A bunch of stuff disapeared

Hello… silly question

Fairly new to unity… I was working on some things and I must have hit some key. I was just playing around with terrains but now no textures are showing up anywhere and also a 2d object I had in the scene is not visible. Any idea what happened? My terrain looks like the attached picture… it used to show some grassy textures and whatnot. You can also see the gizmo box around where the 2d object should be.

I assume I flipped a setting somewhere accidentally but I don’t have a clue what that setting would have been.

Nothing really obvious comes to mind… For the 2D object that isn’t showing up, if you click on it in the Hierarchy view, and look at the Inspector, did you perhaps disable one of the components? Maybe you disabled the Renderer on it?

For the material looking weird, can you click on the material and show what it looks like in the inspector? Perhaps you changed the texture somehow?

Anyway, it’s a bit hard to guess at without seeing what the inspector is showing.
