Hellblade: Senua's Sacrifice
Developer Ninja Theory contracted a company called 3Lateral to scan the face of its model for Hellblade's protagonist, Senua, and it explains, but does not show the process in a new video.
The company 3Lateral doesn't want to share their secrets, so you won't see the technology, but it is apparently so big, that 3Lateral had to rent an apartment near its studios and use that to build the technology. Melina Juergens, whose face was scanned to represent Senua, explains that getting into the mystery contraption felt like getting into a spaceship, and she had to sign onto Skype while inside in order to communicate with everybody.
As mentioned previously, we don't get to see 3Lateral's mystery face-scanning spaceship machine, but we do get to see the results, and they do impress.
