Hello, after i bake my test level where outside has day but underground second landscape radiates some sort of light through because of Skylight(static mode). I even added some sort of massive ghostbox to block light from below but without any use. It affects movable objects that receives weird radiating light, on last picture i raised test mannequin up from ground and no bleed anymore. Walls are same that moving close to walls then character will receive that glow. Third picture is my attempt to make huge ghostbox(statif of course) to block bake light without success. One solution that works is just removing skylight but then i loose mild light bakes where i would want.
EDIT: Found it, Lightmass Importance Volume ended too soon and i resized little bit of more on Z axis and it fixed this issue. Leaving post here if someone will get similar issue but leaves lightmass importance volume size unnoticed.
