Weird lighting issue with night/day system

This issue only occurs typically when the time is set to “night” and you connect to the server.

Not all the time though, it’s just random.

Part of the map becomes completely black, and i don’t know why.

Any ideas?

Compiling map in fast vis/rad causes such things.

So it all has to do with the map?

Anything to fix it besides changing the map?

Does mat_fullbright change anything, or are they just missing/hidden?

Instead of using a as the max-dark light-setting in that map, use b… Some maps don’t have light environments or have other issues which can cause that… If you’re low on memory then E_OUTOFMEMORY will be displayed in console but the textures will be black regardless of light setting…

If b isn’t dark enough, you can use fog to simulate darkness.

Was the map compiled with named light_environment?

If I remember correctly this can happen if the map is compiled correctly for day/night, but there is no ambient light so certain things will go black and some wont.

Is it because of the map, and it can’t really be fixeD?

Not without a recompile. If you do this you would have to know what you do.
