# Validate your project settings

The **Odyssey Validator** is an editor utility that helps you successfully deploy your project when using features like [instant-multiplayer](https://docs.odyssey.stream/instant-multiplayer "mention")or [realtime-configurator](https://docs.odyssey.stream/realtime-configurator "mention").

It tracks your project settings for correct implementation, and suggests auto-fixes when an issue arises.

{% hint style="info" %}
Run the validator each time before you prepare your project package. It will help you catch issues that could result in packaging or runtime errors.
{% endhint %}

## Running the validator

The Odyssey validator will run for you in the background to check your project settings as you make changes. You can also run it manually through the **Odyssey toolbar -> Validate Odyssey Configuration**.

## Letting the validator auto-fix issues

As you begin using Odyssey features like [realtime-configurator](https://docs.odyssey.stream/realtime-configurator "mention") or [instant-multiplayer](https://docs.odyssey.stream/instant-multiplayer "mention"), the validator will step in to help you.&#x20;

After enabling one of these features in your project, you will see the validator notifying you that there are settings that need to be changed:

You can use the validator to hot-fix these issues:

1. Select `Inspect Errors` on the validator notification Or, go back to your main World Editor window and open up the **Message Log -> Odyssey Configuration Validation**:<br>

2. In the Message Log window, you will see all the issues reported by the Odyssey Validator. Click on the **Fix** hyperlink next to the message:<br>

3. The auto-fix window will list all changes it wants to make for you. Click Continue to let it run the auto-fix scripts:

4. After continuing with the auto-fixes, you can rerun the validator. If fixes were resolved the validator should now succeed.

{% hint style="warning" %}
In C++ projects some of the auto-fix options are not available.&#x20;

In these cases the validator gives you detailed information on what changes need to be made in your C++ codebase.
