I don’t know if any of you guys saw this tool for 2D stuff but it’s pretty much the same as SPINE that Unity have just for creating 2D games and animations in 2D. Is now available for MAC and soon for Windows!! Just check this out, it looks real good!
It is supported for UE4 :)!
Thanks to this guys to release this tool for UE4, I was jealous watching all those Spine’s videos for Unity and Cocos on YT :p!
Check their website and demo videos!
