UPDATE: This issue started happening after Unreal crashed. After I completely reinstalled the engine, all particles are spawning again. Nothing is being suppressed anymore. Heh, I’m sure that’s the answer you wanted to hear. Sorry. :<
I am confused by this message in the output log:
LogParticles:Warning: Particle Notify: Anim tried to spawn infinitely looping particle system . Spawning suppressed.
^^Certain particle effects will cause this message to appear and the effect won’t spawn. This sounds like the engine is preventing an effect from spawning if the loops are set to 0.
But that can’t be why, because some effects that cause this message to appear have all their emitters set to 1 loop. Not only that, but I can create a new particle system which defaults to 0 loops in the required module and the animation will spawn it just fine. I don’t actually know why certain effects cause this “spawning suppressed” message to appear.
^^Here is an example of what I’m seeing. The emitter loops are set to 1 in the not_looping notify. The emitter loops are set to 0 in the looping notify. Yet the non looping one is suppressed while the looping one plays.
