Under the new media era, the film and television post-production technology is changing day by day, in order to explore how to utilize the powerful functions of the Unreal Engine for the production of mythological themes in film and television. This paper in-depth study of the specific functions of the unreal engine on the film and television creation of help, analyze the evolution and development of the creation of mythological themes, put forward the problems it faces. Based on the creation needs of unreal engine and mythological works, this paper uses unreal engine to adapt Lu pan from Liaozai to explore its complete production process, and the production results show that unreal engine greatly improves the quality of the screen and the presentation effect, reduces the cost of the film's production, and improves the collaborative ability of the production team and the ability of creativity. However, the production process still requires high hardware equipment and paid plug-ins for Unreal Engine. We provide the establishment of the process for the combination of Unreal Engine movie and television production and mythological theme re-creation, supplements the production details, and provides suggestions for its further improvement.

The Unreal Engine is a free game engine developed by Epic Games. In this paper, we propose a First Person Shooter (FPS) game development using free Unreal Development Kit. The merit of Unreal engine provide a hight degree of portability, and it is a tool used by many game developers today, supporting a multitude of platforms on personal computers and many video game consoles with free toolkit. But it is required high-performance PC to develop game. This toolkit doe s not high-quality computer programming skill, just possible to develop FPS game easily.

본 논문에서는 언리얼 엔진4의 Behavior Tree(행동 트리)를 이용하여 NPC의 다양한 상태와 움직임을 가진 어드벤처 게임 AI를 설계 및 개발하였고, 그 효율성을 분석하였다. Behavior Tree는 상태와 행동을 계층적으로 나누어 AI의 행동을 결정하는 알고리즘으로 FSM(Finite State Machine, 유한상태기계)과 비교하여 유지보수와 행동 규칙 검증의 어려움을 해결하는 데 장점이 있음을 확인하였다.

최근 가상현실을 활용한 게임콘텐츠들이 많이 제작되고 있다. 그러나 킬러콘텐츠가 부족한 상황이며 가상현실 게임을 즐기기 위해 사용하는 HMD(Head Mounted Display)는 멀미감 때문에 장시간 사용하기 힘들다. 본 연구에서는 멀미감을 최소화할 수 있는 퍼즐과 요즈음 오프라인에서 인기가 있는 방탕출 게임을 동시에 즐길 수 있는 콘텐츠를 제안한다. 특히, 개발한 콘텐츠는 Unreal Engine을 사용함으로서 게임에 현실성을 더욱 가미할 수 있었고 남녀노소 누구나 즐길 수 있는 범용적인 콘텐츠이다. Unreal Engine을 활용한 게임이 별로 많지 않아 본 콘텐츠는 향후 Unreal Engine를 활용한 게임을 제작하는데 도움이 될것이라 사료된다.

Recently, the use of Unreal Engine for animation production is increasing. In this situation, Unreal Engine's 'MetaHuman Creator' helps make it easier to apply realistic characters to animation. In this regard, we tried to produce animations using 'MetaHuman' and verify the effectiveness and differences from the animation production process using only Maya software. To increase the efficiency of the production process, the animation process was made with Maya software. We tried to import animation data from Unreal Engine and go through the process of making animations, and try to find out if there are any problems. And we tried to compare animations made with realistic 'MetaHuman' characters and animation works using cartoon-type characters. The use of the same camera lens in realistic character animations and cartoon character animations produced based on the same scenario was judged to be the cause of the lack of realistic animation screen composition. The analysis revealed that a different approach from the existing animation camera lens selection is required for the selection of the camera lens in the production of realistic animation.

Research on the visual narrative impact of Unreal Engine's Lumen lighting system in games aims to delve into how Lumen's lighting technology plays a crucial role in game design and gameplay experience, thereby enhancing the visual storytelling of games. Lumen, Unreal Engine's dynamic global illumination solution, calculates lighting and shadows in real-time during gameplay, creating a more realistic and immersive environment. Analysis indicates that Lumen technology not only provides visually realistic and dynamic lighting effects but also significantly enriches the expressiveness and immersion of the game narrative through its changes in light and shadow.

There have been many studies to improve the efficiency of the CG production process, but it was not easy to overcome the problem that it was difficult to check the result in the middle of work and it took a lot of time for rendering. However, as the possibility of using Unreal Live Link, which can check the result in real-time, is increasing, expectations for improving the efficiency of the production process are rising. This study analyzed the efficiency of the 3D animation production process using Unreal Live Link. To this end, modeling, rigging, animation, and layout work were done in Maya, and the final output image sequence was rendered in Unreal Engine through Unreal Live Link. And the difference between this production process and the existing production process in which the final output image sequence is rendered in the 3D software itself was compared and analyzed. As a result of the analysis, unlike the traditional 3D animation production process, it was possible to check the final work result in real-time by proceeding with the work through a high-quality viewport screen, and it was found that the efficiency of work was maximized by deriving the final result through real-time screen capture. Recently, the use of game engines in the 3D animation and film industry is gradually increasing, and the efficiency of work is expected to be maximized if Unreal Live Link is used.

This paper analyzes performance difference between Unreal Engine's built-in network solution and IOCP server. To do this, we developed IOCP server and 3D game with Unreal Engine 4. Also we considered the game variable obfuscation program to prevent the modification of the memory of the code-modulated game hacking program. This paper used SCUE4 Anti-Cheat Solution, which is Unreal Engine's solution, to study preventing memory modification and to analyze performance trade-offs.

The platform for displaying cars has been changing with the times. From the popularity of paper media to the rise of computer graphics, the improvement of technology has brought more space and possibilities to the automotive industry. Yiming Zhong proposed the workflow of car configurator through Unreal Engine 4 to implement the basic functions of configuration in 2021, according to Yiming Zhong's final presentation, there is still room to improve the realism of graphics and functionality of the car configurator. Therefore, in this paper we propose to upgrade the car shaders and lighting environments according to the real-world physics and add multi-scenes switching function to car configurator. However the multi-scenes switching function also brings a large amount of data, which leads to the problem of display lag. At the end of the paper, we use the level of details(LOD) process to reduce the amount of data for real-time computing in Unreal Engine 4 and the increase of frames per second(FPS) values verifies the feasibility of our optimization solution.
