Depth Cue is a set of plug-ins that adds realistic depth effects to 3D layers. Each effect works on a 3D layer and changes based on the location of the layer, lights, and cameras in 3D space.

Included with Buena Depth Cue are 5 plug-in effects including:

• 3D Composite:
  Allows 2D footage with a depth channel, such as you might generate in Maya, 3D Studio Max, or other 3D applications, to interact with After Effects' 3D layers.
  
• Depth:
  Displays the depth of each layer in grayscale for use as a gradient map with other plugins, or with other applications.
  
• Falloff Lighting:
  Lights your layers realistically. Layers farther away from lights are illuminated less than those near lights.
  
• Fog:
  Shrouds your layers in a light haze or a deep, murky mist. Objects farther away from the camera have more fog applied to them than objects close to the camera.
  
• Rack Focus:
  Produces realistic depth of field effects and focus pulls, including simulating boke and anamorphic lens effects.
  
• Camera Mapper:
  Turn 2D stills and footage into 3D scenes right in After Effects. It works by projecting parts of your 2D footage onto 3D solids in a composition, then rendering the composition from different angles.
  
• Flipside:
  Maps one layer onto the back side of another layer. This allows you to flip the front layer over to reveal the back layer. It does this without creating any gap between the 2 layers, and without the occlusion problems that sometimes show up when trying to put 2 layers very close together in a composition
