Depth of Field

The Depth of Field effect simulates the behavior of a real-life camera lens focusing on an object. This effect blurs image areas that are out of focus and generates Bokeh shapes. It really helps with creating realistic looking scenes and is one of the most important parts of a game's cut-scenes.

Properties

Property	Description
Enabled	If checked, the depth of field effect will be visible.
Blur Strength	The blur intensity in the out-of-focus areas. Allows reducing the blur amount by scaling down the Gaussian Blur radius. Normalized to a range of 0-1.
Focal Distance	Distance from the camera (in world units) to the center point of the focus area.
Focal Region	Controls the length of the focal region (in world units).
Near Transition Range	Near camera blur transition distance (in world units).
Far Transition Range	Far camera blur transition distance (in world units).
Depth Limit	The maximum pixel depth to be affected by the depth of field (in world units). Useful for stopping the effect on sky and skyboxes.
Bokeh Enable	If checked, bokeh shapes will be rendered.
Bokeh Size	Controls the size of the bokeh shapes.
Bokeh Shape	Defines the type of the bokeh shapes. Possible options: Option Description Hexagon The hexagon shape. Octagon The octagon shape. Circle The circle shape. Cross The cross shape. Custom A custom texture shape (uses the Bokeh Shape Custom Texture property).
Bokeh Shape Custom Texture	If Bokeh Shape is set to Custom, then this texture will be used for the bokeh shapes. For best performance, use small, compressed, grayscale textures (for instance 32px).
Bokeh Brightness Threshold	The minimum pixel brightness to create the bokeh. Pixels with lower brightness will be skipped.
Bokeh Blur Threshold	Controls Bokeh shape blur threshold value.
Bokeh Falloff	Controls bokeh shape brightness falloff. Higher values reduce bokeh visibility.
Bokeh Depth Cutoff	Controls bokeh shape generation for depth discontinuities.
