anti-aliasing in mental ray.

Is there any way to turn it off in 3dsmax?
The reason I want to do this is mental ray can render the ink and paint material properly from an orthographic view,( something the default scanline renderer can't) but I want my renders to come out clean with as few colors as possible for sprite making so I can have an easier and much more controlled time color indexing as well as making alpha maps without any wierd artifacts.

I've tried manipulating the perspective view with the default scanline renderer to being pretty much orthographic but it ends up rendering with tons of errors.

Thanks in advance.
