How Light Comes Alive in Dying Light on PS4

         

Hello, I’m Maciej Jamrozik, the Lead Technical Artist at Techland, developer of the upcoming first-particular person, motion survival-horror recreation Dying Light.

Light and shadow play a crucial role in Dying Light. They affect not only the gameplay and its day-and-night cycle, but also the visuals.

This video illustrates how the game uses a physically-based lighting system, which means that light is generated in accordance to the actual laws of physics. This in turn assures that lighting looks convincing and cohesive, regardless of the conditions and surroundings. It’s especially important as Dying Light features a variety of locations and environments, from open spaces to claustrophobic rooms, as well as a range of weather conditions and changing time of day.

One of the most important parameters of indirect lighting is “roughness,” which defines the level of smoothness and dullness of a surface. Implementing our new physics model eliminated the limitation of using only preset groups of materials, which translates to much more varied and faithful representations of materials in the game. Our artists now have full freedom over the level of roughness on objects, and can save the result in a form of texture.

On PS4, we use the console’s additional horsepower to generate dynamic reflections. Similarly, they make use of the “roughness” to diffuse and reduce the impact of the specular reflection. It helps render the given material in the most realistic way possible.

Dying Light boasts a dynamic weather system, together with a real-time passage of time. That’s why indirect lighting data, which is stored in so called environment light probes, has to change according to the current weather and the time of day. These two factors can change independently. That’s why we compute the Spherical Harmonix function offline for all weather conditions and times of day, and then it is dynamically interpolated in the game.

The physically based lighting model influenced what all wet surfaces look like. When it’s raining, wet surfaces get increasingly shiny through the modification of the roughness parameter. We emphasize that weather conditions, like time of day, change gradually, and it applies also to all wet surfaces. As a result, a surface becomes wet only if it is actually exposed to rain.

Every other box straight away enhanced with the aid of the brand new physics edition is water. It’s a the most important characteristic, for the reason that Loss of life Mild lets in the participant to swim and dive. Water within the recreation can have various ranges of transparency, which impacts gentle diffusion. Furthermore, water has an impact on all objects immersed in it. We alter the parameter of roughness in order that they give the impression of being moist, however simplest to the purpose of immersion. The remainder above the water stage continues to be dry.

The entire above enhancements, and lots of different modifications, are to make it possible for Death Mild will ship an unheard of visible constancy with a purpose to shock you with its degree of realism. Subsequent year, while you’re leaping between roofs and looking to lose the zombie horde at the back of you, take a second to understand all of the nice lights results round you.
