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 InputOptional background onto which to compose the generated light.
• Shape Image Input: Color InputOptional 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, LinearIf Background Input is used, set how to interpret Background input.
