Need your help to migrate assets in a project :-)

Hey guys !

I’m beginner on UE4 and i need some help for my projects. I precise it’s a personal project without any commercial use.
I’m looking for assets to use in my levels, so i’m interested by content of free editors such as Ark, D&L, Conan Exile…
But the problem is here : when i try to ‘migrate’ files to my projects, it fails. The transfer works but .uassets files don’t appear in my project content. .
Do you have any ideas to take and collect these assets ?
Thanks a lot :slight_smile:
