I am trying to create a HUD-like overlay in my Hololens project. It will not always be visible, but will only show up when you look at specific objects. It will act as a kind of help text.
I set the render mode to Screen Space - Camera. I can't seem to assign a camera however. When I try to assign MixedRealityCamera to the Camera property of the canvas, nothing happens and the field stays empty.
What am I doing wrong?
