I got some map assets off the web, and just wanted to ask before I made any rash decisions, which folder should I put them in?
People don’t usually add things directly like that. Usually you would import them in the editor.
Open your UE4 editor and go to your content browser. One of the options at the top should say “import.” Go to whatever folder you like and then click import. Then all you have to do is find the asset you want to add and click “open.”
