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.
