Hi Alex,

are your particles flying very fast ?
If so you could increase the oversampling on the pop-network but that slows
down the whole simulation.
Another thing what you could play with on the collision pop would be the
collision tolerance parameter.
That parameter defines 'Distance from geometry at which particle is
considered to have collided'
