WebJun 30, 2024 · A bunch of research has led me to a very crucial thing used in PS2 games, Phong shade or Gouraud Shading, though I think Phong best suits my purpose. Surprisingly enough games that relied on shadows in PS2 were actually Unlit levels, infact most games from this era were ‘Unlit’, unless it’s a Quake 3 type game (graphically).
