I've bean reading this thread and it's blown me away. One think I would like to know is this talk about decals! what are they in video game terms? are decals for the use of eyes used commonly in japanese/stylised games?
Eyes don't look decaled. They look the head is multitextured, and then they do the eye pass, there is no Z depth test, so it draws over the hair. Haven't played a Zelda game since '64. :(
