## Install

Requires the base plugin com.ivanmurzak.unity.mcp. After installing, reopen the editor so the new tool family appears in the agent's list.

```bash
openupm add com.ivanmurzak.unity.mcp.terrain
```

## When to ask the AI for it

Ask for landscape and open-world ground — hills, painted texture layers, scattered foliage.

Not sure if it's installed? Ask the agent "Do you have Terrain tools available?" — the terrain- tools only exist when the package is present.

## Example prompts

1. Create a 500×500 terrain and raise a gentle hill in the centre.
2. Add a grass and a rock terrain layer, then paint rock onto the steep slopes.
