Painter, who hails from Norfolk, Virginia, is entering his senior season. He will have two years to play one season but could receive a waiver to play his final year in 2012-2013 due to his personal issues.
The 6-foot-9, 231-pounder averaged 6.4 points and 4.3 rebounds this past season as the Wolfpack's sixth man.
State will add back 7-foot-1 redshirt junior Jordan Vandenberg, who missed the 2011-2012 season with a shoulder injury. The Wolfpack is also in the mix with five-star recruit Amile Jefferson, and junior college big man Andrew Young.
