Map Range Node

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

輸入

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.
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.

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].
