Installing your License Key

Prior to license key installation, make sure that you have completed Installing Existent Plugin successfully.

Every developer using the Existent plugin must install a valid license.

To obtain a license key, you need to sign up at the Existent website. If you have not already, you can register for an Existent account at https://existent.com/signup/.

The Existent Plugin is currently offered under 3 different licensing agreements. Choose the one that best suits your needs.

After signing up, you will receive an email with a License Key, as shown on the image below:

When you first start a project after installing the Existent Plugin, a license validation will not have been run yet, and so the Play in Editor (PIE) or Play in VR modes won't be usable.

  • Launch the Unreal Engine editor where your project is located.

  • Ensure that the Existent plugin is enabled.

  • Click on the Existent Toolbar Button and from the dropdown menu select Existent License.

    The Existent Toolbar Button contains a button to open the Existent License Settings
  • This will open up the Project Settings window (under Plugins-Existent License) and you can enter an Existent License Key.

  • After entering your license key, click on the Validate License button.

    The Existent License Settings where you can enter your license key
  • The feedback text below the button will change to show whether the license was validated successful along with license expiry date and the type of License Plan (Starter/Indie).

  • You have now successfully entered your license key for the Existent plugin in Unreal Engine. Your plugin should be fully functional and ready to use.

Troubleshooting Q&A

Q: Can I use the same license key on multiple projects?

A: Yes, each license is bound to a machine, so you can use the same key on multiple projects. You will just need to validate the license on each project. Refer to the license agreement for more details.

Q: What should I do if I lose my license key?

A: Check your email folder for the original Existent registration email. Otherwise, contact us at [email protected] and share the original email you used for registration or your company details.

Q: Do I need to validate the license key every time I start my project?

A: No, you only need to do it once. The next time you load your project, the license key will be saved and validation will take place on startup in the back-end.

Q: I tried packaging my project but packaging failed even though I have a valid license.

A: Make sure you validate your license key within your Unreal Engine project again and try re-packaging your project.

Q: How do I deactivate the license key used on an old machine?

A: When you try to validate the license key on a new machine, if the license key is valid but you have exceeded the maximum number of seats, you will see a UI menu with all currently activated machines, allowing you to deactivate old machines. You can then validate again and activate your new machine.

Q: What restrictions apply to me as a 'Starter' licence holder?

If you've opted for a 'Starter' licence of Existent, you will only be able to play the experiences you build via the Unreal editor (PIE), and cannot package your project into a separate executable file.

Any level you create must also include a maximum of:

  • 2 Existent Players

  • 2 Existent Spaces

  • 1 Existent Vehicle

  • 1 tracked object (i.e. a non-player Actor with an ExistentTrackerComponent attached)

If any of these limits are exceeded, you will not be able to play your experience via the editor.
