Remap Value is a utility node that allows you to take an input scalar value and remap its value using a gradient. One can remap this to a new output scalar value and/or color.

The input value is used to select a point along the gradient to use for the output value. The value specified by the Min attribute determines the input value that indexes the far left of the ramp while the Max attribute determines the value at far right.

The outColor is determined by the color gradient and the outValue by the value gradient. If one only uses the outValue, for example, then the color gradient is ignored.

Long name (short name)TypeDefaultFlags
color (cl) compoundn/aarrayoutputinputconnectablestorablekeyable
Color defines a range of color values used to remap the input value to the outColor. The Input Value parameter, along with the min and max attributes determine where to index into this ramp.

Position of ramp value on normalized 0-1 scale
color_Color (clc) float3outputinputconnectablestorablekeyable

Ramp Interpolation controls the way the intermediate values are calculated. The values are:
    None: No interpolation is done; the different colors just show up as different bands in the final texture.

    Linear: The values are interpolated linearly in RGB color space.

    Smooth: The values are interpolated along a bell curve, so that each color on the ramp dominates the region around it, then blends quickly to the next color.

    Spline: The values are interpolated with a spline curve, taking neighboring indices into account for greater smoothness.

inputMax (imx) float1outputinputconnectablestorablekeyable
This determines the input value which maps to the right of the gradients.
inputMin (imn) float0outputinputconnectablestorablekeyable
This determines the input value which maps to the left of the gradients.

InputValue is the raw input connection to remap.
outColor (oc) float30.0, 0.0, 0.0outputconnectable
OutColor is the final remapped color.

outValue (ov) float0.0outputconnectable
OutValue is the final remapped value.
outputMax (omx) float1outputinputconnectablestorablekeyable
This determines the output value at the graph top or white value.
outputMin (omn) float0outputinputconnectablestorablekeyable
This determines the output value which maps to the bottom of the graph or the color black.
value (vl) compoundn/aarrayoutputinputconnectablestorablekeyable
