For my own use only, I decompiled bigcity (NOT my own map. Created by Bigwig) and added a little airport.
Whenever I compile the map and run it, everything is fine except for the area surrounding the airport where the brushes turn black.
It appears to be some sort of a lighting issue because certain angles show the textures fine.
Here is an angle where it appears the way it should:
I haven’t used hammer in quite a while. There aren’t any leaks to my knowledge and the area is inside a viscluster I made separate from all the main one.
I’m probably making a stupid error, forgive me
As usual, all help is greatly appreciated.
