When I turn on Rigify facial controls it fills the face with cubes and I wish I had a switch to only show the mouth controls, or just the eyelid controls, or just eyebrow controls. How do I go about doing that?
Me: I’ll just give my character a squint, oh no! That is not the right cube… undo, is this the squint? Maybe, no that’s not what I want… Maybe it’s the one above? And so on.
I could change all the shapes for all the characters but I rather it be less cluttered.
Hi, you can simply select the controls you want and allocate them to another layer.
In pose mode select the controls press M and select and move to another layer:
I’ll try it but I’ll have to check if it breaks the controllability of the Rigify panel, meaning I’ll select to hide the face control switches in the Rigify panel and it will hide them?
If you look in my image all the layers are blue on the right hand side. if you uncheck them you won’t see them. so you only see the one you select in the layer manager.
just make sure you move them to un used layer.
And they will disappear if I tick off Face (Primary) or Face (Secondary)?
Yes they will not show. you select the layers not the controls interface.
Doesn’t work, the Rig Layers panel depends on what layer the bones are placed on. If I place them on another layer I can no longer control their appearance.

You can in the layers manager. see my image. There is also away of adding controls to the control interface but i never done this.
The part you never tried before, that would be most favorable thing I’d like to learn how to do.
I find Blenders’ bone layers too awkward.
So lets sum it up; All my efforts to help you were waste of time?
No, as I’m determined to get the knowledge on how to do that and I’ll post the lesson here for all to learn. And finding what doesn’t works means I am narrowing down what can work.
you can simply use selection sets.
But I may not want use all the selections and it does not hide other selections.
In pose mode:
Alt A
Select your selection set.
Shift H after you select your set.
Couldn’t be easier.
