Unity's Export to FBX Messing with eye's

I have a model with textures and whenever i try to export as an FBX using Unity’s Export to FBX it makes my models eye textures vanish and the eyebrows go weird too. I have no idea why and can’t seem to find a solution to this anywhere i look? I want to export as an fbx so i can rig the model for animations. (I’ve tried embedding textures, Ascii and Binary)
