No problem :D. I’m here to help ^^.
So from what I understand you want to load an external asset at run-time into your game. This can be accomplished using pak files. Those files are group pf packaged assets that you can mount to Unreals internal file system and load at run-time,
There are several threads that will give you the required information about how to load and create those files:
- Stream an asset from the internet - Blueprint - Unreal Engine Forums
- How should we implement in app purchases? - Programming & Scripting - Unreal Engine Forums
- Streaming paks from server - Programming & Scripting - Unreal Engine Forums
It’s not an easy topic so take it with calm ^^
