Thank you for the reply. It’s much appreciated.
I had auto-exposure unchecked in the project settings and metering mode unchecked in the post-processing volume but I had somehow missed the Min/Max Brightness settings. That was it. In UE2 there was a simple setting for Ambient Brightness. Even though it washed out the well lit areas it was good for brightening areas that were very dark. Min Brightness seems to do that but no matter what I set the Speed Up/Down settings to there is always a slight delay. I haven’t built lighting yet and tried in game but in the editor window I can’t get it to behave the way I want. I will play around more. Thanks again for the information. I have a lot to learn and you have helped me with that.
Edit: Nevermind about the slight delay. I got it.
