      • I'm hoping someone can help me get antialising working in my game. I figured out that when rendering directly to the screen I can set antialiasing using these fields at the top of my render function. myDevice.RenderState.MultiSampleAntiAlias = true ; myDevice.PresentationParameters.MultiSampleType = MultiSample.SixteenSamples; myDevice.PresentationParameters.MultiSampleQuality = 8;

      • Hi all, I've been playing with JimJam's excellent Mercury Particle System, which you can find at http://www.codeplex.com/mpe . After a few hours of hacking, I managed to get the system running on the Xbox 360. I modified the example so that you can hold the A button down on the controller and draw a stream of particles with your joystick. Unfortunately, my expectations of the 360's performan

      • I just want to make a simple per vertex fog with XNA, I thought, it will be easy, but... The problem is: if I set everything correct (I think), only the objects get the fog, not the scene/ screen! But why I set this parameters: FogEnable = true; FogColor = 1.0f; And I use the FOG semantic in the vertex shader: OUT.FogD = saturate( (fFogEnd - d) / (fFogEnd - fFogStart) ); So why happen th

When i now render this TriangleList, it's hidden behind any sprite on the screen.
