Having trouble with getting event modules to work correctly in Particle System functions

So you need a few things for events to work.

  1. In the larger debris system, you need to put an event generator. Inside of that event generator, you’ll need to set the Type (to spawn, it sounds like you need)
  2. In the Event Generator, give the event a custom name (ex. SpawnSand)
  3. Add an eventReceiver Spawn module to your fine sand emitter.
  4. Be sure that you set the event generator type to spawn.
  5. Set the eventReceiver Spawn spawn count to some value
  6. Set the source event name to a custom name (ex. SpawnSand, needs to be the same as above)

That should do it!

Let me know if you need any more assistance.
