[Newbie] Missing Textures and BP_Sky_Sphere

So I’m new to the ark dev kit, and I’m trying to make a custom map. However, whenever I select “New Level” and select the “Default” template, there is no sky. BP_Sky_Sphere is there, but it’s just a plain white sky. As well as this, the textures for Dirt_Plane_NoHole are missing. Any ideas what’s going?
