Since there have been few Chinese-style horror games, my idea of designing such a game has been around since 2018. At that time, my friend and I completed the design of the first scene and some basic operation logic. But due to my study abroad, this project was suspended until 2021 I stopped exploring AR technology and wanted to create a complete and mature work. So we restarted the project. My learning experience at OSU gave me deeper ideas and design methods. So this time I hope I can try my best to make this game perfect in a limited time. Throughout the process, I got a lot of UE4 experience. In the past, due to lack of experience, my model, material, and rendering had many problems. These problems have been improved in the new version. In addition, I have also realized the importance of optimization, and I have a better understanding of UV utilization and the use of high-definition textures. In order to better design the level and optimize the interaction, I continued to study the blueprint in depth. I also plan to continue to study rendering and real-time ray tracing after the level design is completed.
