In vanilla Fallout 4, the game utilizes cubemaps on many objects to sell the illusion of realistic metals and reflections. These default cubemaps are a projection of Concord and it's surroundings. While nothing is inherintly wrong with the vanilla cubemaps, it's recognizable location and deeply contrasted appearance can look dissatisfactory at times. Natural Cubemaps ammends this by using a neutral and simple projection of an arid field and pale blue sky. While tastes are subjective, Natural Cubemaps offers a fresh yet fitting look for a handful of vanilla cubemaps.
