A free mod for Witcher 3, by ScoutBr0.
There are times when you want your characters to be in a dark environment, like while you're in a dungeon or a cave. The problem is, when you try to remove the light, it all or most of the time, doesn't work and your game ends up with a black screen or your characters being unable to move.
This is why this mod is so great, it removes the light and dark areas from the game while keeping the cutscenes as is. It's really easy to install and use, even for people that don't know how to install and use mods.
If you don't know how to install and use mods, don't worry, you can just follow the steps in the installation guide.
