Don’t hold your breath. Spriter SCON importer is a super-early experimental WIP that I wanted to get checked into source control. isn’t an officially supported feature and won’t make 4.8 (or possibly any future version).
Having said that, it does a pretty good job of parsing SCON and has data model in memory, but there are some missing concepts or bad fits on Unreal side to flesh out, and a lot of work to make stuff like authorable from scratch in UE4 as well.
Also, mostly unrelated, but I just had to say WTF @ Spriter for allowing animated hierarchy changes… (you can keyframe bone parent changes in it, but please don’t ever do that!)
Cheers,
