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.
  • 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.
