Map Range Node
This node converts (maps) an input value range into a destination range. By default, values outside the specified input range will be proportionally mapped as well. This node is similar to Map Value node but provides a more intuitive way to specify the desired output range.
Inputs
Value
The input value to be remapped.
From Min
The lower bound of the range to remap from.
From Max
The higher bound of the range to remap from.
To Min
The lower bound of the target range.
To Max
The higher bound of the target range.
Properties
Clamp
Clamps values to Min/Max of the destination range.
Outputs
Value
Standard value output.
Usage
One important use case is to easily map the original range of the Z-depth channel to a more usable range (i.e: 0.0 - 1.0) for use as a matte for colorization or filtering operations.
