I was wondering if anyone experienced this issue in Unity with Mecanim-animated characters ...
I have an animated player character with a third-person camera control (Game Camera from the asset store, even though I think it isn't really related) and if the character is standing at the default y-rotation angle I can orbit around her with the camera and she will always face the same direction, as it should be.
But if the character stands with an arbitrary other transform y-rotation (for example 90.0001 or 180, etc.) and I orbit around the character, the character's Y rotation is ever so often randomly changed.
I don't know what changes the Y rotation. Game Camera doesn't touch it as long as I don't move the character so I suppose it is related to Mecanim, even though i'm not sure about that either.
I was hoping somebody has more familiarity with this issue and know what causes this. This glitch is definitely a problem in gameplay.
