Free Look Camera Rig Changing Rotation

Okay, So I’m making a 3d game and I use the Free Look Camera Rig provided with Unity. What I want to do is the following: If a certain animation plays, I want the Camera to basically get locked and rotate in a certain direction, lets say downwards for example. The Reason for this is, that my character is moving relatively to the camera and I want him to be forced downwards for a little (dont have gravity there) without being able to get back up. while that animation plays.

I know how to check if the animation plays and I also can change the cameras rotation, but it only works very wierdly (delayed and other wierd stuff). Is there a simple solution on how to make the Freelook Cam rig basically orbit upwards around my character for the duration of the animation?

I ended up making a second freelookcamrig (that doesnt actually work as a camera but just for math and moving relatively and stuff and changed the rotation on it with this:

mathCam.rotation =
Quaternion.Slerp (Quaternion.Euler( 35f,
mathCam.parent.transform.eulerAngles.y,
mathCam.parent.transform.eulerAngles.z),
Quaternion.Euler( mathCam.parent.transform.eulerAngles.x,
mathCam.parent.transform.eulerAngles.y,
mathCam.parent.transform.eulerAngles.z),
0.1f * Time.deltaTime);

I made the second cam so the camera wouldnt actually change and just the character movement will.
