The FabricPlayerSettings scriptable object is created automatically when you add a Player component to the scene. This object stores information on what FPKs are loaded in the project, and their contents.

When selected in the Assets folder, the FabricPlayerSettings will display a list of FPKs that are currently loaded in the project.

The FPK Search Directory allows you to automatically set up a folder to store your FPKs. This path is relative to the Assets folder, and it is recommended that you create this directory outside of the Assets folder in the Unity project root folder.

If an FPK has gone missing from the FPK Search Directory, a warning will be displayed in this window. You can either re-add the FPK to the search directory, or remove any references of the missing FPK from the project by selecting Remove missing FPK references.
