# Path

## Overview

Path layers modify terrain based on custom paths set up in World Creator. This feature enables the building of various structures like mountains, valleys, rivers, or streets.

## Parameters

### Path Settings

* **Width**\
  The base width is multiplied by the width of each control point. If the overall width is 0, individual point widths cannot exceed 0.

* **Falloff**\
  Falloff of the path. This is added to the path width.

* **Falloff Curve**\
  Falloff steepness.

* **Noise Strength**\
  The noise is added to the path width.

* **Noise Scale**\
  Adjusts the noise scale along the path's length.

* **Closed**\
  Connects the first and last control point if enabled.

* **Height Offset**\
  Shifts the whole path upwards or downwards.

* **Flatten**\
  Flattens the heights of all control points.

### Procedural Width

The Procedural Width parameters allows you to automatically set the node widths between the set width range.

* **Range**\
  The range between which the node widths will be set.

* **Mode**\
  Allows you to select from a bunch of different types like ascending, descending, zigzag or random distribution.

### Spline Export

* Export Spline\
  Allows you to export the spline for usage in a render engine.
