Setting Cloud Height

The height of your clouds has an impact on the appearance of your sky. Greater heights will result in smaller, more distant cloud formations, as well as a thicker band of haze at the horizon. Lower heights result in larger, more languorous cloud formations and a thinner band of haze at the horizon. The Cloud Height controls in the Sky & Fog palette let you interactively set the height of the cloud layer in the sky. For example, you can see how the clouds change in these skies as the cloud altitude value changes from 10% to 90%.

There are two things to remember when working with this control. First, the Cloud Height will affect the size of your Haze band, if you have a haze setting greater than zero. The higher the altitude, the wider the haze region will be on the horizon. Second, remember to lower your altitude setting if you are creating a nighttime scene. Since high altitudes increase the size of the horizon Haze region, the sky will be too unnaturally bright for realistic night scenes.

To set cloud height numerically:

1. If it's not already visible, display the Sky & Fog palette by clicking the text item on the menu bar.
   
   
2. Click the Sky Lab button. The Sky Lab dialog appears.
   
   
3. Click the Cloud Cover tab.
   
   
4. Drag the slider or enter a value in the Cloud Height field.
   
   

You can also set Cloud Height in the Sky & Fog Palette.
