With the help of this fix, shadows on objects that are used to create interiors will disappear: walls, ceiling, door and window openings. I attached a screenshot of the result in CR-MP above to the topic. This fix will only work on servers with a mod pack.
Inside the archive, I attached the installation instructions (I also attached the topic in the topic, but suddenly the administration considers it to be advertising) The author of this fix is exclusively EgasVegas ( vk.com/egasvegas )
//UPD 2020 many do not understand how to install this fix into their assembly without a mod pack. you just need to open the SAMP.img file in the SAMP folder of your build of the game and replace the standard files in it with the files from this fix.
