Multi-User VPN Configuration and Setup (Experimental)

A short while ago, I released a video explanation of how the multi-user could be configured to work in a remote environment. This guide will be a text version of my video. If you need additional assistance, I am available via this forum, my discord and email, which will all be linked below.

Video Tutorial:

Prerequisites:

  • MUST have source control. You can use multi-user as source control, but I personally have not used it that much. For this tutorial, we will assume that you know how to use source control and configure it with this project. If you need to learn how to use source control, unreal released a webinar which can be found here: https://www.youtube.com/watch?v=faYmvw_Pd-A
  • Latest version of Unreal Engine (At time of writing - 4.26.0)
  • You will need a VPN server and client. We will guide you through how to configure the VPN system softether which we used for this guide. Other options exist so use the tools you are familiar with. Should you want to follow our guide, please download and install both the Server and C****lient tools from https://www.softether-download.com/e…duct=softether

Notes:

  • Your network speeds may be impacted, there are tricks to help solve this but you should expect slower connections while connected to the VPN.
  • It is super important that you are using the latest / same version of the project files when connecting to this VPN. If your files don’t match it will throw errors
  • At the time of writing this tutorial, this method has been tested a few times by users, however Multi-User plugin is still listed as beta and should be considered to be unstable.

Server Configuration
Please install the softether VPN server software before continuing with this

With Softether Server Manager open

  • Click New Setting
  • Choose a name, click “Connect to Localhost” and set a password for your administrative login.

Connect to the session

  • Double Click or click the join the selected session button

Working solo on the project

When working on the project solo, you must upload the projects new version to the source control. In this tutorial, we have used Github, but the same idea carries across all source control options. If you fail to upload something, and someone else starts working on the project without your updates, you are likely to have to redo whatever didn’t get uploaded to source control.
