I want to render a sky in background of all my geometry. So I tried to set viewport MinZ and MaxZ to 1 (like it says in DirectX SDK documentation) but I still have geometry behind like if z was not to 1.
If I change my vertex shader by changing z position to w it works.
Any idea why it does works with the viewport ?
