In vanilla fallout 4, there are over 600 ambient blue lights placed in the worldspace. These mostly revolve around the Fort Hagan area and serve to offer light in the nighttime as a result of glowing mushrooms on trees. While some might like the atmosphere this provides, they generally look ridiculous, especially considering that not all of the forest fungus even has light markers to imply they glow. So in the end, you get this jarring look with random blue light-up splotches in your world, along with oddly dark patches where you can only see the glowmap of the mushrooms shimmering. Using this mod will set all ambient blue fungus lights in the Commonwealth to "initially disabled". This means it still exists in your game, but you can't see it - the safest way to remove an object. Along with removing the hundreds of ambient lights, this mod also removes glow maps from the tree mushrooms (optional file without this addition).

Should be compatible with everything. Precombines and previs untouched.
