alRemapColor by Anders Langlands, Jens Kafitz









The alRemapColor Node is a powerful Color Correction Node, giving same results as alRemapColor Node for Arnold (part of alShaders by Anders Langlands).


Please note other than alRemapColor Node inside alShaders this Mari implementation has additional Clamping functionality.


Node Overview


Node Ports


Supplies the map you want to adjust


A Value for Gamma Correction. 1.0 is no change to the Input.

If this port is mapped the corresponding value in the Node Properties will no longer be evaluated


A value for Saturation. 1.0 is no change to the Input.

If this port is mapped the corresponding value in the Node Properties will no longer be evaluated


An offset value for the Hue., ranging from -180 to +180. 0 means no change

If this port is mapped the corresponding value in the Node Properties will no longer be evaluated


A value to adjust the Contrast.

If this port is mapped the corresponding value in the Node Properties will no longer be evaluated


Adds gain to the signal, in effect a different form of contrast. Values less than 0.5 increase the gain, values greater than 0.5 decrease it.

If this port is mapped the corresponding value in the Node Properties will no longer be evaluated


A value to adjust the Exposure.

If this port is mapped the corresponding value in the Node Properties will no longer be evaluated


Please note other than the Extension Pack Exposure Adjustment Node in alRemapColor a Exposure

Value of 0 is equal to no change in order to be compatible with alShaders



Node Properties

Color


A Value for Gamma Correction. 1.0 is no change to the Input.


An  value for Saturation. 1.0 is no change to the Input.


An offset value for the Hue., ranging from -180 to +180. 0 means no change


Contrast


A value to adjust the Contrast.


The Pivot Point for Contrasting. Larger values than the pivot wil get 'crunched' towards white, lower values towards black

Value


A gain value on the input texture


A value to adjust the Exposure.


Please note other than the Extension Pack Exposure Adjustment Node in alRemapColor a Exposure

Value of 0 is equal to no change in order to be compatible with alShaders



Clamp


When checked, the Output of the Node will be clamped to Min and Max


The Minimum Clamp Value



The Maximum Clamp Value
