How can I see in real time the changes I'm doing in Orbits > Top Rig and Bottom Rig ?

I see only when I change the settings of the Middle Rig :

On the right there are 3 orbits with Height and Radius when I change the Middle Rig it’s changing it in real time in the game play window even if the game is not running ! but when changing the Top or Bottom rig’s it’s not changing it it’s not showing how it looks like when changing the settings height and radius.

Side question how can I change the yellow small square on the left in the game view window to be in the middle of the player not at the bottom ?

Update your Cinemachine package version in the Package Manager, and you’ll have a newer UI:

If you select Top-, Middle-, or BottomRig, then your scene and game views will update to show the selected rig.

In older versions, you have to rely on the red gizmos drawn in the scene view:

The yellow dot indicates the Look At target for Composer Aim component of rigs. You can change the Tracked Object Offset in Aim for each Rig.
