I was trying to put a map of Kerbin onto a quad sphere (a sphere made from a subdivided cube), but there is an issue, which I think is quite apparent. Now, I did figure out that it has to do with how U is assigned to each vertex, and that U = 0 and U = 1 are not on the same vertices. I have no idea whether it is possible to fix this, or if a vertex can even have multiple UV coordinates, but any help would be greatly appreciated.
