That is how you should map the sphere, this is not flipped horizontal.. this is true mirror image of the scene.. as it would be after you convert it from a silver ball..reflection
after you put this on the sphere everything would works right..so the texts etc... do not change the UV_Scale that not only flip the map horizontal but also change the directions..and that is not a mirror image
