Title: particle events - stick, emit & disappear on collision?

Hi,

Wondered if someone could help me stick a newly emitted particle to a surface.
I have particle rain falling and hitting a grid floor obstacle. When the particles hit, I want them to Disappear & Emit a new static Particle Type on the surface.

If I use Emit and Disappear, the new particle stays where the Rain particle was the frame before the Collision, ie. just above the surface.

If I increase the Collision Accuracy (even a silly amount) it will improve a, but not a lot.
If I use Y=0 as the event insted of a floor obstacle, then the new particle is born just underneath Y=0

I tried to use two Events, one to stick to the surface then another to Emit & Disappear if the Speed=0, but the original particle just stuck.

We have managed to create a small Particle Event Script to place the Rain Particle at 0, but haven't figured out how to emit the new particle with scripting yet.

Is anyone familiar with another workflow/workaround or Particle Event Script to help out?

Many thanks,

Adam.
