terrain overlays my objects

I had some objects on my scene view (bushes and rocks) but when I added a terrain it hid everything. I heard about the selecting an object in the hierarchy window and hit ‘f’ but it didn’t work.
The objects aren’t visible even after removing the terrain again.
How can I make the objects visible again and put the terrain underneath the objects?

are you sure they all have meshes/Colliders? if not, they could be falling right through the terrain in game view… if they aren’t even visible in scene view, try creating the terrain and dragging the bushes and rocks from the project view to the scene view to where you want them in the scene

Double click the object in the Hierarchy view to focus it (F works in the Scene view, right after you’ve clicked something).

The terrain should not make your objects disappear, unless they are too far from the point the terrain is created - but double clicking an object in the Hierarchy view will bring it to the scene.

Thanks a lot for those tips! I did a tutorial and I think the objects had different coordinates than the terrain. So somehow they disappeared. At least I hope that was the problem. I try to put now everything on 0 first and then move it around. I guess the terrain usually is on (0,0,0)…
