Fog

Fog can add an element of sensuality, mystery, and even realism to your scenes. It acts like a thin layer of cloud close to the ground.

Using Fog you can create the illusion of depth without having to add distant objects. Fog can create a sense of depth in your scene.

In this scene, the fog was used to add depth to the road as it moves away from the camera. Notice how the feeling of depth was created without the addition of background objects.

You can set intensity, height, and color attributes for the fog. For example, you can see how the fog changes in these skies as the Fog value changes fro 10% (top) to 90% (bottom).

The fog acts as a global layer covering the entire scene. Its color and intensity are the same throughout the scene.

To set Fog attributes 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 Atmosphere tab.
4. Click the Fog Density and/or Thickness fields, then enter a value. These fields set the amount of fog rendered in your image. The range is 0 to 100% with a default value of 0%.
5. Click the Base Height field, then enter a value. This field sets the height of fog rendered in your scene, assuming there is a value greater than zero in the Fog field. The range is 0 to 100%, and the default value is 0%. It translates the entire atmospheric effect up or down without changing the density or thickness. Base Height provides control over density at low altitudes, such as in valleys. In earlier versions of Bryce, you had to move the entire scene up or down relative to the atmosphere.
