GetComponentsInChildren Not Working As Expected

Unity Engine

So it’s only outputting the parent. I actually want this, but it’s not outputting the children:

I’m using unity 2018.2.10f1. But it should be exactly the same in this case.
Code:

foreach(Transform obj in meshUI[0].GetComponentsInChildren<Transform>())
            {
                obj.gameObject.SetActive(true);
                Debug.Log(obj.name);
            }

What am I doing wrong?
EDIT: sorry I forgot some info: where is says meshUI[0] that is just the GameObject PN Settings

is your object originally inactive? GetComponentsInChildren() won’t search inactive GameObjects. You will need GetComponentsInChildren<Transform>(true) to include inactive children.

Take a look at the documentation of GetComponentsInChildren().

Keep in mind that using GetComponent() and its kin (in Children, in Parent, etc) to try and tease out Components at runtime is definitely super-duper-uber-crazy-Ninja advanced stuff, to be avoided at all costs unless you know exactly what you are doing.

If you run into an issue with any of these calls, start with the documentation to understand why.

There is a clear set of extremely-well-defined conditions required for each of these calls to work, as well as definitions of what will and will not be returned.

In the case of collections of Components, the order will NEVER be guaranteed, even if you happen to notice it is always in a particular order on your machine.

It is ALWAYS better to go The Unity Way™ and make dedicated public fields and drag in the references you want.
