Jonathan Cooper, who is an animator at Naughty Dog talked a bit about the difficulties that the developers faced while rendering hair and how this could be fixed in the future.
“A major reason so many last-gen characters sported crew cuts was we couldn’t do hair easily. I expect much more hairstyles this generation,” he tweeted. He further stated the reasons behind the same. “Primarily because engines couldn’t support realistic lighting on alpha (see-through) textures, not to mention physics on long hair.”
He further revealed that new technologies are incoming that will help them create realistic characters. “There are more technologies incoming that will release us from the homogenisation of game characters,” he tweeted.
Uncharted 4 has a 2015 release.
