Can't see the particles in matinee.

Ok so I’m not really sure whats wrong with my scene, But I created a scene with some particles taken from the effects demo, and scattered them along my cave.Then i did set up a matinee with an animated camera.

My camera is going through the entrance of a cave to the end of it. It’s all perfect in the editor, however when i try to render matinee i see only the the particle instances that are in the beginning, at the entrance.

All the rest of the scene appears empty (no particles at all) . When i just scroll through matinee, or just play it, it’s all good. But once i record a matinee some of the particles just disappear. When i play the level in the editor it’s even worse, because most of the particles are not visible at all.

I did try to play with maxParticlesPerFrame cound for both CPU and GPU particles. I made sure that my particles don’t reach the count limits. I did try to make a fixed bounds but nothing seems to be working at all.

But since it doesn’t happen to the fire for example, I’m assuming something is wrong with those assets from effects scene, or I’m doing something wrong.

Assets I’m using are P_Blizzard and P_SnowFlare

And here’s the screenshot

Would appreciate any suggestions,

Hey Tony,

I have a few questions that will help me understand and narrow down the cause of the issue.

  • Are you triggering your Matinee to play through blueprints?
  • Are you manually placing the Particle System in the level, or are you triggering it through a blueprint event?
  • Have you changed the detail mode of your Particle effect within the details panel for the particles you are experiencing issues with?

Assuming you are using Blueprints to drive the matinee, what could be happening here is that you have no player triggering the event to spawn the particle effect. Let me know if you discover any new information or if you have further questions.


Hey Andrew,

I’m using blueprints to activate the matinee thats right, Particle systems are places manualy along the level and i did try to play with detail level (it was on low initially) but it didnt change anything by the end. Always the same effect, i see some particles at the beginnig of matinee when i record a movie and closer to the end they are just gone.

Hey gonzamancg,

I just tested the particle systems you mentioned in a blank test project and a new matinee sequence, and was unable to see the issue you are reporting.

Instead of activating the Matinee recording through blueprints, there are settings within the actor itself that provide control over playback.

Matinee - Details

Try using this option instead so you can cut straight to the recording as soon as the level is played. Let me know if this worked for you, or if you need further suggestions.


Ok thank you I will try it out. Probably it’s just something is wrong in my scene.
