This update adjusts a lot of settings for Lumen Global Illumination and Reflections. We've carefully tuned some default engine settings which should fix a lot of issues with existing maps and things being a bit too dark. There is now a significant amount of indoor lighting to prevent things from over-darkening along with some boosting to texture colors.
There's also an important fix for auto-exposure settings which weren't originally tuned very well for a competitive shooter. These settings are what adjust the exposure of your eyes as you walk into light areas vs dark areas. We've now overridden the entire auto-exposure system in the engine so that it performs as intended. The same goes for workshop maps which should inherit all of these settings by default.
