I FIXED THE ISSUE!
Admins: If pos
I'm just posting this here in case anyone is interested or if anyone else has the same issue in the future.
Problem:
Code:
<number> degenerate faces
Identifying the degenerate brush:
Finding the map version where the lighting first disappeared.
Looked what was different between that version and the previous version.
I saw that I had added some cylinders (but made from arches).
The arch wall width was set to a higher value than the size of the arch.
Solution:
Remaking this with a proper wall width fixed my issue.
