Character Body to Face VCam direction

Hi there, I’m a little confused as to why a simple bit of code won’t work and I’m wondering if I’m missing some key info on Cinemachine and how it works.

I have a first person cam setup, with ‘Do Nothing’ for body and Aim is set to POV. Simply, all I want to do is rotate my character in its Y rotation to match that of the camera, so the player’s body is looking at what the camera is. I’m calling this in LateUpdate()

private void LateUpdate()
{
transform.rotation = Quaternion.Euler(transform.rotation.x,   CinemachineCore.Instance.GetActiveBrain(0).ActiveVirtualCamera.Follow.rotation.y, transform.rotation.z);
}

This script is attached to the player, there’s only one CM Brain, nothing else is changing the players movement/rotation so I’d assume it would work but does nothing. To test I also swapped: CinemachineCore.Instance.GetActiveBrain(0).ActiveVirtualCamera.Follow.rotation.y for: Camera.main.transform.rotation.y …and the result was the same. Out of desperation I did a quick test and switched out the rotation code out for:

private void LateUpdate()
{
transform.forward = Camera.main.transform.forward;
}

And it works as expected (though obviously rotates the camera on all axis which isn’t what I’m after).

Any ideas where I’m going wrong here?
Thanks!

This has nothing to do with Cinemachine. The transform.rotation is a quaternion, and you can’t use its x, y, z components as if they were euler angles.

If you just want to set the yaw based on camera forward, you can do something like this:

var fwd = Camera.main.forward;
fwd.y = 0; // project onto XZ plane (won't work if camera is looking straight up or down)
transform.roation = Quaternion.LookRotation(fwd);

Ugh - of course. Apologies, and thanks!
