It went a bit better, mostly with the arms: I used separate FK tracks. I also used separate Fk track for the spine, but there’s a little bug in which f-curves don’t get updated in the Workshop when using this option.
I’m still having a hard time getting actual joints breaking.. I’ll get it eventually, but not today.
