Which Halo Studios art director cited Unreal's Lumen and Nanite technologies?

Chris Matthews cited Unreal’s Lumen and Nanite technologies when explaining Halo Studios’ move to Unreal Engine 5.

Matthews is the art director for Halo: Campaign Evolved, the ground-up remake of Halo: Combat Evolved. He described Unreal Engine 5’s lighting and rendering tools as opportunities to make the game’s environments more detailed and interactive while preserving the recognizable visual identity of the original Halo.

Lumen is Unreal Engine 5’s dynamic global-illumination and reflection system. Nanite is its virtualized geometry technology, designed to display extremely detailed models efficiently. They are often mentioned together, but they do different jobs: Lumen primarily affects lighting, while Nanite primarily affects geometry and scene detail.

A common mix-up is choosing Marcus Lehto, Paul Russel, or Shi Kai Wang. Those names are associated with other parts of Halo’s history, but the art director specifically connected with the Lumen-and-Nanite explanation is Chris Matthews.
