# Sand

## Overview

The Sand Simulation adds granular sediment to the terrain. The Simulation moves the material from an unstable position downhill until a stable angle is reached and in the process fills up crevices and cracks.

## Parameters

<table><thead><tr><th width="179.6998291015625">Properties</th><th>Description</th></tr></thead><tbody><tr><td><strong>Slope Angle</strong></td><td>The angle at which sediment will no longer continue moving. The talus formed at the bottom of a mountain will take on this angle.</td></tr><tr><td><strong>Erosion Angle</strong></td><td>The angle at which sediment will become unstable and start slipping downhill.</td></tr><tr><td><strong>Spawn Level</strong></td><td>In which level the sediment gets added to the terrain. </td></tr><tr><td><strong>Spawn Amount</strong></td><td>The amount of sediment added to the 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/simulation-layers/sand.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.
