Issue with Exposure on UE 5.6

Hi there folks!

I am here looking for your wisdom because I recently migrated my project to UE 5.6 and I have been getting an issue with the exposure of interior cameras and I was hoping to know if anyone else is facing this issue and how to solve it.

This is the issue. I get into my interior camera and first the exposure is as it should be but then it starts to get brighter and brighter.

and then, as it was a bucle, the exposure returns as it should be, like in the first picture and starts all over again.

I am working with physical exposure camera and lighting with Sky creator (PPV inside sky creator turned off).

Sun Intensity 100,000 lux to match RL

Inside PPV i got:

{
“Tagged”: [
[
“Settings.AutoExposureMethod”,
“AEM_Manual”
],
[
“Settings.AutoExposureBias”,
“0.000000”

[

[

[

[

[
“Settings.HistogramLogMin”,
“-10.000000”
],
[
“Settings.HistogramLogMax”,
“20.000000”
]
]
}

My camera settings for interiors are:

{
“Tagged”: [
[
“PostProcessSettings.CameraShutterSpeed”,
“80.000000”
],
[
“PostProcessSettings.CameraISO”,
“400.000000”
],
[
“PostProcessSettings.DepthOfFieldFstop”,
“5.600000”
],
[
“PostProcessSettings.DepthOfFieldMinFstop”,
“1.200000”
],
[
“PostProcessSettings.DepthOfFieldBladeCount”,
“5”
]
]
}

Any idea what could be causing this issue? I am willing to hear you thoughs :slight_smile:

Regards!

If exposure is increasing during gameplay, it sounds like you have Auto Exposure still enabled. If you’ve turned it off somewhere, it might still be on somewhere else. Post Process volumes and cameras will be competing with each other and you can try bumping up the priority of your camera or wherever you are turning off Auto Exposure.

I’m not familiar with Sky Creator, so I don’t know what else it is doing. Maybe it is moving clouds across the sky and changing the sun brightness. The exposure cycling up and down sounds bizarre. I would be interested in seeing a video of that. This might be one of those cases where you duplicate the level and start chopping out Blueprints, PPVs, and Cameras aggressively to see who is doing this.
