I’m using UE 4.8.3 and recently have faced a problem which seems to be related to auto exposure.
We have a project under version control and on original computer a map from the project is brightly lit. Unfortunately, when I checkout the project on my machine, the map is very dark. Why I do think the problem is related to auto exposure: if I uncheck the setting on the first computer, the map starts looking dark exactly the same way as it’s looking on mine (no matter is the setting checked or not).
I can’t really offer an answer, but I did see this when messing around a with levels a while ago. My PC was fine, my Mac was much, much darker.
I temporarily wrote a little script to adjust the AutoExposure levels on Mac which always felt a bit hacky, but it worked.
Later, I created a couple of new maps and the problem just… solve itself. I really don’t know what it was that changed, but it was not a hardware / platform problem, it was something in the umap but I really don’t know what I’m afraid. I’ve tried looking for answers since, just out of interest but yet to find anything conclusive.
