Unreal Engine Plugin

Polygon Streaming models can be added to Unreal Engine based projects with the use of the Unreal Engine Plugin. This will allow the streaming of models with multiple millions of polygons to stream from the cloud into your Windows-based projects and applications.

Installation

Once the plugin’s zip file is downloaded from the Polygon Streaming Web Console. The “PolygonStreaming-Unreal-Version” folder should be added to the “Plugins” folder of your Unreal Engine Project.

In case the “Plugins” folder does not exist, make sure to create a new folder with the name “Plugins” and add the plugin’s folder inside. Also make sure to close your project before installing the plugin.

Create a Plugins folder within your Unreal Engine project if one does not already exist

After adding the “PolygonStreaming-Unreal-Version” folder inside the “Plugins” folder of your Unreal Engine Project. Double click your project’s file (.uproject). In case it asks you to Re-Build the project, choose “Yes” - now the project will be rebuilt and once it opens, it will have the Polygon Streaming Plugin installed.

Sometimes it may appear like nothing is happening - the Unreal Engine welcome screen may not show, but don’t worry, just give it some time for building and compiling and your project should open normally after a couple of minutes.

The plugin is only available for C++ based projects, and not available for Blueprint only projects. In case you want to use it for a Blueprint based project, first you will need to add C++ classes and make it C++ available.
