Represents both the sun and sky for scenes with a dynamic time of day.
ScatterSky renders as a dome shaped mesh which is camera relative and always overhead. It is intended to be part of the background of your scene and renders before all other objects types.
ScatterSky is designed for outdoor scenes which need to transition fluidly between radically different times of day. It will respond to time changes originating from a TimeOfDay object or the elevation field can be directly adjusted.
During day, ScatterSky uses atmosphereic sunlight scattering aproximations to generate a sky gradient and sun corona. It also calculates the fog color, ambient color, and sun color, which are used for scene lighting. This is user controlled by fields within the ScatterSky group.
During night, ScatterSky supports can transition to a night sky cubemap and moon sprite. The user can control this and night time colors used for scene lighting with fields within the Night group.
A scene with a ScatterSky should not have any other sky or sun objects as it already fulfills both roles.
ScatterSky is intended to be used with CloudLayer and TimeOfDay as part of a scene with dynamic lighting. Having a ScatterSky without a changing time of day would unnecessarily give up artistic control compared and fillrate compared to a SkyBox + Sun setup.
