I know I am probably doing something stupid here but while following the gingerbread man tutorial in the official on-line documentation it says that I should be able to use BKEY then left click and drag around some vertices in a cube mesh to select them. This works fine but it only selects the front-most or visible vertices but not the ones directly behind them as well.
The blender guide plus the tutorial state that it should select all vertices in the box even if they are hidden behind the visible ones, but it doesn’t. Is there some mode I need to toggle to enable this?
I am using version 2.37a (stable). Any idea where I am going wrong here?
