What does UMotion project is used for?
I just considered it as a general project file such as VisualStudio so that it stores Config settings.
After a lot of trial and error, I doubt that the unique information that has been previously worked is stored in. In other words, even though the GameObject is the same, it should not be used continuously as a single project file, and it seems to have to be created every time the animation changes. Whenever UMotion behaves abnormally, I created a new project file and there was no such a problem.
