The ViewModes toolbar helps save time when debugging issues in your scenes.
To activate the ViewModes toolbar in CRYENGINE Sandbox, right-click on an empty space in the toolbar area. This will open a menu that will allow you to add additional toolbars to the UI .
Select ViewModes from the drop down menu and you will see that the ViewModes toolbar has been added to your Editor's UI.
This toolbar has been introduced to save you time by not having to remember a large number of CVars and commands.
From left to right, all the buttons in the toolbar have been listed below along with a description of what they do. Additionally and for your reference the CVar being modified has also been included.
All but one of these buttons are toggles, on/off. Others, like the min_LOD will cycle between 6 options (0 -> 5) & back again to 0.
