Why UI elements are invisible on scene view?

I use unity 5.0.1p4.

Look at this screen shot. All UI elements are invisible on scene view. (wireframe visible only)


But In game view, UI element displayed well.

What should I do?

I know select layers menu in the top right corner of unity. However, I set UI layer visible. It doesn’t work. :frowning:

Try to change the scale of the ui element, sometimes it goes to 0 for no reason.

This can also happen if the UI component is not a child of a Canvas.

Try use Assets>>Reimport all
it is usefull tool and solve many problems of bugs

I had this problem, none of the above resolved the issue.

In my case, the issue was that Post Processing was selected in the scene view layers.159087-unity-ui-invisible-issue.jpg

Unticking “Post Processings” worked for me.
