Enables special camera aperture settings. Without this option, the settings are taken from the active camera in the scene.
F-Num
Aperture number. Affects the depth of field, the aggressiveness of blurring out-of-focus objects.
Num Blades
For a polygonal aperture, specifies the number of blades. If the value is equal to the maximum, then the diaphragm is considered perfectly circular.
Blade Curvature
Curvature of blades, rounding. If the curvature is 1, then the diaphragm is considered perfectly circular. The rounding can be negative - in this case, the blades are rounded towards the center of the lens axis.
Rotation
Rotation of the diaphragm around the lens axis, in degrees.
Aperture Template
You can define the shape of the aperture using an arbitrary texture map.
Cat Eye
Enables the "cat's eye" effect. In real cameras, the lens always has a certain size. In this case, the elements of the lens structure can partially overlap the field of view, which results in blurring of bright objects in the form of figures resembling a cat's eye.
Diameter - sets the inner diameter of the lens in millimeters.
Distance - sets the distance from the matrix to the outer edge of the lens along the optical axis in millimeters.
Bias
Not a physical parameter that shifts the sampling density from the center of the iris to the edges or in the opposite direction.
