On the positive side, the prototype has completed all required functions well, has perfect UI interaction, and has basic scene construction, but there are still areas to be improved.
However, there are still many areas for improvement, such as the lack of title placement as part of the overall architectural design. At the same time, in terms of UX, scene import also needs design, and the import time is too long.
In short, it's best to find problems in prototype, because it allows improvements to be made before the actual product is developed.
