I have a map with movable skylight.
When I open it, everything is OK, but when I load that level from blueprints (Load Stream Level), all shadows become darker than darkness itself.
I figured, that it’s somehow related to skylight mobility. If I change it in editor while playing to static (or station, doesn’t matter) and then back to movable, shadows are back to normal.
For now I have to use blueprint which parent is skylight, with movable setting preset.
I hope someone will notice that message.
