Many problems arose during the actual production of this kind, on the one hand the incompatibility of the scene model and the character model led to frequent errors during the animation. The inclusion of controllers failed, the program suddenly flashed back, etc. I thought about these unforeseen and unexpected circumstances and considered that it might not be possible to move forward to complete the final design on time. So I thought it would be a good idea to change the project and think further about how to refine project 1.
