Depth of field

IntermediateArtist

By default, rendering produces a very sharp image, which can look artificial. Depth of field effects simulate the behavior of a real camera lens focusing an object, leaving background and foreground objects out of focus.

To create the effect, Xenko creates several versions of the original image with different intensities of blur, and interpolates between them. The more layers used, the better the quality, but at performance cost.

Properties

Property	Description
Size	Size of the bokeh (Wikipedia), expressed as a factor of the image width so it's resolution-independent. The bigger the size, the worse the performance
DOF Areas	Areas of the depth of field. There are three main zones defined by their distance from the camera: near out-of-focus area (from X to Y), in-focus area (from Y to Z), and far out-of-focus area (from Z to W)
Technique	The technique affects both the performance and the shape of the bokeh.Circular Gaussian is fast but unrealistic.Hexagonal Triple Rhombi is heavier than Gaussian.Hexagonal McIntosh is the heaviest.
Auto Focus	Automatically updates the DOF areas so the camera focuses on the object at the center of the screen
