I'm trying to 3d matte texture geometry by projecting a photographic image onto some simple models. 
One of the objects needs two different projections, and I have assigned two separate surface materials to the two different sides of a shed
that I want to texture separately. Problem is that, while the perspective projection from the image plane camera is fine, the other planar projection image is tiny in the UV editor and is tiled, covering the whole face in tiny pictures- when I only want one image projected onto it. 
(I know that my geometry is HUGE because I began working in large proportions in the beginning because I thought it was affecting my focal length/perspective, so maybe this is why the image appears so small in relation to the face of the model.)

I've tried to just work this out with trial and error, but it proves difficult on something as complicated as maya hehe. I'd love to hear any solution to the problem! Thanks
