# Upload a Space

## What is a "Meta Space"?

Meta Space refers to a virtual world where other users can interact with one another. It's like a level in a game, or a simulation. A place where you can move around, interact with things, and explore.

Before getting started, make sure you've properly [installed the SDK](how-to-install-the-sdk) and [created an account](create-an-account)!
{% endhint %}

1. Open the Demo scene located in `MetaverseCloudEngine/SDK/Scenes/Demo.unity`

![Select the Demo.unity scene.](https://user-images.githubusercontent.com/14853489/183641458-d165ebc2-1349-4d5c-9d6a-ec152f6ba25c.png)

2. Click play to try out the scene in local test mode.
3. Once you're ok with the level you've made, select the "Meta Space" game object from within the scene hierarchy.

![The Meta Space game object is in the scene's hierarchy panel.](https://user-images.githubusercontent.com/14853489/183641725-04bf2e4a-40a9-45c8-ae8d-41831910ea5a.png)

4. Then from the Inspector window, expand the "Meta Data" dropdown to view / change the space's name, description, thumbnail, etc.

![Expand the "Meta Data" tab to see the meta space metadata.](https://user-images.githubusercontent.com/14853489/183641880-71c6de4c-a386-4447-b027-e4ef0dc299f5.png)

5. After you're done changing the meta data, you can click on "Build & Upload" to finally upload your scene to the REACH Explorer.

![Click "Build & Upload" to upload the space.](https://user-images.githubusercontent.com/14853489/183642143-f3a26d33-51c7-4527-b36d-e5d739bcc47f.png)

{% hint style="success" %}
Once finished, you've successfully uploaded your first Meta Space. You can view your space from within the REACH Explorer app (under the platforms you selected).&#x20;
{% endhint %}

{% hint style="info" %}
By default, all spaces are unlisted, so you'll have to log in with your uploader account to view the space on the public dashboard.
{% endhint %}



## Requirements for Building to Other Platforms

To build for other platforms, you must install the corresponding modules for your Unity Editor installation. If you don't add these modules, you will not be able to build to those platforms. You can add these modules from the Unity Hub "Installs" tab, adding them to your specific Unity Editor version.
