Hi all,
I am following the youtube 3d tutorial, at 3:39 that I can select the GUI System: Default Unity UI. But in the latest version, there are no way to select GUI System...
I want use unity default UI system..., where can I find the default Unity UI Prefabs?

It's on the Page 7, the "Review choices" page, just before you click "Create" to generate your Managers.
At the bottom of the Main settings panel, you have a "Default interface" option.
Even if set to its default option, Adventure Creator, you can still use Unity UI for your generated Menus - just set their Source values in the Menu Manager to Unity Ui Prefab.
Oh, get it! Thanks!
