Troubleshooting Unreal SDK

This page explains how to resolve common packaging issues in the PubNub Unreal Software Development Kit (SDK), including the plugin loading error for Blueprint projects.

Package a Blueprint project

Because of a bug in Unreal Engine, sometimes C++ plugins fail to load when you package your Blueprint project.

To resolve the Plugin X failed to load error, you must create a C++ source file in your project otherwise the plugins are going to be excluded.

To resolve the plugin error when building a Blueprint project:

1. In your project, create (Tools-> Add C++ Class) an empty C++ class with None as the parent.

2. Remove the Intermediate, Build, and Binaries folders and rebuild the project.

3. Reopen the project.
