When I create an NGUI UI, I cannot see it in Scene View. It is visible in Game view but not in Scene view. Also, in existing projects, using NGUI leads to the scene and the UI being rendered twice in existing projects when I press the play button.
in the Hierarchy View the UIroot(standardname “UI Root (2D)” object has attached a Camera (standardname “Camera”) doubleclick that Camera, the Scene View should be zoomed onto the
Ngui objects.
I just ran into the same issue - none of my NGUI objects appeared in the scene view. Turned out the NGUI layer wasn’t active for me - that was the reason. So make sure to have the layer you have your NGUI objects on active in the layers setting (next to where you can manage your layouts).
