[Rookiss R&D Lab] UE5 Framework Insight (Liu)

He teaches the overall structure and engine flow of Unreal Engine in a way that's easy for students to understand in the necessary direction. When studying Unreal Engine, there were times when I became curious about the engine concepts and the overall creation order of classes. However, when I actually tried to look into it, I was often overwhelmed by the vast amount of code. But in this lecture, he appropriately cuts down that vast code and explains only the parts that students need, so it was really great how he explained and helped me understand the necessary and appropriate things in engine code where it's easy to lose your way and direction when studying alone. Engine code that could be very difficult if you just look at the code, but through conceptual lectures consisting of diagrams, he first helped me understand the concepts in the areas I needed to learn and then explained the code, so there wasn't much difficulty. The length of each video is also short, so there's no burden to start. If you want to understand Unreal more deeply and apply and utilize it, this lecture seems to be a must-take course.

Please explain the overall flow of Unreal along with the code. I was able to analyze complex code well and learn step by step by dividing it into parts. The flow of concept learning using ppt -> code learning made it possible to understand difficult and challenging parts. Various examples were provided in the concept lectures, making it easier to understand. Highly recommended for those who want to learn about Unreal's internal operating mechanisms. The ppt illustrations are really cute..

The pictures with perfect analogies and clean explanations are incredible. The effort put in is unimaginable.

The explanation of Unreal Engine's source code focusing on the core parts from a big picture perspective in an intuitive way makes it easy to understand.

This is a well-structured lecture that makes it easy to understand Unreal Engine concepts and code together. At the beginning of the lecture, learning objectives were presented first to show which concepts to focus on, making it easy to set direction, and by separating concept parts and code parts in explanations, I was able to follow complex content without burden. Particularly in code explanations, rather than just simple usage, they pointed out why Unreal chose such structures, which helped understand the overall flow. Also, when difficult concepts appear, instead of jumping straight into code, they first organize concepts using PPT diagrams, then help you understand what role that part plays within the overall code flow. Thanks to this structure, it was easy to grasp what context the current learning content is in, and understanding the overall structure became faster. At the end, they provide a simple summary of the learned content, so it was good to reflect on which parts I focused on studying in connection with the initially presented goals. I recommend this lecture to those who want to understand Unreal's structure and operating principles together rather than simply following code.

This lecture covers the fundamental aspects of Unreal Engine that we unknowingly take for granted in our daily use. It extracts only the core code from Unreal Engine's incredibly complex source code and explains it in an easy-to-understand manner. For parts that are difficult to understand just by looking at the code, separate concept lectures are provided so there's no difficulty in following the course. Personally, I think it was good because the lectures are generally short, so even when covering difficult content, the lectures don't drag on. I would recommend this lecture to those who have tried to understand Unreal Engine source code directly but gave up due to the vast amount of code, or to those who are seriously curious about what Unreal Engine looks like internally and how it operates.
