# Upload Content

## Uploading the Example Map <a href="#uploadingcontent-uploadingbyplugin" id="uploadingcontent-uploadingbyplugin"></a>

After [Downloading the editor](https://docs.msquared.io/creation/unreal-development/getting-started/downloading-the-tooling) and creating a project, you can test the upload flow by uploading the example maps.

Click the **Upload Content** button in the toolbar.

This button will open the upload window as shown below:

Here you can configure:

* An optional upload description, which is displayed in the dashboard.
* The levels you want uploaded. Selecting fewer levels will take less time.

Once you're done, click the **Upload** button.

For your first upload, this will open a browser for authentication - make sure to use the account you used to login to the website.

After login the upload will begin, with progress tracked in the top-right of the modal.

This button will open the dashboard page for your uploaded content, which we call a Mod.

{% hint style="info" %}
A **Mod** is a representation of your cooked Unreal content in our web platform.

When you first upload, we'll automatically create a new mod for you. Your uploaded content represents the first version of your mod. The next time you iterate and upload, that content will be listed as a new version of your existing mod.\
\
\&#xNAN;***Note** - We only store the cooked version of your assets, not the raw versions, so this is not a replacement for source code version control (i.e. you can't download your project from the uploaded assets).*
{% endhint %}

Click the 🚀 **`Launch`** button (below your mod title) to launch a world using your content.

## Troubleshooting <a href="#uploadingcontent-uploadingbyplugin" id="uploadingcontent-uploadingbyplugin"></a>

### Access to the pakchunklayers.txt is denied

This can happen if the `Build\WindowsClient\ChunkLayerInfo\pakchunklayers.txt` file is not marked as writable on your machine which in turn can happen if the `Build/` folder is wrongly checked into Perforce.

To fix this, ensure the relevant marked is **not** marked as read-only.

### **Multiple Plugins**

`LogWorldBuilderEditorUtils: Error: Multiple plugins found to upload.`

This error occurs when you have more than one project plugin *without* `M2Library: true` in the plugin descriptor.

A legacy restriction on the platform is that only one plugin is designated to be cooked and uploaded. This is no longer the case as dependencies are built from the maps selected for upload however the restriction of only one 'primary' plugin existing is still in place.

By default, all libraries created using the above flow will have this tag and *do not need to be modified* however, if you manually copy a new plugin into your project, you are likely to see this error.

To solve this error:

* Open each .uplugin file within `<your-project-dir>/plugins/` in a text editor
* Ensure that all-but-one of your project plugins have the tag `M2Library: true`
