So, Im working on a scene and for some reasons there are really weird glitches on the walls of the apartment. The UV is clean and I cranked up the lightmap settings to 2048. But it doesnt look likes the problem are shadows. I dont know what it is actually. Take a look at the picture and if any one have an idea that would be great. If you need any other information ask away. I need this fixed asap.
Thanks for the help!
