Custom shader remove shine

Question

I'm quite new to shaders and have written a very simple one for low-poly terrain, however when viewed at an angle the faces get a sort of white shine. After some research, people have said that if you set alpha to none on a texture, unity just interprets that as white alpha. I don't want any sort of brightness added to my textures at an angle, only shadow. alt text It is my understanding that smoothness and metallic are set to 0 unless specified in a custom shader, so I'm not sure how to go about fixing this. Would it have something to do with alpha cutoff? I have no idea.

Assuming this is a surface shader, it will probably be using the Standard lighting model by default, which is physically based. As part of this, in reality no object is perfectly diffused, so a small amount of specular lighting is allowed to pass through at grazing angles like you see here. To fix this, you'll need to use a different lighting model;

 //Change this
 #pragma surface surf Standard
 
 //To this
 #pragma surface surf Lambert
 
 ...
 
 //Also need to use a different output struct;
 void surf (Input IN, inout SurfaceOutput o)
 {
