Hi VallCrist !
Welcome to the forum (even if i'm kinda late on this one ! )
I saw you posted about customization and I'm facing the same "problems" you were at that time, so if you found a nice solution by now, it would be SUUUUUPER COOL if you could share it (or even point me in the right direction).
Like you, I'd like to have my "default" character in Spine editor but have all the customs equips as sprites in Unity folders
Thanks and good luck with your game :beer:
