Using the Cognitive3D SDK for Unreal

Welcome! This SDK for Unreal integrates your project with Cognitive3D, which provides analytics and insights about your participant's behavior in VR and AR. In addition, Cognitive3D empowers you to take actions that will improve participants' engagement with your experience.

This SDK is in development and changes should be expected! Please get in touch if you experience any issues.

This plugin requires Unreal verion 4.26.2 or newer. If you are using a newer version, please check Troubleshooting.

Step 1: Sign up

If you have not already done so, please book a demo at

Step 2: Download the SDK

Our plugin is available on our Github Release page.

Step 3: Import the SDK


Your Unreal project must be a C++ project to use plugins. To convert a Blueprint Project to a C++ project, see Troubleshooting

Extract the plugin into your project directory. Rename the plugin folder to "Plugins".


Close the Unreal Editor (if it is open) and open it through the Epic Games Launcher. You should be prompted to recompile your project and the CognitiveVR Plugin. If the plugin is loaded correctly, it should be visible in the Plugins window.

Step 4: Open the Project Setup Window

From the Cognitive3D menu, open the Project Setup Window


Follow the instructions in the Project Setup Window to configure your project. You will need to have your Developer Key from the Dashboard.

Afterward, you will be prompted to open the Scene Setup Window to export your Level Geometry and upload this to our dashboard. You will also need to have Blender installed. Blender is free and open source - we use this to automatically convert images exported from Unreal Engine.

When this process is complete, you should notice a new BP_CognitiveVRActor in your level. This Actor is configured to automatically start collecting basic data.


Press Play in the Editor and you will see a new session on the Dashboard after a short delay. See Feature Overview for the next steps.
