Support means that if an artist decides they want to create multiple poses for the same character, similarly how the hands work in the Throne Lady pack, they are now able to. Obivously this doesn’t affect any of the existing packages, since all new sets (poses) are needed to be rendered separately. This development just opens up the option for any future packages to have more flexibility, which we didn’t previously have in Season #1 and Season #2.
As for the tutorial, that’s where it ends. If you haven’t completed it earlier you’d get a messagebox saying that your free pack is unlocked. Since you did that already, you are free to move on from there. I could add a messagebox there saying something about that too. I didn’t realize it’d be confusing, good point, thanks!
