    Is there any way to smoothly rotate the camera when world up changing? Or at least keep the camera position after change.

    Right now, I created a dummy gameobject that smoothly rotates like player (which is used to override). But I would like to avoid creating unnecessary entities.

    Can you show a picture of your vcam inspector?

    Your setup is wrong.
    You need to have the main camera with the Brain as one top-level object, and the freeLook as another. Each vcam is a separate game object, and the brain will track the current active one.

    Thanks for the help, but it still does not work -_-

    Now I have two separate top-level objects:
    MainCamera (Brain, World Up - None)
    CM FreeLook (FreeLook and Camera Up Extension script)

    PostPipelineStageCallback is invoked and state.ReferenceUp = myTarget.up is changed, but during the next invoke it contains default value and Free Look Orbit in editor does not change its rotation.

    It looks like something overwrites it. I have already tried a new clear scene - all the same.

    I made a quick scene to test it with a free look. It seems to work.
    What versions of Unity/CM are you using?
    What is the binding mode of the freeLook?
    Is the target objects a separate game object?

    @Gregoryl
    Unity 2019.1.2.f1
    CM 2.3.4
    FreeLook binding mode: Simple follow with world up
    The target is separate object that can move & rotate.

    For testing I created a new scene only with the most necessary.

    This is how the free look camera orbit changes if I set my target in MainCamera (CM Brain) -> World up. This I am trying to achieve, but with my control of smoothness.

    And this if I set world up only through a script (just state.ReferenceUp = myTarget.up;):

    Can you send me the scene? Ideally, exported as a unitypackage. That will save us some back-and forth.

    If you're just trying to have the up match the target, then a good option is to use LockToTarget binding mode, which sets the vcam's up properly. Then you don't need the custom up script.

    Use damping to keep things smooth:

    Thanks for sending.

    So in fact it's working - the red gizmo is just drawn incorrectly (it's a bug in the Gizmo Drawer for the FreeLook - we will fix it).

    I do think you'll get better results with the LockToTarget suggestion I made above. Would that approach work for you?

    Are you sure? Because when I try to move the camera, it moves and stops exactly in gizmo, regardless of the current target rotation.

    Unfortunately, this does not suit me. Without going into details - I need to smoothly change the world up only at certain moments, not all time.

    Anyway, thanks for the help. I think in my case my initial decision will suit me: dummy object which I use to override world up and just rotating it at the right time for me.
