Particle Systems spawned via a blueprint are not generating collision. The same system will generate collision if placed directly in level.

1. Open attached GunEffects.uproject or Smaller Particle_Collision.uproject
2. PIE
3. Right Click to fire weapon at floor or wall
4. Press "K" on the Keyboard

RESULTS: Weapon fired from gun has not particle collision for debris, but the same effect placed in level and activated (by pressing K) does (In Particle_Collision, Right most Particle System does not have collision)

EXPECTED: Both systems should have the same collision (In Particle_Collision, Right most Particle System should have collision)
