I'm having the same problem as someone else where I cannot select the green boxes in the environment on the scene view

Excuse me,

Solution is simple. In the upper left corner of the window above where it says Hierarchy there are five buttons. The first one is the "hand"(nav tool), the second one is the "multidirectional pointer"(position tool). If you have the "hand" selected you are not able to select items, and you need to switch to the multidirectional pointer(position tool) right next to it. Only than you are able to select items inside the environment.

Cheers.

Hi Daniel,

A couple things to check:

1. Are you sure you're in the Scene view and not the Game view? Sometimes I forget that I'm looking at the game view and I try to click objects, which is only possible in the Scene view. You can find this by looking for the window tabs that say "Scene" and "Game".
2. When you click on a game object inside of a prefab, Unity will select the prefab by default. You need to then click the desired object again to select that specific game object. In the video, you'll notice that before I click on a game object, I already have the Environment prefab selected, which is why I'm able to click on them.

If that still doesn't work, can you tell me which operating system you're using? I just tried this with a fresh Unity project on Windows 8.1 using Unity v5.1.3f1, imported the assets, and I didn't have any issues. Still, it could be some sort of bug in Unity.

I am on windows 8.1 and I have the same problem. I can select an object in hierarchy window, but not by clicking on an object in the scene view.

Thanks Nick for replying to Daniel's problem about selecting individual objects from the scene view. I experienced the same thing, but all good now :)
