Developer Notes

The particle system specified does not provide any events that I could generate, however, if I use Events_Test and the Death event, it works just fine in the level script.


Events like OnParticleSpawn, OnParticleCollide, and OnParticleDeath are not triggering in the level blueprint.

Steps to Reproduce

1. Open QA Game Editor
2. Place ParticleSystem'/Game/QA_Assets/Particles/Systems/Collision_Events_Test.Collision_Events_Test' into the level such that it collides with the floor
3. In the Level Blueprint, Add "OnParticleSpawn" "OnParticleCollide" and "OnParticleDeath" nodes which reference the added Particle system.
4. Connect all the nodes to a Print String node
5. Compile and Save
6. PIE

RESULTS: No Print String Occurs

EXPECTED: Every time a Particle Spawns, Collides or Dies the Print String should happen.
