# Rocky

## **Overview**

The Rocky Erosion filter adds a simple but really powerful and versatile erosion to WCs range of filters.

## **Parameters**

<table><thead><tr><th width="199.7999267578125">Property</th><th>Description</th></tr></thead><tbody><tr><td><strong>Strength</strong></td><td>Controls the strength of the filter effect on the terrain.</td></tr><tr><td><strong>Sign</strong></td><td>Inverts a part of the computation, leading to a different result.</td></tr><tr><td><strong>Step Size</strong></td><td>The step size of the filter particles. Increase this to get more elongated features.</td></tr><tr><td><strong>Sample Size</strong></td><td>The sample size the algorithm uses to compute the terrain normal for particle flow computation.</td></tr><tr><td><strong>Depth</strong></td><td>Changes the overall depth feeling of the filter effect.</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/basic-erosion/rocky.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.
