 <a id="details" name="details"></a>## Detailed Description

Represents the builder for an Ambient Source with CIE Standard Overcast Sky type.

The Ambient Overcast Sky Source Builder is used to create and edit Ambient Overcast Sky Source features.

This sky model is based on the publication of the CIE: ISO 15469:2004/CIE S 011:2003: Spatial distribution of daylight - CIE standard general sky.
