I cant find how they created section_1 in the unreal course folder, is this important?
It happened in video 9. A Quick Tour of Unreal Editor in Section 1.
But no, it’s not important and you won’t be needing it to complete the rest of the course. But you should probably watch the video and do the steps so you know how the editor works and see that everything is setup right.
PS! I’ve edited this answer, as I first mentioned the wrong video.
