Question Transitioning from VCam to FreeLook sometimes shakes randomly

For some reason when transition from and to the FreeLook camera weird rotation jitters happen, they are sort of reproducible but sometimes they don't happen at all in the same circumstances.

I'll attach a video and the two components this specific instance is happening, but in my project, it happens nearly everywhere at random, but only with the FreeLook camera.

Also here are Screenshots of the Main Camera with its components, the FreeLook camera, and the Virtual Camera.

The Free Look Transition is set to Screen Space Aim When Targets Differ and the transition is done inside a timeline.


Thanks in advance for any help,
Best wishes,

Hey Gregoryl,
1. The camera look at target is in front of the player, i'd say about 4 units, it Is animated through the timeline.
2. I will check without the collider soon and get back to you on that one.
3. I'm using Cinemachine 2.6.3 and unity 2020.2.0

 

Sure, it would be similar to this. I also checked with disabled collision, same issue.

I have run into this issue at a bunch of places, just so you know. It's not a one of to this location.
Thanks again for taking a look!

 

Tried disabeling them but no impact, I caught the event in editor mode and saw, the vcams where stable, it's just the main camera that's jittering

 

Sorry, yeah in retrospective the image was pretty bad
I tried recreating the issue with no real success, I caught the event in edit mode though, and was able to traverse through it step by step, I added markers to all the important objects. (Pink is the FreeCam, yellow the Vcam of the timeline, the magenta diamond I the look target of the vcam, and the player tag is the target of the freecam)

I hope this brings some more insight into the problem!

 

Sure, here's the hierarchy, or the important bits at least, I will try unparenting the freelook cam from its target, to test if it still happens!
Edit: Tried unparenting the Freelook, didn't make a difference.

 

I have the same issue, but if I use Fixed Update for Update Method on CinemachineBrain, it's better.
Not sure about other options, but maybe it's your case too.

P.S. I used to have this issue with Smart Update.

 

I think I did that once in the past but it didn't work. Anyway, I tried it again, but sadly this didn't fix the issue either.
Thanks for the suggestion though!
