The settings on the right side of the dialog let you determine how much blurring is applied to the scene. Scene Blur Applies the blurring effect to the entire scene, not just a portion of it. Radial Blur Applies the blurring effect to the entire scene in a radial fashion, starting at the center of the frame. This is useful for emphasizing fish-eye lens effects and effects where the edges of the frame are blurred. This type of Focus depends on the Focal Range and Limit settings. A scene with a radial blur is applied. Focal Node Lets you select a specific object in the scene as the focal point for blurring. The selected objects remains in focus, while objects outside of the set Focal Limit are blurred. Select Displays the Select Focal Object dialog so you can select a single 3ds Max object to use as the focal object. The object you select can be animated over time, which results in animated follow focus effects. You can also choose your camera target as the focal object so its depth in the scene determines the focus. Affect Alpha When this option is selected, the blur effect is also applied to the Alpha channel of the image when you render to a 32-bit format. Select this option to composite the blurred image over another. Horiz. Focal Loss Specifies the amount of blur applied to the image in the horizontal (X-axis) direction. Values range from 0 to 100% focal loss. This parameter can be animated on page 6848. Lock Locks the horizontal and vertical loss settings together. When selected, the vertical focal loss is automatically updated to match your changes to the horizontal loss. 6874 | Chapter 22 Video Post
