Square Enix studio Luminous Productions has unveiled a new tech demo called “Back Stage” that shows how it uses ray-tracing tech. The demo is rendered in real-time.

Luminous Productions was established last year and staffed with former Final Fantasy XV staff. The game’s director Hajime Tabata initially headed up the studio. He has since left Square Enix.

As Siliconera points out, this tech demo shows off next-gen possibilities for its in-house Luminous Engine. Here, the real-time ray tracing shows the character’s face and emotions reflected in a realistic way that simply isn’t possible in previous real-time rending tech.
