Mesh Particle Not Spawning Child Emitters from Collision

Hi guys, I have an issue with a Mesh particle I created. It’s a missile that’s intended to collide with a vehicle used from the free vehicle demo. Once it collides with it, I used an EventReceiver Spawn to spawn an explosion. It collides fine in the editor and whenever I press Start Level in Cascade but once I Play or Simulate, the missile goes right through. Any thoughts on some collision settings I’m missing?
Here are some images to help:

Alright, I solved it. I unchecked the Collide Only If Visible option in the Collision Module and turned up the amount for Max Collision Distance. I also unchecked the First Time Only option inside the Event Generator of my missile.
