Redshift Sky

In conjunction with the Physical Sun light and Redshift Camera Exposure controls, Redshift supports a Physical Sky environment, with parameters similar to the Physical Sun light, because it is based on information provided in the paper 'A Practical Analytic Model for Daylight', by A.J. Preetham, Peter Shirley and Brian Smits, which successfully provides a model for an 'all weather' sky shader.

To directly obtain a meaningful unity of physically correct sun illumination, sun display and sky display, the combination RS Sun & Sky Rig can be called. Otherwise an already existing Redshift Physical Sun light object can be linked manually at the Redshift Sky object as sun.
