Ive been having a go at making plains that act as buttons, but the problem is I want to do it so that 1 3d unit = 1 pixel, for example a plain that is 96x32 in 3d size would be 96x32 pixels on screen.

One problem I ran into was the fact that they are not flat to the screen, moving the plain to the top left corner moves it further from the camera than if in the centre of the screen.

Any ideas on how to get it to work?

Cheers

Try using POINT OBJECT plainID, cameraX, cameraY, cameraZ. This might help keep the plains true since they'll tilt to look at the camera.

Another method is to move the camera way out and use a narrow field of view (FOV) value to make the camera render flat like a telescopic lens.

I could easily align them using trig and lock object, but I decided to scrap the functions because the mipmapping/filtering/etc. makes the textures either to blurry or too pixellated to be of much use. Actually, bein pixellated is good, but sometimes, depending on position, some pixels seem to be "left out" or missing, which is terrible because I have text on my buttons. I did manage to get some of them to align, but currently the functions aren't versatile enough to look good/align well.
