The Sky Atmosphere gives an approximation of light scattering through a planetary atmosphere's participating media, giving outdoor levels a more realistic or exotic look by including the following: The Time-of-Day Preview displays different times of day based on the settings that are applied to the Sky Atmosphere component. The Hemisphere View shows a visual representation of your atmosphere, taking into account Rayleigh and Mie scattering along with Absorption.

You can have two atmospheric Directional Lights that receive sun disk representation in the atmosphere with sky color that depends on the sunlight and atmosphere properties. Set a high value for the Dynamic Shadow Distance. For instance, the examples below used a shadow distance of 100000000 units (or 1000 kilometers).If using multiple Directional Lights, set the Atmosphere Sun Light Index for each; for instance, 0 for the Sun and 1 for the Moon.

Enable Cast Shadow on Atmosphere to cast shadows from opaque objects. Also, enable Cast Cloud Shadows to enable shadow casting from cloud materials when using the Volumetric Cloud system. Achieving cinematic quality of atmosphere rendering is done by disabling the Sky View and Aerial Perspective LUTs optimizations, which use a lower resolution to be performant. They can be disabled by setting r.SkyAtmosphere.FastSkyLUT and r.SkyAtmosphere.AerialPerspectiveLUT.FastApplyOnOpaque to 0. Atmosphere will become slower to render but produces fewer visual artefacts with high-frequency detail that appear in some areas, such as a planet's shadow or its scattering lobe. You'll also want to increase the tracing quality on the Sky Atmosphere component (see above). Shadowing from a Directional Light source is used to create sunlight shafts within the atmosphere for ground-level and space views.When the sun is at its zenith, it should be set to 120000 lux (or cd:sr*m

Enable the Sky Atmosphere component by following these steps using the Modes panel in the Level Editor: The Sky Atmosphere system is optimized for scenes that are on ground level. However, there is nothing preventing you from traveling from the ground to a high aerial view, or even outer space. While the transition through the atmosphere should be seamless—without a noticeable transition—from the look-up tables (LUTs) to per pixel tracing, you may sometimes experience a hitch or when this happens. Aerial perspective that simulates the curvature of the world when transitioning from ground to sky to space views. In this material, you will have the freedom to compose the sky, sun disk, clouds and aerial perspective. Also, you will have to compute lighting on the clouds and other elements in the sky. Several Material Expressions can be used to achieve this in your materials. You can find them by searching the term "SkyAtmosphere" in the Material Editor. The Graph View shows a representation of Rayleigh, Mie, and Absorption values within the Sky Atmosphere component's set Ground Level and Atmosphere Height.

For outer space views, enable Per Pixel Atmosphere Transmittance to apply accurate planetary shadowing that also casts shadows on nearby celestial objects, such as a moon. Set up logic to adjust and tweak atmospheric properties when in outer space to have less particles near the ground, making them more uniform and height distributed. Trade performance for quality increase by increasing the number of samples with r.SkyAtmosphere.SampleCountMax or r.SkyAtmosphere.DistanceToCountMax.
