The problem is when the ribbon is coming from behind of other player. The other player can not see it. When the ribbon is in front the other player, then he can see it. I think it could be some optimization setting problem. (some culling settings or something like that). I was looking in the character settings, in the camera setting, in the project settings, in the particle system settings, but at the moment i found nothing to fix it. In this video you can see what is happening: And (just in case) i think i have the material and the particle system is configured well. ![1](https://d3kjluh73b9h9o.cloudfront.net/original/4X/9/3/d/93d201425b1cd11dd408b83f8ad90cb8af980120.png) ![3](https://d3kjluh73b9h9o.cloudfront.net/original/4X/b/7/1/b71c28ca61c239ac826026631fc90cba87e52457.png) ![2](https://d3kjluh73b9h9o.cloudfront.net/original/4X/7/6/f/76f5f503a7eb392eef05677d1a124bfa3d5334c4.png) How can i fix it? Thank you so much!! ---

Hey there @Ivan3z! When I see an issue like this it’s either due to net relevancy or the visual culling. In your case, I’m banking on the fact that because it’s actually showing when close to in view it’s actually bounding box related. Since (GPU)particles need to be on screen to be rendered, they are handled by a bounding box and if outside of it do not render at all as a performance measure. You might be able to increase the bounding box to force them to render for all in the area. Give that a try and let me know how it goes! > [@Niagara Particles Dissapear When NOT in Camera View](https://forums.unrealengine.com/t/niagara-particles-dissapear-when-not-in-camera-view/263064/): > > When using the camera in sequencer along with niagara particles - I notice that if the emitter isn’t in the view of the camera then the particles disappear. This is the same for when the emitter comes into view of the camera, suddenly the particles start working again. How might I have emitter continuously spawn without needing to be within the camera view? ---
