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 cognitive3d.com.

Step 2: Download the SDK

Our plugin is available on our Github Release page.

Step 3: Import the SDK

Note

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".

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.
