Well I would have to say the spheres look quite ugly. But is there any chance of anyone having a sphere that does look ugly for a looped texture?
I am making moons and I can’t afford a moon to have stretched textures.
Install Blender and export a standard UV sphere. They look quite nice. Even add a smoothing or subsurface modifier if you want to make it look less polygonised.
You can export the UV map then, which is an added bonus.
Edit: Don’t forget to ‘Apply’ the modifier before export.
If UV map doesnt want to generate, you need to add a material first. There are hundreds of Tuts on this, and its worth learning.
