Shape Light
Shape Light
In: 3D View/HDRI Tools
Complex
Description
Generates a spherically projected rectangular shape. The shape transformation is driven by a transformation gizmo.
Inputs
- 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.
Parameters
- 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.
- Matrix: (Transformation Matrix)
- 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.
