Is there a way to export the character animations, as I want to use it for a project.
Not at the moment. The character animations are still a little bit of a mystery to us, which is why we haven't been able to do any custom ones yet.
While we understand the format of character animations, we're unable to import/export them as we do not have a way to bring them to a commonly used format.
I understand if it's a bit too far out to accurately predict, but do you figure on animation editing bearing some similarities to character editing, i.e. exporting to XML or something similar and doing it in Blender? Also, is Ass_Joint actually used in any animations as far as you can tell, or is it just a unused joke bone?
