Inputs

• Color Field: (optional) Optional field that controls the color of the light.
  • Coordinate Types: vec3
  • Context Types: LightContext
  • Return Types: float vec4
• Attenuation Field: (optional) Field controls the color of the light based on the position of surface hits where it is being applied. The resulting color is multiplied by the `Color` parameter and `Intensity`.
  • Coordinate Types: float
  • Context Types: LightContext
  • Return Types: float vec4
  • Supports Variables From Inputs: colorField
• attenuationField: (optional) Field/function that controls the slope and coloration of the attenuation rolloff is shaped. It can be used to make the light shift from one color to another, or to control the sharpness of the rolloff.
