I tested other options ( at least those I know ) like exposure, bloom, saturation and they all seems to work.
I tried adding to directly to the camera’s post process but still nothing.
The problem seems project wide as it doesn’t work with any post process volume or in any level.
I might have accidently changed something somewhere…but I don’t know what.
P.S. - I don’t know if this is related, but my animation created in the sequencer got corrupted on the next load with the error in camera actor and the warning “NewObject was used instead of CreateDefaultSubobject during CDO construction.”
This might just be an internal unreal error and might be unrelated but I thought I will mention it just in case.
