I've been making maps in source sdk, and If I'm not mistaken, if UE4 is as easy as I think when it comes to lighting and mapping, could we get an option to change mood of the day on already existing tracks?
For example, Yuri could have an option to be played at Evening, dusk, night and full day, blue sky. I think that copy pasting the map and edit it to change lights and skytexture into night isn't as much of a work, and it could give a lot to the game
of course, priorities aside, I don't think it takes much hours to make. . unless we're talking about sandstorms.
