Map Range Node

The Map Range node remaps a value from a range to a target range.

輸入

Value/Vector: The input value or vector 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.
Steps: The number of values allowed between To Min and To Max when using Stepped Linear interpolation. A higher value will give a smoother interpolation while lower values will progressively quantize the input.

Data Type

Map Range supports both Float and Vector data types. Changing the data type will also update the sockets to reflect the data type chosen.

Interpolation Type

The mathematical method used to transition between gaps in the numerical inputs.

Linear: Linear interpolation between From Min and From Max values.
Stepped Linear: Stepped linear interpolation between From Min and From Max values.
Smooth Step: Smooth Hermite edge interpolation between From Min and From Max values.
Smoother Step: Smoother Hermite edge interpolation between From Min and From Max values.

Clamp

If enabled, the output is clamped to the target range.

The Noise Texture node outputs a value in the range [0, 1]. We can use the Map Range node to remap this value into the range [-1, 1].
