Particles instability at boundary of particles with inverse mass = 0

Sound strange! would it be possible to take a look at your blueprint, as well as the code you're using to "grab" the particles? This method you describe (setting inverse masses to zero to pull particles around) sounds very similar to what the ObiContactGrabber utility component does, but so far I've been unable to reproduce any instabilities/jittering or similar behavior with it.

kind regards,

Thanks for your reply Jose. The fact that you can't reproduce the issue makes me think I need to investigate more on my end. I cannot share here unfortunately (apologies to all readers) as I am under NDA but I'll email you.

Meanwhile I managed to mitigate the issue by also setting the invRotationalMass to 0 for all the particles whose invMass I'm setting to 0. This stops the surrounding particles from shaking. If I now manage to take control of rotations, which shouldn't be hard, I'll be in a good place.
