Primary Strength
This control determines the brightness of the primary hot spot.
Hot Spot Size
This control determines the diameter of the primary hot spot. A value of 1.0 represents a circle
the full width of the image.
Aspect
This controls the aspect of the spot. A value of 1.0 produces a perfectly circular hot spot. Values
above 1.0 elongate the circle horizontally, and values below 1.0 elongate the circle vertically.
Aspect Angle
This control can be used to rotate the primary hot spot.
Secondary Strength
This control determines the strength, which is to say the brightness, of the secondary hot spot.
The secondary hot spot is a reflection of the primary hot spot. It is always positioned on the
opposite side of the image from the primary hot spot.
Secondary Size
This determines the size of the secondary hot spot.
Apply Mode
This control determines how the hot spot affects the underlying image.
Add (Burn): This causes the spots created to brighten the image.
Subtract (Dodge): This causes the spots created to dim the image.
Multiply (Spotlight): This causes the spots created to isolate a portion of the image
with light and to darken the remainder of the image.
Occlude
This menu is used to select which channel of the image connected to the Hot Spot node’s
Occlusion input is used to provide the occlusion matte. Occlusion can be controlled from Alpha
or R, G, or B channels of any image connected to the Occlusion input on the node’s tile.
Lens Aberration
Aberration changes the shape and behavior of the primary and secondary hot spots.
In and Out Modes: Elongates the shape of the hot spot into a flare. The hot spot
stretches toward the center when set to In mode and stretches toward the corners
when set to Out mode.
Flare In and Flare Out Modes: This option is a lens distortion effect that is controlled by
the movement of the lens effect. Flare In causes the effect to become more severe, the
closer the hot spot gets to the center. Flare Out causes the effect to increase as the hot
spot gets closer to the edges of the image.
Lens: This mode emulates a round, ringed lens effect.
