Hey,
I'm not quite sure what you mean. For example, in tyFlow the particle groups do affect collisions. If you put particles from one event into simulation group 1, and particles from another event into simulation group 2, and then merge those particles together, they won't collide with each other. You can do the same thing with PhysX colliders....particles in simulation group 1 won't collide with PhysX colliders in simulation group 2, but particles in group 1|2 will collide with those in group 2, etc.
It's a bitmask with overlap/include/exclude settings.
