Summary

hello.
I have a problem using the Niagara system.
When I render my project using the Niagara system, an error occurs in which the brightness of the space flickers.
Any idea how to fix this?
This error does not occur when playing back in the level sequence before rendering.
However, if the Niagara effect occurs in a project for a long time, there is a problem in which the screen brightness gradually becomes darker. Could this have something to do with it?
Turning game settings on/off was not a solution.

Steps to Reproduce

1. I created a similar effect by referring to this tutorial.
   https://www.youtube.com/watch?v=ziwNVtOyKSU&list=LL&index=40
   2.Initialize mesh reproduction sprite was used to connect the skeletal mesh.
2. The error described in ‘Summary’ occurred. Fewer errors occurred in effects where step 2 was not performed. Anyway, errors occur in both cases.

Expected Result

I wanted it to be rendered as it appears in the viewport.

Observed Result

-The brightness of the space flickers in the rendered result.
-If you leave the effect on for a long time, the screen will gradually get darker.

Platform(s)

unreal engine 5.2

Hi Seo,

This sounds like a problem with auto exposure. (The cinematic camera has different exposure settings than game camera?)

You can control this with a post-process volume. (Enable infinite extent on the volume to apply it to the entire level)

You can start troubleshooting by setting the Min and Max Brightness to 1

It was resolved at once.
thank you so much!

Oh, no, it’s not resolved. The same problem is still repeated. I’m crying

Hi again Seo,

Try experimenting with the ‘Use Exposure Logic’ bool in the Environment Light Rig, or try using the Lumen Exposure Manager.
