AvalonXMLAgent is an agent for Plex that populates metadata using local XML files.
This StashApp plugin hooks into the Scene.Updated.Post event and writes an XML file with the same name of the movie, in the same directory as the movie that can be consumed by the Avalon agent in Plex.
When installing this plugin into StashApp, you will need to customize the LAN_ADDRESS in the Python script to handle actor images. StashApp returns image URLs with localhost and these will not be accessible if you import the metadata into a different server on your network.
This value should be set to the LAN address of your StashApp server (only use localhost if everything is running on the same server).
