Set Range by Jens Kafitz









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.


Options



Main


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 a 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 a the value set in NewMax.


Extra Attributes


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).


Clamping is the process of clipping values below 0.0 and above 1.0.

When applying the setRange to a 32bit Displacement Map while clamping is turned on,

the resulting output will likely be clipped at 0.0 and 1.0.

On the other hand when turning clamping off and setting MultiplyScale Values above 1.0 you can

achieve values over 1.0 and below 0.0 even from a regular 8bit texture.


Channels


Determines which channels are affected by the remapping operation. Default is RGB with Alpha being unaffected.
