two events react to eachother

[hrohibil]

If ypu use Physx, they will react automatically. Just make sure  you have PhysX shape in both event.
As for further fracturing, when balls hit the wall, it's a little bit more tricky, bu this tutorial is great:

Thanks. 

I will look into it for sure.

Thanks

Just looked at the video. Thanks
But that did not provide me any info on my goal?
Again if i could use Surface test, collision or similar like in the video it would be awesome, but as mine is not scene geometry but particles from an event i can´t use any of the test conditions...
