I hope i'm not too late but Ashley can i suggest a better visual support for Spriter?
Like we can interact the editor and spriter files.
Spriter has become a very popular animation program used for C2, it will be great if we can do so.
That is exactly one of the primary issues when depending on third-party plugins instead of providing such core functionality built-in. I mentioned before that a built-in timeline is rather essential to have (especially seeing most of the competition offers built-in timelines).
Godot and other game dev software even have IK-animated characters as part of their core feature set, and that means no issues in regards to (visual) integration in those editors.
I certainly hope that C3 will include a proper timeline with nested timelines that allows us to at least control transformation, variables, events, path-based animation, and properties. If not, I am unsure I will update to C3, and will probably continue with (free) alternatives that do support this core feature for my upcoming projects.
