Normalise
The Auto-Ranger. Scans the entire input field to find the minimum and maximum values, then scales all values so that they fall exactly within the 0.0 to 1.0 range.
Ports
| Port | Type | Description |
|---|---|---|
| Input |  Float | The field to normalise. |
| Output | Float | The field scaled to 0-1. |
Details
This node is extremely useful for "re-centring" data that has been modified by multiple math operations. If you add three noise fields together, your values might range from 0.0 to 3.0; Normalise will bring them back to the standard 0-1 range used by other nodes like Threshold or Biome Selector.
Potential Use Cases
- Distance Field Cleanup: After generating a Distance Field, use Normalise to ensure the "farthest" point is exactly 1.0, making it easier to use in subsequent logic.
- Combined Noise: If you've blended multiple noise fields with different intensities, use Normalise at the end of the chain to ensure the final result uses the full 0-1 range.
- Dynamic Terrain: When generating heightmaps, use Normalise to ensure your "highest peak" always reaches the top of the allowed vertical range, regardless of the noise settings.
