We don't know exactly what problem you are experiencing.
Please check the following cases we anticipate.
1. The first case we expect is when "Head" and "Eyes, Mouth" are registered to different control parameters, and when "Head" is selected and "Edit Mode" is turned on.
By default, when "Edit Mode" is turned on, all values other than the selected control parameter and modifier are disabled.
This is why when you try to edit "Head", other meshes like "Eyes, Mouth" are moved by different control parameters will not work.
If you want non-target meshes or bones to be moved by their modifiers and control parameters even when "Edit Mode" is on, use "Edit Mode Options".
Simply press the hotkey "D key" and the corresponding mesh or bones will be moved by other input factors.
More information can be found on the page below.
2. The second case we're guessing is that you want to edit the "Head", "Eyes" and "Mouth" meshes with one control parameter, but you can't edit anything other than the "Head" mesh.
If this is your case, it's probably because the meshes other than "Head" are not registered in that control parameter.
With the target modifier and control parameters selected, select the mesh you want to edit and click the "Add to Keys" button on the right screen.
The process of registering additional meshes in the control parameter can be found at the following link.
(If you haven't watched Getting Started yet, we recommend that you first learn Getting Started 1 and 2 through the documentation or video.)
3. In the third case, the situation you mentioned is that other meshes are not selected in "Edit Mode".
AnyPortrait makes other objects unselectable when "Edit mode" is activated for the user to precisely edit the selected object.
This is called "Selection Lock", and you can select a different target by clicking on it in the Hierarchy UI, or by disabling "Selection Lock".
The hotkey to turn "Selection Lock" on or off is "S key".
(As an aside, it is also possible to edit multiple selected meshes at once.)
As we mentioned earlier, it's difficult for us to know exactly what you're struggling with from your post.
Please check our answer above, and if the above solutions do not work, please let us know again.
If you give us more information, such as which modifier you used, how you have registered meshes in the control parameters, or if you are creating an animation, we can help you more quickly and accurately.
