This page provides default information on the Sun Light Details rollout in Chaos Vantage. Overview Vantage Default Sun settings are divided into two tabs: basic and advanced.  – Basic settings tab.  – Advanced settings tab. An * next to a parameter name indicates that the parameter value has been modified. Basic settings Enabled  – Turns sunlight on and off. Color  – Changes the color of the sun. Intensity  – Specifies the intensity of the sun and can be used to reduce the default brightness.  Sun size mult  – Controls the visible size of the sun disc. This value can be used to control the softness of shadows cast by objects. Lower values produce sharper shadows, while higher values produce softer shadows.  Color mode  – Affects the way the color in the  Color  parameter affects the color of the sun. Filter  – Shifts the hue of the sun towards the color specified in the Color parameter. Direct  – Sets the color of the sun to match the color in the Color parameter. In this case, the intensity of the light does not depend on the Sun’s position in the sky and is controlled through the  Intensity  parameter. Override  – Sets the color of the sun to match the color in the Color parameter, but the intensity of the light still depends on the sun's position in the sky. Sun position mode  – Specifies the control mode for the sun's position in the sky. Manual  – Specifies a manual control of the sun position using the  Rotate ( ) transform tool. Altitude/Azimuth  – Specifies the use of  Altitude  and  Azimuth  values to control the sun's position. Geolocation  – Specifies the use of location coordinates, date, and time of day to control the sun position. Animated Geolocation  – Specifies the use of location coordinates, date, and time of day to control the sun position that can be animated in the Sun track in the animation editor. Altitude  – Sets the altitude position (in degrees) of the sun in the sky. Available for  Altitude/Azimuth  Sun position mode. Azimuth  – Sets the azimuth position (in degrees) of the sun in the sky. Available for  Altitude/Azimuth  Sun position mode. Set start keyframe  – Sets the current  Day / Month / Year  and  Hours / Minutes  values at the start of the sun animation track. Available for the  Animated Geolocation  Sun position mode. Set end keyframe  – Sets the current  Day / Month / Year  and  Hours / Minutes  values at the end of the sun animation track. Available for the  Animated Geolocation  Sun position mode. North offset  – Sets the altitude position (in degrees) of the sun in the sky. Available for  Geolocation  and  Animated Geolocation  Sun position modes. Latitude  – Defines the latitude position of the scene over the Earth’s globe. Available for  Geolocation  and  Animated Geolocation  Sun position modes. Longitude  – Defines the longitude position of the scene over the Earth globe. Available for  Geolocation  and  Animated Geolocation  Sun position modes. Day / Month / Year  – Specifies the day/month/year for which to compute the sun position. Available for  Geolocation  and  Animated Geolocation  Sun position modes. Hours / Minutes  – Specifies the hours/minutes for which to compute the sun position. Available for  Geolocation  and  Animated Geolocation  Sun position modes. Time zone  – Specifies the current time zone of the scene. The Time zone is not set automatically based on  latitude and longitude  values. Available for  Geolocation  and  Animated Geolocation  Sun position modes. Daylight saving time  – When enabled, it compensates for Daylight Saving Time(DST). Available for  Geolocation  and  Animated Geolocation  Sun position modes. Invisible  – When enabled, makes the sun invisible, both to the camera and to reflections. This is useful for preventing bright speckles on glossy surfaces where a ray with a low probability hits the extremely bright sun disk. Advanced settings Shadows  – When enabled (the default), the light casts shadows. Turn this option off to disable shadow casting for the light. The value moves the shadow toward or away from the shadow-casting object(s). Higher values move the shadow toward the object(s), while lower values move it away from the object(s). If this value is too extreme, shadows can "leak" through places they shouldn't or "detach" from an object. Other effects from extreme values include Moire patterns, out-of-place dark areas on surfaces, and shadows not appearing at all in the rendering. Affect diffuse  – Determines whether the light affects the diffuse portion of the materials. The value controls the light's contribution to the diffuse portion of the materials. Affect specular  – Determines whether the light affects the specular portion of the materials. The value controls the light's contribution to specular reflections.
