Set Range
Set Range by Jens Kafitz |
NodeGraph / Right Mouse Click / Nodes / Filter / Extension Pack / Color Correction / The setRange Adjustment is a value remapping tool similar to Maya's setRange Hypershade Node.
It is in behavior similar to a Levels Adjustment and is useful for example to set correct displacement heights etc.
MAIN TAB
The value that is defined as Minimum Value on the Input Color. For example on a gradient black to white, when increasing the OldMin
any incoming Value below OldMin will become black.
The value that is defined as Maximum Value on the Input Color. For example on a gradient black to white, when decreasing OldMax
any incoming Value above OldMax will become white.
The value that is defined as Minimum Value on the resulting Output. For example on a gradient black to white, when increasing NewMin
the previously black areas will be the value set in NewMin.
The value that is defined as Maximum Value on the resulting Output. For example on a gradient black to white, when decreasing NewMax
the previously white areas will be the value set in NewMax.
MultiplyScale multiplies against the sliders of OldMin,OldMax,NewMin & NewMax.
By setting values over 1.0 you can create or adjust floating point output (16bit,32bit channels).
When ticked on the the result of the OldMin and OldMax will be clamped first before getting passed
to the NewMin and NewMax settings.
This will more reliably keep values exactly within the range of NewMin and NewMax for example
when the OldMax was lowered below 1.0 etc.
When ticked on the Output of the Node will always be clamped to 0 - 1 regardless if the NewMin is lower than 0,
or the NewMax is higher than 1.
If you are using 16bit float or 32bit values you should untick the OutputClamp
CHANNELS TAB
Determines which channels are affected by the remapping operation. Default is RGB with Alpha being unaffected.
