Trying to map this to a basket ball but it always warps the lines.

if i remember correctly, the black lines on a basketball would need a different map.

Always ready for technical challenges!

This is a rough version (faked in photoshop) of how the map needs to be to correctly wrap on a sphere.

As you can see, there are further problems to be handled if you want total realism, for the texture on the ball shrinks at the poles, as does the black line.

If this is close enough, I'll leave it at that.
