Particles not appearing in packaged game

Even if I drag a particle into my level and see it going I still have this problem. It plays great in the Editor and Simulator but it’s just missing in the packaged game.

I tried everything:

-packaged to a new folder

-render visible CHECKED

-actor hidden in game is unchecked

-check the detail mode in LOD and set to high

-render in main pass is checked

The only weird thing I am doing is attaching the emitter to the Matinee camera. The emitter is spawning confetti and it’s attached right above the camera and snows down as the camera moves. It works and looks great in the simulator! How frustrating!!

Hello Jon,

Are the particles GPU-based? if so, are the bounds set up properly?
Maybe something is messed up in the particle LOD’s, resulting in no spawn.

Hi Jon,

Are you triggering your particle system with an event track in matinee, a separate event in blueprints, or is it on autoplay? Also how are you attaching the particle system?

they are not GPU particles… but yeah it seems like a LOD thing… I’ve tried conservative settings on the particles though… and still nothing…

When the player runs over a trigger box I set this all in motion…and I attach the particle to the Matinee Camera.

Hey johnbellini,

It looks like it could be an issue with the “SpawnEmitterAttached” node. I’ve entered UE-29018 in our system for this. Thank you for reporting this.

do you know another way to have the particles spawn to the HUD or something.? I want the Confetti to be “everywhere” as the camera moves during the cut scene.

Like for a 2D engine game I would put the particles on a zero parallax layer.

You could try “Spawn Emitter at Location”, do some math from the location of the camera, then attach. Or you could leave the emitter attached to the camera from the start (no need to spawn) and then just activate it when needed.
