Spawn and collision

[nobo]

Hello,


I'm a new Tyflow User.
I try to make a simulation with a ball in a tube.
I want every collision with a boll make two child particule and delete parent.
It's ok, for the first hit, but i can't do it for the second et next hits.

i have use physX shape, physX Collision and spawn.
Have you got an idea to do this?

thanks
best regards
Bruno
