Installing and updating the OKO Unreal plugin

Version 6.3.0 - CSP 6.48.0 - UE 5.8


This article will guide you through the installation process of the OKO Unreal plugin. We will show you where to download it and how to install it in your version of the Unreal Editor.

Instructions

First of all, if you don’t already have an OKO account, head over to https://app.oko.live/ and sign up for free.

To download the OKO Unreal Plugin go to https://app.oko.live/downloads and click on the Unreal Engine button that corresponds to the version of Unreal Engine you are using:

Magnopus always supports 2 versions of Unreal Engine; the current version (it may take a few weeks for us to update to the very latest version of Unreal Engine) and the previous version.

This will download a compressed file, okoplugin_win64.zip,to your downloads folder. Before extracting the contents of the zip, head to Unreal and open a new project.

Once you have created the project, go ahead and close it. You should now see a folder for that project in your file explorer.

Open your Unreal project folder and under the main directory create a new folder called “Plugins” (if not already present). Inside “Plugins”, you may already have folders called “OKO” and “OKOMcpTools”. To avoid any issues with stale files, you are advised to delete them.

Access your downloads folder and extract all from the zip.

From here you can copy the “OKO” folder from the extracted files into your “Plugins” folder. If you are using Unreal Engine 5.8 and you want to take advantage of the OKO MCP Tools, you should also copy the “OKOMcpTools” folder. 

OKOMcpTools is currently only available for Unreal Engine 5.8 and above.

Open the Unreal project once more, go to Edit > Plugins and make sure the OKO plugin is enabled.

Note you may also see the OKO MCP Tools plugin. If you want to enable that as well, there are a few more hoops for you to jump through. You can follow the steps here.

You will now be taken to a web browser when you sign in using your username and password for your OKO account.

Once you see this screen, you can close the tab and go back to Unreal Engine.

All good!

Congratulations, you have successfully installed the OKO Unreal plugin!

Updating the OKO Unreal plugin

How can you tell if you’re using the very latest version of the plugin? Well, you can either delete your Plugins/OKO folder (and Plugins/OKOMcpTools folder) and start the installation process again. But there’s no need to do this, as the plugin checks the version number whenever you sign in. If you’re using an older version and you want to update, you can make a choice with the dialog box that appears once you’ve signed in.
