I’m using 4.16.3 version and I have a problem with bulding lightning. I have over 4000 unbuilt objects on my scene, and every time when I try to build lighting, I get errors:
Map check finds some errors!
Wordl_Settings1 Maps neeed lightining rebuilt!
That’s all and I don;t know what should I do. Can you give me some advise?
i get the same error when i try and do a full map build with unbuilt lighting. a full build first checks the entire map and finds unbuilt objects. it then generates the error. then, because of process order, it builds the lighting and everything should be fine. if you do a lightmaps only build you shouldn’t get that error. i wouldn’t worry about it though.
unless you removed the default material on them then they should have something. you could try making a basic material and see if it fixes the issue. it’s also possible it has something to do with the wardrobe warning.

i would start by making a new level, putting a few basic things in it, and trying to build that. keep going until something breaks. if it doesn’t work from the beginning then try a new project.
I’m going to throw this out there, because it works. You just need to have a PC and a Mac, or a Mac running Windows via Bootcamp (I suppose an emulator might work, I keep ten feet or more away from them myself).
All you do is, copy the project to the other system from where the lighting won’t build. Boot up the project on the alternate system, run the lighting build, and voila’, it works - you hope. Copy said project back to the system you’re creating on, and your lighting is not only built, but will be buildable again on the system it broke on before you did the OS switcher-roo.
I don’t question why this works, I just know it’s saved me countless hours and leagues of frustration I used to face when the lighting breaks. Which it always does at some point it seems. Usually, near the end when lighting is most complex and the game is almost done. This actually just happened again last night. Worked the switcher-roo = Hi, Murphy. Bye, Murphy.
