I’ve been working on my project since UE 4.9 (mostly evenings, sometimes weekends). Yesterday I decided to rebuild lighting (UE 4.12.5; re-built lighting several times using this current version). After I did it, lightmaps became completely broken:
This is how it used to look like (from 4.11.2 as I don’t think I ever took “aerial” screenshots in 4.12.x):
I did not change anything, it just happened out of the blue. I tried clearing Intermediate/Saved/DerivedCache, clearing old lightmaps, changing lightmaps resolutions, lightmaps atlas resolution - nothing work. My project is now f#$ked.
Has anyone experienced the same kind of issue ?
If so, how did you fix it ?
