Hi guys. I have found myself running into a nasty little bug. When I run my game on my computer, all the graphics show up correctly. However on some cards, especially ATI cards, only the textures I use to texture a d3dx mesh shows up. Any texture that I use to texture a quad, doesn't show up. So I guess that I am probably not building my quads in the correct way. Could you DirectX gurus take a look at my code. All this code does is create a quad and texture it. Do you see any issues? Thanks!

Do the directx debug runtimes give you any error messages?

Does the texture exceed the maximum size that the ati card can handle? Is the texture non-power of 2 in size? Is the texture of a format that the ati card can handle? If you use that same texture on the mesh, does it show up there?

You only showed the skybox code, and isn't that the code that works well? By the way, use the 'source' tag instead of 'code'. It looks better, in particular for large chunks of code.

What result do you get on the reference device?

My guess would be that you're not setting some state which works due to a default on some cards and doesn't on others, but that's just a guess.

ET3D, thanks for the heads up about the source tag.

Actually the skybox code doesn't work correctly on some cards. This class doesn't make a real skybox. All it does is create a vertex buffer quad and texture it. But it doesn't show up on some cards.

Run the application using PIX on the platform in which the textures do not show up. Do an F12 D3D call capture.

Then ensure that the Draw*Primitive call is correctly called and the vertices make it to the screen.

Next ensure that a SetTexture call precedes that Draw*Primitive call and view the texture to ensure it is the expected one.

Then debug down to the pixel level by right-clicking on the render target (likely the framebuffer) anywhere you would expect the texture should have been and choose to debug the pixel there. This should let you know why the pixel remains not colored with your texture.

At any time, right-click on the device address and review the Pixel/Vertex states to see if they are appropriate.

If you actually do any of this, it should completely remove any doubts from your mind about why the image looks wrong on a particular platform.
