I downloaded an .scml animation from craftpix. How do I use it in Unity 2021.3? I have already found at least 4 GitHub conversion projects but none start. Finally I also found https://github.com/loodakrawa/SpriterDotNet which gives no errors at the start, at least in the base project, but gives various errors when I try to change animation. Question 1: how to use scml files? Question 2: If it is not possible to use them directly, how do I convert them and use the result?
