I am totally hungry now from all the microwave sounds.
Apart from all the tips, I see an error that pops up in some part of the video when you open the full room animation. Sometimes Blender changes so much from one version to the other that you’ll get an error at some point. In this case it’s about a directory, seems like the animation is using linked in files. That to say it’s not the same error for when opening the MacOs Files. There should be a lesson about linking on a course, you’ll eventually learn everything to do about that.
