VOP” I apply a turbulent noise but I also add a bit of velocity to Y, so the particles raises up, and that addition is working correctly, it's activated while in the group “seek” and it's not affecting while in the group “seeking”, so it seems it's related to the Turbulent Noise because it keeps working even when the points don't belong to the designed group…

Cheers.
