To Change the Sky Properties

To change the sky properties

1. Click Render tab System panel Autodesk Rendering .
2. Click the Environments tab, go to the Sky panel. If the controls are not active, you need to turn on the sun light first.
3. If you want to magnify the effect of the sky light, change the value in the Intensity Factor field.
4. Move the Haze slider to adjust amount of haze in the air. The range is from 0 (a completely clear day) to 15 (extremely overcast, or sandstorm in Sahara).
5. Move the Horizon Height slider to tune the position of the horizon. This affects not only the visual representation of the horizon (ground plane) but also the point where the sun 'sets'.
6. Move the Blur slider to adjust the amount of blurring between ground plane and sky.
7. Click the Color picker in the Night Color field, and set the desired value. This is the minimum color of the sky - the sky will never become darker than this value.
8. Click the Color picker in the Ground Color field, and set the desired value. This will be the color of the virtual ground plane.
