I believe this has been asked in a similar way before, but I've been running into this issue quite a bit. I work for a game studio and Im creating new animations for existing assets. I want to copy an animation of say an 'explosion' into a new spine file I'm creating of say a 'soldier.' The only way I can seem do this is to import as a new skeleton. This won't work for my current use as I need these two things to be on the same skeleton so the program will call only one animation and not have to call two (not to mention it would be currently impossibly to test on my test engine). Is there any way around this? Or is it set up to only import skeletons/ animations while ONLY creating a new skeleton? It would literally save me hours of work to have this solved. My only fix right now is to re-animate everything so its in the same skeleton. Super confused and would love some advice! Thanks!

I see the usefulness of having two skeletons for some projects, its just so weird that its the ONLY option that I can find! Its super difficult to have an animation right there, all done, that I have to re-animate because:

A.) its in a different spine file
B.) you can't copy paste animations from one file to the next
C.) you can only import onto a new skeleton which doesn't work if you need these two animations to be attached.

Also is there a way to have two spine files open at the same time?
