Event Receiver Collision Issue

Hi guys,

I’m experiencing some collision issues working with particle systems.
Basically, I spawn some chunks and when they collide with the ground I generate an event which spawn some smaller debris from them. Untill here everything’s working perfectly.
The problem is that I’d like to let the new particles generated as “event receiver” to collide with the ground as well, and unfortunately it doesn’t work. They fall through it and don’t collide with anything else.

I’ve tried to put a blocking volume but it doesn’t work too.

Does anybody have some ideas to fix this?

Thank you!
