Make switchable light... (Patreon)

Let this post be like the answer to all requests to make the lights on the map switched off. Unfortunately, the Source Engine is totally outdated and it is very bad at it. Here is an example of what artifacts appear just on a small map, I fought with a bunch of similar incomprehensible black squares on the apartment map back in 2015 (map in the workshop). For this reason, I never want to mess with it again.
