Lighting artifacts in Google Cardboard for iPhone

I am attempting to develop a simple game for the google cardboard in unity, and everything seems to be running smoothly, but in certain places across the map, black artifacts appear on top my models. I turned off all the lighting in the scene and that seemed to remove them. They only appear when I build the game to run it on my iPhone, in the editor it plays perfectly fine.
Does anyone know why this is happening, and how I can fix it?

Here are some screenshots of them:

 

Okay, so I've found out how to get them to go away. What was causing them was the Unity Post Processing anti-aliasing. If you turn that off they will go away.
