    Hello, hoping someone can help.

    I have been trying to have a Virtual Camera follow a group of targets using the CinemachineTargetGroup component, however when I move a target far enough out of the screen, the Virtual Camera does not move or zoom enough envelope the targets.

    Here is the issue

    Here are the Vcam settings

    Your problem is here:

    You have clamped the minimum and maximum FOV to 3 and 60. It will not zoom more than that. You can try changing these settings.

    Hi @Gregoryl

    Thankyou very much for the quick reply.

    I tried to maximise the FOV and unfortunately had the same problem. I then tried to use the "Dolly Only" (which I expect would only move the camera backwards to fit the objects in view). Although the effect was better I still was able to move one of the targets out of view:

    Here are my new settings:

    There was a bug in the Group Framing that was fixed very recently, and it might be contributing to this. The fix isn't released yet, but if you would like to send me a simple project that shows this problem, I can check it against the fixed version and see if that's the cause.

    Thanks @Gregoryl

    I have attached the sample project.

    To reproduce, move one of the bottom cubes out of the screen by reducing the Z transform value.

    Thanks for the upload. I can confirm that the bugfix does correct the framing issue.

    However, it is still possible to drag the objects to such an extreme that the setup will give up trying to frame everything. There is only so much that the algorithm can do.
