First, I wanted to make sure I'm implementing my split screen correctly. I have an array of cameras and each camera stores not only its location but also its destiation rectangle on the screen. So my loop basically goes as follows: device.BeginScene(); device.Viewport = ViewportFromCamera(camera[0]); device.Clear(ClearFlags.Target | ClearFlags.ZBuffer, colorToClearScreenTo, 1.0f, 0); DrawScene(camera[0]); device.Viewport = ViewportFromCamera(camera[1]); device.Clear(ClearFlags.Target | ClearFlags.ZBuffer, colorToClearScreenTo, 1.0f, 0); DrawScene(camera[1]); // etc device.EndScene(); device.Present(); The problem is that my zBuffer seems to not be working when I am using viewports. If I remove all other cameras and use only one camera, and never explicitly set the device's Viewport, then the ZBuffer seems to be working perfectly. Even just keeping it at 1 camera but setting the viewport to the full screen messes up the ZBuffer. Am I missing something here? --Vic--
