I'm new to Maya, but I'm having this frustrating problem. My object looks great in the persp view, and my cameras are working fine, but whenever I try to render out my move the textures of the object become jagged in the final product.
Here are the before and after pics.
Looks like you have a little too much bump or displacement in the material? If using displacement in mentalray try setting the displacement values in the Mentalray approximation editor under Window-->Rendering Editors
if bump bring down the bump depth value in hypershade or alter the contrast in your bump map.
