Camera Depth of Field settings

Use the Depth of Field options tab to configure selected cameras for motion blur.

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.

Use Depth of Field option

When on, you can set the camera's depth of field, which 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.

The Depth of Field settings are a method of blurring the current camera view based on either the camera’s focal point or a specified distance from the camera.

This is a keyframeable property that can be later modified in editors such as the FCurve Editor.

Focus Distance Source

Camera interest: Bases the depth of field on the camera interest. Models at the camera interest are in focus. As you move toward or away from the camera interest, models become increasingly blurred.
Specific Distance: Bases the depth of field on a point defined by a specific distance from the camera interest.
Focus Model: Bases the depth of field on a selected scene element such as character. When selected, use the browse field beside Focus Model to locate and select a scene element from the scene browser.

Specific Distance

Use this to set a distance value when Specific Distance is selected as the Focus Distance.

This property can be keyframed and later modified in editors such as the FCurve Editor.

Focus Angle field

Use this to specify the angle of the focus or blur. Increasing the angle value decreases the depth of field, and increases the amount of blur. Decreasing the focus angle increases the depth of field, and decreases the amount of blur.

This property can be keyframed and later modified in editors such as the FCurve Editor.

Use Motion Blur option

When on, a motion blur effect is created for the selected camera.

Enable Real Time option

When on, you can view the Motion Blur effects in real time. When off, the blur effect is visible only when rendered.

For better results, leave Enable Real Time turned off as the render time motion blur calculation is more precise.

Intensity (In Frames) slider

Sets the duration, in frames, of the Motion blur effect. Use higher values to generate stronger blur effects and lower values subtle blurs.
