Ground Environment is a set of replacement textures for the ground, providing much better clarity and definition than with the default textures. It's a big improvement over the default textures, mostly from 3000' AGL and up. The Pro version includes the ability to color the textures for various weather (blue tones for OVC skies). Plus, you can customize the night textures for brighter lighting or color tones. Pro includes sky textures as well that can be customized or autogenerated like the ground textures.Active Sky Advanced does not come with any textures, and only Ground Environment includes replacement grounds.
