I only need one view and to render it one time.

Thats the purpose of the shader. It draws the models with that background image.

Basically: I'm just changing the skin of the model to match the background image


The depth info is already there. It's very easy and works quite well. The only problem I have now is that I'm a horrible level designer

but seriously, the only problem I've run into is aligning the image with screen coords. This would't be a problem, if it weren't dependent on camera arc and resolution.

The image needs to be aligned depending on the screen resolution and camera arc. While the resolution should be an easy [linear] equation, camera arc is quadratic, and through graphing has a noticable curve... I've got to remember how to find the formula, and get more statistics...
