‘Assassin’s Creed Shadows’ Advances Lighting technology
Updated June 28, 2025
Behind the scenes of video game development lies a complex web of systems that bring virtual worlds to life. Lighting, a critical element, considerably impacts the visual experience, influencing how players perceive and interact with game environments. Simulating realistic light behavior involves intricate calculations of reflection, absorption, and diffusion.
Historically, dynamic lighting posed a significant computational challenge, often hindering game performance. Though,advancements in technology are enabling developers to create more vibrant and lifelike game worlds.
Ubisoft’s upcoming “Assassin’s Creed Shadows” showcases these advancements. Nicolas Lopez, technical architect at Ubisoft, discussed the game’s innovative lighting solutions at the Game Developers’ Conference this spring.
One striking example Lopez cited was the difference in lighting calculation time between “Assassin’s Creed Shadows” and “Assassin’s Creed Unity.” If “Shadows” had used the same methods as “Unity,” pre-calculating and rendering all the lighting would have taken nearly two years and required 2TB of storage. By comparison, “Assassin’s Creed Shadows” requires 115GB on PC for the entire game.
Lopez explained that older “Assassin’s Creed” titles, such as “unity” and “Syndicate,” featured smaller, denser cities, around four square kilometers. Developers used 50-centimeter uniform lighting probes to render global illumination.
Global illumination (GI) encompasses various techniques that mimic realistic lighting, including indirect lighting. These techniques involve cube maps, screen-space reflections, and probe lighting.
With “Assassin’s Creed Origins,” the game world expanded to 256 square kilometers, necessitating a shift to a dynamic system to manage the increased data. According to Lopez, probe density now varies based on scene complexity, with dense urban areas still using 50-centimeter spacing, while open landscapes use less.
The team adopted the Academy Color Encoding System (ACES), a global color standard used in the film industry. This ensures consistency across different devices and applications, so characters, buildings, and foliage appear cohesive.
Color Look-Up Tables (LUTs) further allow the team to adjust the visual tone and color grading to match weather and environmental conditions.
Lopez said the team reworked key parts of their physically based rendering and exposure pipelines to behave more accurately in low-light conditions. Ray tracing helps inform the way lighting works, allowing the team to deliver nights that feel moody and authentic, without relying on artificial fill lighting.
With ray tracing helping to inform the way lighting works in Shadows,the team can “deliver nights that feel moody and authentic,without relying on artificial fill lighting,” Lopez said.
Lopez said these changes create a unified, reactive visual experience where everything feels connected, pushing both Anvil and “Assassin’s Creed” forward.
What’s next
“Assassin’s Creed Shadows” exemplifies how video game design adapts to new technology, enabling designers to create dynamic worlds more efficiently without sacrificing fidelity. Gamers, in turn, experience more immersive and realistic environments.
