Can't build Light in specific map

Hi,

I tried to build light, but every time it builds only the Navigation and not the light in my Level, in the same Project with an other Level, it works. If i click on “Build light only” It does the same, only in this map, in each other it works. What do i wrong. I checked the worldsettings, I have no Idea. Can somebody help me?

Thanks. Jojii

Same Here.

Okay, I went to world settings and turned off, precomputed visibility, and Force No Precomputed Lighting. Then building worked as normal. Hope this solves the problem for you!
