why my question is marked as answered and I cannot uncheck it? The answers sounds like the question was not even readed, no offense.
As I said, it’s not a problem of lightmaps. The shadow resolutions are correct, they even worked 1 day ago. It just stopped working in every project, including new ones… and it happens all across the engine when it wasnt happening.
I even tried reinstalling the engine, and it still does not work. Using the same (exactly the same) project in other machine, it works ok, so I think I will reinstall windows and then come here and tell if that worked.
