Configure Depth of Field settings to create motion blur

You can set the camera depth of field settings for the camera interest for the chosen camera. The camera depth of field is the amount of space within lens view that maintains focus at given settings, such as camera speed, film speed, lens aperture, and so on. In MotionBuilder, it refers to a method of blurring the view depending on either the camera’s focal point or a specific distance from the camera.

Access the depth of field settings in the Render Options tab of the Cameras Navigator.

  1. In the Navigator, double-click a camera from the Cameras list.
  2. Click the Render Options tab.
  3. Turn on Use Depth of Field.

    Click the Keyframe (K) button to set keyframes on this property. You can modify the Keyframe attribute in the FCurve Editor as well.

  4. Select a Focus distance source from the following:
    • Camera Interest
    • Specific Distance

      Use the Specific Distance slider control to set the distance.

    • Focus Model

      Use the browse field beside Focus Model to locate and select a scene element from the scene browser.

  5. Adjust the Focus Angle to set the focal point for the depth of field.
