Cause of the issue:
The port error usually comes up in 3 scenarios:
1. When the plugin was not installed in the correct location.
2. The plugin could not initialize the socket properly.
3. When you attempt to export from Bridge, but Unreal Engine is not running in the background.
- You can check if there is a green Megascans button inside Unreal Engine:
If you don't see the M button in Unreal Engine, it means the plugin was either not installed properly or was installed in the incorrect location.
Fixing the issue:
- First, close Unreal Engine. In case of a previously installed UE4 Plugin, you will have to remove the existing Plugin by following the steps in this article.
Note: If Unreal Engine is open in the background while you attempt to install the Plugin, you will get an "Install Failed" warning.
- Then, select one of your Downloaded assets in Bridge and check if the Installation Folder points to the correct location. It should be set to where your engine's plugins are installed. The default path is usually: C:\Program Files\Epic Games\UE_4.2x\Engine\Plugins, but in each case it may vary depending on where the UE4_4.2x folder is located on your machine.
- Click on the Megascans button to initiate the Plugin. This is an indication that the plugin has interfaced properly with the Unreal Editor.
- Lastly, open Bridge and ensure that both Bridge and Unreal Engine are running in parallel upon attempting to export.
