# Polygon

## Overview

The Polygon shape layer allows you to create your own custom polygon and assign a height to its inner and outer edges, allowing you to create flat areas, craters or mountains.

## Parameters

### Polygon Settings

* **Seed**\
  The Seed used in the layer.

* **Spline Smoothness**\
  Controls the number of steps for each spline, with a higher count producing a smoother and more rounded shape.

* **Surface Smoothness**\
  Rounds the curvature of the shape.

* **Corner Offset**\
  Rounds and shifts the shape outwards.

### Outside Settings

* **Height Offset**\
  Shifts the height of the polygon.

* **Outer Falloff**\
  Controls the outward falloff of the polygon.

* **Falloff Curve**\
  Adjusts the steepness of the outer falloff.

* **Noise Strength**\
  Adds noise into the outer falloff.

* **Noise Scale**\
  The scale of the added noise.

### Inside Settings

* **Height Offset**\
  Shifts the height of the inner influence area of the polygon.&#x20;

* **Inside Falloff**\
  Controls the inward falloff of the polygon.&#x20;

* **Falloff Curve**\
  Adjusts the steepness of the inner falloff.&#x20;

* **Noise Strength**\
  Adds noise into the inner falloff.&#x20;

* **Noise Scale**\
  The scale of the added noise.&#x20;

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/shape-layers/polygon.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.
