4.15 colors drastically different

colors in 4.15 ^ vs. colors in 4.14.3. the problem seems to be caused primarily by the skylight and emissive colors. i’m seeing others having issues with the tonemapper in 4.15. is this fixable?

Having the exact same problem here. Blues became purples when emissive power is multiplied. Happened after the upgrade to 4.15. I think it has to do with the new Tonemapper but I’m not liking the new look. Can’t keep my emissives blue without them becoming washed out.

i’ve played with the post process volume settings, and tried migrating to see if it was just the upgraded project not translating. no luck

from the release notes: The filmic tonemapper will look different than the tonemapper in previous versions of the engine. You can switch the tonemapper back by adding r.TonemapperFilm=0 to the SystemSettings section of your project’s DefaultEngine.ini. We intend to remove the old tonemapper in a future version of the engine.
