Hello,
We use Spine for our game made in Unity.
I've encountered a curious behavior in the transition between the moving state and Idle state for a character.
It seems to be the IK keys the problem because I animated with IK for the Idle animation but in FK for the Walk and Run animation. At first, the interpolation is fine but after un little time something "break" and the interpolation is all wrong with the legs making 360° during the transition.
I've made a little video to show you this weird behavior.
It could be fixed by setting Auto Reset in Mecanim Translator to true but the transition becomes then really rough.
