After building lighting most of objects become very bright with black spots

Hi!

I’m working on spaceport on alien planet. Everything was going perfect, but when i built lightning most of objects become very bright with black spots.

Some objects are very bright just partially.

Any ideas why this happened?

By the look on that three in screenshot 1 I’d say the lightmap resolution is too low. Have you tried increasing it?

Yes. I increased it to 256 and nothing changed.
