If you have a custom game engine, you can take the exported Harmony data and proceed with your usual process. Or you can modify the export script to fit your convention.

Before exporting a scene:

• Be sure to set your Display as Display and not Display All.
• Be certain to save your scene. Harmony makes the export based on the tvg files, any unsaved updates you have added will not be exported.
• Set your Harmony scene to be a square resolution (ex. 1024 x 1024). Select Scene > Scene Settings.
