The character animation is not finished but the project needs to be saved so that it can be opened and continued next time.
1. Save bones
In the case of adding only character bones, you can click to save the project.
Click [Save] in the bone editor.
2. Save the entire project including bones and motions
Click [Save] in the animation editor.
Note: If you click [Save] in the bone editor after modifying bones with a motion added, the system will clear the added motion by default; if you want to save the entire project including bones and motions, you need to click [Save] in the animation editor.
