Question Cinemachine camera 'woble' when rotating the virtual camera's target fast

Hi Unity Community!

I've got a problem with a cinemachine camera setup and I don't know what's causing the issue.

The best way to describe the issue is with a video of the undesired effect:

I rotate the cinemachine virtual camera around my player by rotating that camera's lookAt target. The problem here is that when rotating fast the camera does a 'woble' effect instead of a smooth streamlined rotation that is expected. I checked the values in the inspector and the target as well as the camera is only rotated on one axis so that doesn't seem to be the issue. You can see in the video that the yellow center marker of the camera moves down as I rotate fast, which probably points to the cause of the issue but I can't figure out the solution.

Any help would be greatly appreciated!

 

Unity version 2020.3.17f1
Cinemachine version 2.6.10 (also upgraded to latest 2.8.1 but doesn't fix the problem)

 

Thanks for taking a look, I think the problem is caused by the placing a Rigidbody on the main camera with interpolate on (that has the Cinemachine brain on it)

The reason I placed the rigidbody with interpolate in the first place is because otherwise objects childed to the camera will stutter when moving the camera.

So what would be right setup so objects don't stutter when attached to the camera if I can't add a rigidbody with interpolate?

 

Having a rigidbody attached to the camera with interpolate, fixed the problem of a stuttering effect when following a moving target. (Navmesh agent with rigidbody)

So removing it fixes the one problem but brings back the old one.

 

Try changing the update method on your brain to smart update, that worked for me when dealing with differently sourced motions.
