First off, I just want to say how awesome this program looks. I’ve been interested in Spine and programs like it for a long time now, and they either cost a huge amount of money, or lack the features I’m after (mesh deformation, IK, etc.)
My only uncertainty is the Unity runtime. Does the Unity Runtime import your sprites along with the skeletal structure of your mesh? Or does it just export our image sequences/sprite sheets. One of the biggest advantages 2D skeletal animation has over traditional sprite methods is animation blending, and I want to ensure that is preserved before I jump into this!
