If you have purchased the plugin on FAB then you can simply install the plugin through the Epic Games Launcher. You do not need to build the plugin yourself.
Open the Epic Games Launcher,go to your Fab Library and search for "Actor IO".
2
Install the plugin
Press the Install To Engine button, and select the desired engine version.
Installing From GitHub
The plugin is available for free on GitHub, but the free version requires you to build the plugin yourself. In order to do this you will need to generate a C++ solution for your project if it doesn't have one already.
Go to the GitHub repository linked above and download the plugin.
2
Add the plugin to your project
Navigate to your project's folder on your machine, and copy the plugin into the "Plugins" folder. If your project does not have a "Plugins" folder yet, simply create one now.
3
Compile and build the plugin
If you try opening your project using the .uproject file, Unreal will prompt you to rebuild the plugin. In order to do this, you need to have Visual Studio installed and setup for Unreal Engine.
Alternatively, you can right click on your project's .uproject file and click on "Generate Visual Studio project files". This will generate a C++ solution for your project. Once you have a C++ solution, open the generated .sln file and build the project using Visual Studio.
