Parameters

Basic parameters

• Shape Color Mode:
  Select which method to use to determine the light's color. Available parameters will change based on this selection.
  • Temperature (Kelvin)
    • Temperature: 1000 - 27000
      Adjust the temperature of the light.
  • RGB
    • Color: color select
      Select the color of the light.
  • Image Input
    • Shape Image Input: image/brush
      Import an image to use as the color. You can use the brush tool to paint directly in the 2D view, but this can have unpredictable results with this filter.
  • Sample Background
    
    • Sample background doesn't make new parameters available - instead it bases the light color on background values.
• Exposure (EV): 0-10
  Adjust the exposure or brightness of the light.
• Sphere Radius: 0-1
  Adjust the size of the light.
• Position Mode:
  Change the method used to determine the lights position. Parameters in the Position Coordinates section will change based on selection.

Position Coordinates

Available parameters depend on the selection made for Basic parameters > Position Mode. If Distance from Origin is selected, the following parameters are available:

• Distance from Origin: 0-20
  Adjust the distance of the light from the camera.
• Camera Position: 0-1
  Adjust the relative position of the camera to the light in the X, Y, and Z axes.

If World Position is selected, the following parameters are available:

• Up Vector:
  Change which direction is up.
• Sphere World Position: -2 to 2
  Adjust the position of the sphere light in the X, Y, and Z axes.
• Distance from Origin: 0-20
  Adjust the distance of the light from the camera.
• Camera Position: 0-1
  Adjust the relative position of the camera to the light in the X, Y, and Z axes.

Shape

• Sphere Hardness: 0-1
  Soften or harden the edges of the sphere light
• Shading:
  Change the gradient of the light's exposure based on different styles of real world light. With Shading Light selected, additional parameters appear:
  • Shading Light World Position: -1 to 1
    Modify the position of the shaded area on the light
  • Penumbra Transparency: 0-1
    Adjust the level of opacity of the shaded area of the light.

Background

• Background Gamma:
  Select the color system used to determine background Gamma.
