Intensity
...
This drives the overall intensity of the sky. It is a direct multiplier of the sky radiance function.
Intensity 1.0 | Intensity 1.5 | Intensity 2.0 |
...
Turbidity
...
This parameter determines the overall aerosol content of the air. As an example, a moist day will have higher turbidity values than a dry day. Values range between 1 and 10.
Turbidity 1.0 | Turbidity 4.0 | Turbidity 10.0 |
...
Ground Color
...
Changing ground color affects the brightness of the whole sky-dome, especially in high turbidity settings. High albedo values can occur in winter scenes - snow reflectance is very bright so almost all incident radiation is reflected and backscattered towards the viewer.
Ground Color is white | Ground Color is green | Ground Color is blue |
...
Elevation
...
This the elevation of the sun.
Elevation 5 | Elevation 20 | Elevation 40 |
...
Azimuth
...
This is the azimuth of the sun.
Azimuth 90 | Azimuth 180 | Azimuth 270 |

Sun Size
...
The size of the sun in the sky, in degrees. The default value (0.51 degrees) is the size of the sun as seen on earth. Note that changing the size of the sun doesn't affect the overall radiance of the sky in this model but the objects will receive more light, as seen in the images below.
Sun Size 0.51 | Sun Size 1.51 | Sun Size 3.51 |
