Hi @Erika! Thank you very much for your reply, it is just what I was looking for!
After reading the documentation and watching some videos, I've been applying this tool to all the models in my game that can benefit from this (for me) new functionality. However, I'm having issues with ONE specific object, and it's that once I add the Skeleton Separator, the animations stop playing. What could be the reason for this?
This object has a "sibling" that is exactly the same in every aspect, except for the spine object (they use the same script to manage logic, the same script to manage animations... everything is the same except for the spine object), however, one plays perfectly and the other doesn't.
I've been reviewing everything, step by step, and I always get the same result. Could you help me with this?
EDIT-UPDATE: I just realized that enabling the Mesh Renderer enables the animation (but keeps the object as "one and only layer"), however, the other object has it disabled too and works just fine anyway...
