Johan Lithvall is a character artist at Starbreeze who specialises in hair. Which sounds crazy, until you take a moment to appreciate just how much hair a modern video game character has, and how good it looks blowing in the breeze.
NVIDIA HairWorks is a cool and interesting piece of tech that already exists, but you probably never use it, because it absolutely kills performance (hi, Witcher 3). Still, development and progress continues, and here's you can do with version 1.1 of the tech when you don't have to worry about things like in-game framerates.
Lithvall got to work with Guerrilla on Horizon Zero Dawn, which means he's one of the main people to thank (among many others) for just how ridiculously good-looking Aloy's thick red locks are in that game, since his job was specifically to craft her hair (and work on everyone else's as well).
You can see more of Johan's work at his personal site.
