I came across this example from the 3D GUI page. As you see in this example, a 3D Manager as well as 3D stack panel with buttons are created. Yet they do not show up in the inspector window (neither as a node nor as a mesh). I am not sure who works on buttons here so I would add @Evgeni_Popov and @Deltakosh as they helped me in the past. Kindly take a look at this:
They don’t show up because they are created in a utility layer scene which is not displayed in the inspector.
I don’t know if it’s something that is worked on or not but it’s not a bug per see, it’s currently by design.
It is by design
Very nice, but how i can inspect this “utility layer” !?
Why i can see GUI but cant see GUI 3D !?
You can just call
debugLayer.show() as you do for the regular scene.
In the PG with the 3D GUI:
