Everything turned to green after rebuilding lighting

Hello, I’m having an issue I haven’t been able to solve, or find anyone else having the same issue. I have a city imported into Unreal Engine which looks great, but after I rebuild the lighting the entire model just goes green.

This is before I rebuild Lighting:

And this is after I rebuild Lighting:

The logs are only telling me that there are overlapping UV’s but would that cause the entire thing to go this green? I have no idea what else might be causing it. None of my lights even have a touch of green at all.

Any help or suggestions would be appreciated, thanks!

You have some green lines on the sidewalks.

Is it possible that you have tuned up their “emissive” value way up? Materials give out light too.

That’s just nav mesh for the citizens.

Are they still green when you “play” the game?

Can you isolate the problem? (make new level and move a bunch of assets there to build light)

is it the nav mesh? if you click P does it go away?
