SetViewport

Did you change the size of the window that you want your new View to use?
800x600 size etc?

D3DVIEWPORT8 *View1;

View1 = {0,0,800,600,0.0f,1.0f};
GraphicsDevice->SetViewport(&View1);

Change the size of the window? No.
Tell if I am expecting the wrong results here...
Lets say I make my app fullscreen, 1280x1024, and I want to render only to the middle 800x600 to preserve my pixel perfect art. So I would call SetViewport with:
X = 1280 / 2 - 800 / 2 (the examples I saw use the top-left corner for X,Y)
Y = 1024 / 2 - 600 / 2
Width = 800
Height = 600
Z = 0 -> 1

After I call SetViewport, shouldn't the device only render to the inner 800x600, leaving anything outside that clear color?

As I said before though, it doesn't matter what I do with SetViewport, nothing changes.

Edit: Oh, you meant the viewport window. Yeah. Thought you were talking about my Windows window.

That sounds like it should work. Are you sure you don't override this setting later on?

This is off the top of my head, but I seem to recall that SetRenderTarget also modifies the Viewport for you. I've had a look in the docs, and can't find anything about it. As a test, I'd try resetting the correct Viewport after each call to SetRenderTarget (if you have any).

Hope this helps.

Absolutely.

And you, sir, are the lucky winner of correctness.

I haven't tested it much, but I think that is what's happening. So I guess each SetRenderState call sets the viewport to fullscreen. Thanks for the help.
