# Clean Restart (Pro)

## Clean Restart Unity

Automatically restart Unity with a clean cache to fix import issues and ensure clean configuration changes.

{% hint style="info" %}
**Professional Feature**: Clean Restart Unity is only available in realvirtual Professional.
{% endhint %}

**realvirtual → Settings → Clean Restart Unity (Pro)**

### What It Does

1. Saves your current work
2. Closes Unity completely
3. Deletes the Library folder (Unity's cache)
4. Restarts Unity automatically
5. Reimports all assets with clean cache

{% hint style="warning" %}
This process takes 5-15 minutes depending on project size.
{% endhint %}

### When to Use

* **After configuration changes** (switching between Professional/Starter/etc.)
* **Import errors or corrupted assets**
* **Shader compilation problems**
* **Unexpected Unity behavior**
* **Before important builds**

### How to Use

1. Click **realvirtual → Settings → Clean Restart Unity (Pro)**
2. Confirm the dialog
3. Wait for Unity to restart and reimport assets

The process is fully automated - just wait for completion.

### For Non-Professional Users

If you don't have realvirtual Professional, you can achieve the same result manually:

#### Manual Clean Restart Steps:

1. **Save your work** in Unity
2. **Close Unity completely**
3. **Delete the Library folder** in your project directory
   * Navigate to your project folder
   * Delete the entire `Library` folder
4. **Restart Unity** and open your project
5. **Wait for reimport** (5-15 minutes)

#### Important Notes:

* The `Library` folder is Unity's cache - deleting it is safe
* Your project files (`Assets`, `ProjectSettings`) are never touched
* Unity will recreate the Library folder automatically

### Troubleshooting

**Unity won't close?** Wait 2 minutes, then use Task Manager (Windows) or Activity Monitor (Mac) to force-close Unity processes.

**File access errors?** Temporarily disable antivirus real-time scanning during the process.

**Long reimport times?** This is normal for large projects - be patient and let Unity finish.

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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://doc.realvirtual.io/basics/user-interface/clean-restart-pro.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
