I have been using the spine animator with unity for some time.
This works great because of the runtimes. Sadly no runtimes for UE 4 exists. But thats not too bad, cause UE 4 is so powerful.
However, the question which I have now is: Is it possible to apply skeletal animation i.e. set bones and rotate, translate them, on 2d sprites in UE 4?
Or do you have to have a 3d mesh to animate it in such a way?
I am new to UE 4, so I hope my question makes sense.
