After two days, I finally arrived at my new work environment. After moving home as well as doing all the work, I could continue to start my animation work.
Because there was a lot of luggage I wasn't able to bring along to my new environment, they were too heavy. I had to buy them again. So the next few months are going to be a little difficult for me...
I have to work harder and get back to my old standard of living as soon as possible.
Go for it! I hope you're like me and don't lose to all the difficulties ahead!
I actually didn't want to add Cloud because he would increase the rendering time, but I went ahead and added him anyway to fit the story of the animation.
Because of the Cycles renderer, the preview becomes very slow after each adjustment, which takes a lot of time, but the animation will be finished soon.
