When I first studied Unreal C++, I started off with a head on the ground. Because of that, I didn't have a solid foundation, and since it was so different from general C++, it was quite difficult to write code, and there were too many holes. This lecture covered things I had missed in what I had studied so far, and many functions that were not well known unlike other Unreal lectures, and there were many detailed explanations of certain functions, so I personally felt that the difference before and after watching this lecture was quite significant. It was a very useful lecture that could be considered a tier 1 among Unreal lectures.
