Prioritizing Visibility of Meshes

So after a little bit of reading on the subject of how to control the order of rendering I determined that using Custom Shaders was the way to go. Because my particular materials for my project are texture mapped with colored images, I don't have to worry about lighting therefore I was able to use the most basic Vertex and fragment shader described here: http://docs.unity3d.com/Manual/SL-VertexFragmentShaderExamples.html.

Then I used the Tags section to specify the Render Queue by setting the "Queue" tag to a value of "Geometry+n" where n grew with the precedence . NExt you must set the ZTest Always I then went to the material I was applying to the mesh and set the Shader to be the Custom Shader associated with the priority associated with.

The basic idea is setting that all the meshes Always show up (that's the ZTest part) but then you also manipulate the order in which things are rendered to make it customizable. I used this method and it worked ideally for my reasons.

NOTE! This will cause weird results if you have many "lower priority" hills that cover up your "higher priority" meshes.

An example of the Shader I used is:

 Shader "Custom/New Shader"{
     Properties {
         _MainTex ("Base (RGB)" , 2D) = "white" {}
     }
     SubShader{
         Tags{"Queue" = "Geometry+1"}
         Pass{
             ZTest Always
             CGPROGRAM
             
             #pragma vertex vert_img
             #pragma fragment frag
             
             #include "UnityCG.cginc"
             
             uniform sampler2D _MainTex;
             
             float4 frag(v2f_img i): COLOR {
                 return tex2D(_MainTex, i.uv);
             }
             
             ENDCG
         }
     
     }
 }
