A nice addition to Vibrant Auroras (currently in STEP if I'm not imstaken). While VA changed the meshes, this mod changes the textures. They work nice together.
This mod is
doubling the dimensions and increasing the detail and variation. Since the original textures were small, there should be little performance impact of these new textures. They are still only 700 KB each in size. Therefore, this mod should be usable on anyone's setup.
