The Dunes filter adds sandy dunes to your terrain.

## **Parameters**

<table><thead><tr><th width="199.7999267578125">Property</th><th>Description</th></tr></thead><tbody><tr><td><strong>Scale</strong></td><td>Scales the x/y size of the dune pattern.</td></tr><tr><td><strong>Height</strong></td><td>Controls the height of the dunes.</td></tr><tr><td><strong>Height Offset</strong></td><td>Pushes the whole filter result up or down.</td></tr><tr><td><strong>Spawn Strength</strong></td><td>Controls the height of the base spawned dunes before they are modified by the wind.</td></tr><tr><td><strong>Octaves</strong></td><td>The number of dune noise octaves used by the filter. Higher Octaves results in higher detail and more dunes.</td></tr><tr><td><strong>Push</strong></td><td>Controls how far the crest of the dune is pushed ahead. Higher values create more pronounced, sharper shapes.</td></tr><tr><td><strong>Pinch</strong></td><td>Pinches the crest of the dunes.</td></tr><tr><td><strong>Linearity</strong></td><td>Applies random rotation to the individual dunes, creating a less parallel image.</td></tr><tr><td><strong>Direction</strong></td><td>Allows you to orient the dunes.</td></tr><tr><td><strong>Wind Length</strong></td><td>Controls how far the wind can push the dunes.</td></tr><tr><td><strong>Smoothing</strong></td><td>Smoothes the base terrain.</td></tr></tbody></table>

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.world-creator.com/reference/terrain/biome/filters/arid/dunes.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
