Helper node to generate a Blackbody ramp using the same logic as the Pyro Shader, which is slightly different than the Blackbody VOP.
Note
To be removed in Houdini 24.0.
Parameters ¶
Override Size
Ignore the file native’s size and use the specified one instead
Global Look Controls ¶
Pyro Shader Method
Selects between using the logic used by the Pyro Shader or the built in Blackbody VOP
tonemap
The blackbody algorithm’s output has a huge dynamic range.
Gamma
Additional gamma control to tonemap the output image
Temperature Controls ¶
temperature low
The temperature corresponding to an input value of 0.
temperature high
The temperature corresponding to an input value of 1. For example, if this parameter is 5000 (the default), then an input value of 1 means a temperature of 5000 degrees Kelvin.
Intensity Controls ¶
adaptation
Squashes or stretches the low end of the generated intensity, similar to exposing a photograph for shadows.
burn
Manipulates the high end of the generated intensity.
Ramp Intensity
Multiplier on the ramp values
Clip Value
Value of the image where the fade to black begins
