On June 8, software engineer Marco Alamia at Blizzard Entertainment shared a lengthy post describing a new piece of technology that was created in-house and implemented in Overwatch 2.
The new engine called Environment States is aiding developers to create and design appealing maps. Lighting artist Fabien Christin was the one who came up with the idea. He explained the purpose of Environment States in the post.
In short, Environment States are a way to bring changing atmospheres that complement the map. “Imagine traveling to Numbani and seeing the futuristic city illuminated in a warm African sunset,” he explained. The example he gave was describing the Sun and Sky aspect. It sets a particular mood based on the color and position of the sun.
