Lighitng Problems

Lewis Taylor

Evening guys having a small issue here, where the geometry meets on the floor there is a visible lighting seem. Looks like each geo is lit interdependently. Not a pro at Unreal so any advice to fix this would be awesome. Cheers in advance.

Try setting the static lighting level scale in the world settings/lightmass to something low like 0.1

And here is a thread that covers this issue in more details:

I would not recommend to go too low on the static lighting level scale though since it really makes bake times explode while introducing several other issues. I have successfully fought this issue with those settings: production bake, indirect lighting quality between 4-6, indirect lighting smoothness between 0.75-0.85.
There have been several improvements to lightmass over the past updates as well so this issue should start to disappear with the mentioned settings
