Some problem about RG Trapcode particular bounce

Question

Hi there,I am using version 4.1.1 of Particular and I have a problem with the Bounce mode.I use a solid as a wall and set the Collision events to kill, wall mode is Laye Size ,but when I move the wall away, the particles that were supposed to be killed reappear. It seems like they were not killed but just hidden. How can I make the particles really be killed? Or how can I prevent them from reappearing when I move the wall?

I've been able to replicate this and it's strange. It resets with each of the interaction types. I do know that Particular can be a bit "delicate" about the order of elements added, so I wonder if it recalculates each particle per frame. (I did find an old reddit post with someone having the same issue but no reply - so we're not alone).

If it is a limitation of the physics model, then I think you'll have to fake it, maybe use a solid, hidden layer as an alpha matte for the particles when they hit the wall.
