Spot Fill

The Spot Fill tool works like the standard fill light control, but adds circular area control for finer control of the effect with on-screen adjustments for size and position. |  | Fill: Extent to which the Light Color is added to the scene. Radius: Size of the area outside which the blur operation is at full strength. Spread: Threshold/softening region feathers the radius. Falloff: Sets the median point between the Radius and Spread. Light Color: Color used to illuminate shadow areas.
