— San - indeed, but I also see that you and many users get these ugly scaling artifacts. Hopefully the next version can avoid that.
There also was a question about outline and how easy or hard it would be to animate something in Spriter - this gif should provide some answers (there's a Posterization effect active on the work layer):
So basically once you have your design it would be a piece of cake to separate the parts and export them to some animation system, for example Spriter. Besides, unlike most traditional methods here you are quite likely to get edge-friendly parts (joints) simply as a side-effect of the design process.
I'm considering a feature where you can group tag selections and then auto-save all of them separately so exporting for use in Spriter, for example, would be a snap (without moving anything around).
