Don't know what Asset User Data is? It's effectively extra data you can add to (generally) any Asset or Component (or any object that implements IInterface_AssetUserData, and then can query upon at runtime. This is great for implementations where you only want to define the data once on the asset and not on a per actor basis (i.e. puzzle games).

The engine doesn't expose this to Blueprints, so this plugin does the work for you via the BPAssetUserData class and AssetUserDataFunctionLibrary.

1. Add this plugin to your project and compile it
2. If it isn't already, enable it and restart engine:
   
3. Create a subclass of the BPAssetUserData class:
   
4. Add some properties to your new blueprint:
   
5. Add an instance of your Asset Data Blueprint to the Asset User Data array in an asset or component:
   
6. Use the "Get Asset User Data" node to query asset data on reference to asset (or component):
   

The add and remove nodes should mostly be used by editor utilities and assigned once. The add node will only add a single instance of the specified class. The getters are perfectly fine to use anywhere.
