6.18.5. Distance-Based Fog

When working in 3D, the layers on your timeline exist in a 3D space. Fog can be added to the scene, to fill the space between the layers.

With fog turned off, all layers are rendered the same regardless of their distance from the camera. A layer in the far distance will be just as bright as a close-up layer. If you turn fog on, layers will gradually fade to the fog color over a given distance, simulating atmospheric haze.

The Fog properties can be adjusted for each composite shot timeline, and are accessed in the Properties for each timeline

Fog Properties

The fog properties can be accessed from the Media panel or the Timeline.

Media Panel

1. Click the cog icon to the right of any composite shot’s name, to open the properties for that timeline.
2. Click the Advanced tab to access the fog properties.

Timeline

1. Click the cog icon at the lower left corner of the timeline to open the properties for the current timeline.
2. Click the Advanced tab to access the fog properties.

• Enable: Turns the fog on and off.
• Near Distance: The distance at which layers begin to fade into the fog.
• Far Distance: The distance at which layers will be completely fogged.
• Density: When using exponential fall offs, this increases the rate at which the fog thickens.
• Fall Off: Change between a linear fall off and various exponential fall offs. Exponential fall offs are more natural but can be more difficult to predict.
• Color: Change the color and brightness of the fog.
