Lighting & Shadows


When it comes to creating believable environments, the way the geometry within the level is lit plays an extremely important role. The human eye and brain expect light to interact with surfaces, fill a room, or cast shadows in a particular way. Anything that deviates from this can break up the immersive experience for the user.

Unreal Engine 3's lighting system is very flexible, allowing for different types of lights and shadows to all be used in harmony to create just the right look for any game. The Lightmass static global illumination lighting system makes setting up entire environments extremely easy as most of the leg-work is done by the lighting build process and dominant lights provide for detailed shadows without sacrificing performance.
