Hey everyone!
I have a simple but annoying issue: when I switch from my Third Person camera to a camera on another Blueprint (laptop) using Set View Target, the image instantly becomes darker.
Both cameras have:
Exactly the same settings (copy-pasted)
Same Auto Exposure (Manual)
Same Post Process Settings
Same lighting in the scene
I’ve tried:
Disabling Auto Exposure globally
Forcing Exposure Compensation
Adding Post Process Component
Nothing works! The laptop view stays darker than the Third Person view.
Any idea what could cause this? It’s like Unreal recalculates something when changing View Target…
Thanks!
Hi @Defedarax1,
Yeah, this is very odd. It also appears to me like an auto-exposure issue, which is odd given that you appear to be controlling that.
Try enabling this view mode and compare the histogram results between the two cameras. That should let you know if there is any exposure change.

The solution for this was to create a Post Process Volume with these parameters:
Metering Mode set to Manual
Exposure Compensation adjusted to get the right lighting
Apply Physically Based Camera Defaults set to False
This fixed the black screen problem, but then I had a new issue: now I was getting a light flash when switching cameras!
And the final solution was to set the laptop cameras to Auto Exposure Histogram. That way no more flash and the lighting stays perfect!
Thanks 
!
