You can search these mods in the mod section in the main menu of both Fallout 4 and Skyrim, respectively. Do note that this list only includes visual mods, such as lighting, weather, textures all across the board, animations, and additions (such as foliage). I compiled the best visual mods for both games (I've been modding for quite a bit, perhaps some of you remember my Skyrim post a while back). No incompatibilities with your existing (or new) mods load order. However, do keep in mind that any mods disables achievements. These games can REALLY look a lot better with the right mods. Since both Skyrim and Fo4 have had mod support for a while now, it's completely understandable that a lot of people can miss on some great visual mods because they just can't find them, or don't know about them. So, with both Skyrim and Fallout 4 having their Xbox One X patches today, I saw quite a bit of people overwhelmed by the amount of available mods.
