Confirmed. Setting the "Shake/Shake Speed" value to 0 on the Camera Controller component solves this issue. Screenshot attached.
Note: this is on the camera object, not the player object.
I'm trying to stop the camera from following the head bone during idle animations. In other posts you suggested setting "Smooth Head Offset Steps" to 0. That doesn't work, or at least it doesn't in version 2.1.5 . I've tried this in my game and in a separate project with just UCC using the demo...
