Werrus Shaders was designed to bring subtlety to Minecraft’s night and darkness. It’s going to be really dark in Minecraft with this mod installed, but it will be very smooth, so that you will still see the shapes of the objects.
Again, it is perfect for those types of maps, where you like to play your creepy mini-games. The moon light will be your only source of light and it still depends on whether there will be no clouds in the sky. It is highly recommended to use this mod on high FPS.
