HD Emission Node

The HD Emission node calculates a emission HDR Color according to what is set over is inputs.
NOTE: This is a HDRP specific node.


Node Parameter Description Default Value
Intensity Unit Type of physical light units to control the strength of the emission.
  • Luminance
  • EV100
 Luminance
Normalize Color Normalizes the LDR input color before calculating the final HD Emission value ( pre-multiplies it by the reciprocal value of the calculated luminance ) False
Input Port Description Type
Color LDR color value for the emission Float3
Intensity Intensity of the final color Float
Exposition Weight Value between 0 and 1 to set how exposure affects emission ( 0 exposure does not effect emission and 1 fully affects emission ). Float
