Hello. If I have a ball and I remove a cube out of it, properly offset so 
that the result is a half-ball, then merely retexturing a sphere (the 
surface of a ball) can't get you in any way to the surface of a 
half-ball, because the surface of a half-ball isn't a half-sphere or 
any subset of a sphere. What's missing is a disc (filled circle) put 
exactly where the half-ball was cut, in order to close it.
