I’ve just downloaded and upgraded to Unity 3.4 today.
http://unity3d.com/support/documentation/Manual/View%20Modes.html, “Enabling Game Overlay will show items like Skyboxes and GUI Elements in the Scene View, and it will also hide the grid.”
It seems that the grid is based on X-Y plane on Unity 3.4.
It was X-Z plane on Unity 3.3.
See the Scene Gizmo picture on http://unity3d.com/support/documentation/Manual/Scene%20View%20Navigation.html
It seems that it is more natural to have the grid on X-Z plane.
Is there anyway to switch it like Unity 3.3?
Thanks in advance for your help.
