I have a few textures applied to this model of a house. The textures appear perfectly fine in the viewport, and render fine using Maya Hardware and Software renders, but when I try to render with Arnold, most of the textures are horribly stretched beyond recognition (see attached images). There is absolutely no smoothing whatsoever on the geometry. The problem only occurs when rendering with Arnold, and after searching around no one seems to have an answer.
I'm using Maya 2018, MotA 3.1.2. The shading network is just a phong with a .tga texture plugged into color. I checked the UVs and the place2dTexture node, everything looks fine, including the Repeat UV attributes.
This project has a strict due date, and must be rendered with Arnold. Someone please help.

How it looks when rendered with Arnold
