Niagara particles Culling if origin not on screen?

I have a Niagara system that spawns mannequin static meshes moving on the x axis.
In the video attached, if the origin of the Niagara system is within the screen, the Static meshes are visible. If I move the camera away from the origin of the Niagara system, all static meshes disappear.

Is this some kind of culling?

Is it possible to keep particles which are within the view, “Visible”?
Or a way to “attach” the origin of the system to the movement of the particles?

I am working on making a “crowded” area with a Niagara system, but if all static meshes disappear if the origin is out of view, thie sistem is unusable.

Thanks!
D.

It’s probably culled because the visibility bounds are too small. Increase the bounds on your emitter or system to fix this.

For those (Like me) where disabling culling was not a solution because first of all it kill performance by rendering every object all the time, and cause my engine to crash.

I set up a Blueprint with the Niagara particles.
In Niagara detail panel, go to the “Rendering” section → Occlusion Query Mode → chose “Always Disabled”.

It will disable culling only on this Niagara particle.

And you’ll have to drag n’ drop the Blueprint into your scene instead of a Niagara particle system.
