Setting Frequency & Amplitude

The Frequency and Amplitude control lets you set the types of cloud formation you'll see in your sky. By combining these two controls you can change your clouds from light and fluffy to dark and brooding. Use Frequency and Amplitude to control the types of cloud formations in your scene.

This graph shows the effects of different Frequency and Amplitude settings on a sky. Frequency values range from 2 at the top to 150 at the bottom. The Amplitude values range from 50 at the left to 500 on the right.

To set Frequency and Amplitude 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 Frequency field. The Frequency field controls the frequency (scale) of cloud formations in your scene.
   
   
5. Drag the slider or enter a value in the Amplitude field. The Amplitude field controls the amplitude (edge softness) of clouds in your scene.
   
   Drag right to increase the Amplitude amount, drag left to decrease the amount.
   
   

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