Remap
The Calibrator. Scales and offsets values from one source range to a new destination range. This is essential for normalizing noise or creating specific value distributions for biomes.
Ports
| Port | Type | Direction | Description |
|---|---|---|---|
| Input |  Float | Input | The source float map. |
| Output | Float | Output | The remapped map. |
Logic
The Remap node performs a linear interpolation based on four parameters:
- Input Min/Max: The expected range of your source data (e.g., 0.0 to 1.0).
- Output Min/Max: The desired range for the result (e.g., 0.5 to 0.8).
Formula: Output = OutputMin + (Input - InputMin) * (OutputMax - OutputMin) / (InputMax - InputMin)
Parameters
- Input Min: Values at or below this point in the source will map to Output Min.
- Input Max: Values at or above this point in the source will map to Output Max.
- Output Min: The new minimum value.
- Output Max: The new maximum value.
Potential Use Cases
- Noise Normalization: If a Perlin Noise node is outputting values between 0.3 and 0.7, use Remap to stretch them back to the full 0.0 to 1.0 range.
- Inversion with Scaling: Set Output Min to 1.0 and Output Max to 0.5 to both invert and compress the range of an input.
