Should be my confessed on the Mecanim Control...
I am using an asset which takes 2D Animation Clips through the Unity Animation system
So it needs a Mecanim control, and Spine has a Mecanim Control, should be working?
But I am facing a problem that, by generating the Mecanim Controller from the Spine-Unity Runtime,
it becomes just a frozen image on the first frame, instead of an animation clip in the Animation, so it does not work for me.
I can only get a animation work by baking them, but then the animation become strange, losing a lot of information.
So, really wish to know if there is a way to fit Spine clips into the Unity Animation, so I don't need to bake them?
