We have been developing a new map for our game, and one of our team members developed and put the map together on their own machine. But, when he pushed the map and all the assets using Perforce, a few of our other team members have been getting a completely different map, where the entirety of the map is extremely more dark than the original.
For instance, this is what the map looks like normally, on the computer of the creator:
Maybe some of your team members activated light propagation volumes while others didn’t? It can only be set by editing the consoleVariables.ini (C:\Program Files\Epic Games\4.7\Engine\Config). Using it disables the standard global illumination, which would explain why everything is darker for some. Not using it prevents them from see indirect lighting from the LVP, which could also be the problem.
It’s a shot in the dark, but it might help to check the consoleVariables.ini of everyone and see if there’s a difference between them.
It turns out, it was actually ShadowQuality. In our development version of the game, we have test controls to change the render settings of the game, and for the longest time, some of us had ShadowQuality set to 3. When we set it to 0, our issue was resolved.
