I was making an eyeball, at first i thought i didn't need the entire sphere, so i cut it in half. Now after finished weight painting and everything, the character is a humanoid, and it has quite a large eyes, i realized i needed the entire sphere, or atleast another quarter of it so that it'll not look weird.
In edit mode:
Select the half of the sphere then Shift D then R Z 90
To merge vertices select both halves and press m > By Distance
$\begingroup$ you probably mean R, Z, 90, otherwise you will rotate depending on your view orientation $\endgroup$ Nov 20, 2022 at 17:44
