vignettingIntensity
The magnitude of vignette (darkening around edges) effect to apply to the rendered scene.
Declaration
var vignettingIntensity: CGFloat { get set }Discussion
A vignette effect darkens the edges and corners of the rendered scene, simulating the effect of lens and barrel shape on the image produced by a physical camera. Higher values result in more darkening, and lower values result in a subtler effect. The default value of 0.0 results in no vignetting effect.
This property controls the level of darkening applied; the vignettingPower property controls the area of the rendered image to be darkened.
To enable this behavior, you must first enable the wantsHDR setting.
