Toon Boom includes a sample Unity project that contains all the scripts necessary to import the data exported from Harmony. Inside this project is an Assets folder which contains the following folders:
Scenes (demo scenes and a previewer)
Scripts (all Harmony scripts)
StreamingAssets (this is where all the Harmony scene files should be exported to)
By configuring the Harmony script, you can automatically export animations into the StreamingAssets folder. This way, Unity will dynamically load the most up-to-date assets as soon as they appear in the folder. You can also manually place exported Harmony data into this location.
