In terms of the development engine, I chose Unity, with which I am familiar. Compared to other engines, Unity offers more mature and diverse options for VR development: depending on interaction needs, I could choose between XR Origin or Meta XR Tools, and it provides numerous interaction preset systems that enhance production efficiency. Additionally, to create a distorted, glowing visual effect for the scene atmosphere, I utilized Global Volume in Unity, which allows quick implementation and easy parameter adjustments to compare different effects, helping me rapidly finalize the desired scene ambiance.
For the 2D video, I mainly use Procreate and Keling AI. Firstly, painted some key frames in Procreate; then, I put those drawings in Keling AI to generate the whole video with prompts.
