Description

Generates a spherically projected rectangular shape. The shape transformation is driven by a transformation gizmo.

Background Image Input Color Input

Optional background onto which to compose the generated light.

Shape Image Input Color Input

Optional image to map onto Sphere light. Only used when Shape Color Mode is set to Image Input.

Shape Matrix

Matrix (Transformation Matrix)

Transformation control for the result. Result can be modified by directly interacting with the canvas.

Offset -2.0 - 2.0

Moves or translates the result. Result can be modified by directly interacting with the canvas.

Shape Rectangle, Disc

Choose what shape to place.

Shape Color Mode RGB, Temperature (Kelvin), Image Input

Choose what method to use to set shape color. Image Input enables use of the second input slot.

Color (Color value)

Only with Shape Color Mode set to RGB. Picks color for shape.

Shape Temperature 800.0 - 20000.0

Only with Shape Color Mode set to Temperature. Sets Kelvin value for shape color.

Shape Image Input Gamma sRGB, Linear

Only with Shape Color Mode set to Image Input. Determine how to interpret Shape Image Input.

Shape Exposure (EV) 0.0 - 10.0

Set exposure value for generated shape, Ideally matched to background image exposure value.

Shape Hardness 0.0 - 1.0

Set hardness of shape edges.

Hotspot Exposure (EV) 0.0 - 10.0

Set Exposure of central hotspot. Note this is not very visible in RGB mode.

Hotspot Size 0.0 - 1.0

Size of the central Hotspot.

Hotspot Falloff 0.0 - 1.0

Falloff of central hotspot.

Hotspot Position 0.0 - 1.0

X and Y position of the central hotspot.

Enable Backgound Input False/True

Toggles use of optional background image. Composites generated light on top of background.

Background Color (Color value)

If Background Input is not used, set a solid color background value here.

Background Gamma sRGB, Linear

If Background Input is used, set how to interpret Background input.
