Vertex Color Shader Turns Transparent Help

I am having trouble creating my shader to vertex paint this tree properly. I have vertex painted this tree in 3DS MAX with two colors using Vertex Paint map and then exported .FBX

I am a novice at writing shaders but after some time I have gotten it so the colors show, except they are florescent transparent when viewed in game.

Here is my simple shader:

Code (csharp):

1.  
2.  
3. Shader "Vertex Shader" {
4.    Properties{
5.      _MainTex("Base (RGB)", 2D) = "white" {}
6.    }
7.      SubShader{
8.      Tags{ "Queue" = "Geometry" "IgnoreProjector" = "False" "RenderType" = "Opaque" }
9.      LOD 200
10.  
11.      CGPROGRAM
12. #pragma surface surf Lambert alpha
13.  
14.  
15.    struct Input {
16.      
17.      float4 color: Color;
18.    };
19.  
20.    void surf(Input IN, inout SurfaceOutput o) {
21.      
22.      o.Albedo = IN.color.rgb;
23.      o.Alpha = IN.color.a;
24.    }
25.    ENDCG
26.    }
27.      FallBack "Diffuse"
28. }
29.  
30.  

 

If you don't want it to be transparent, remove the word "alpha" from line 12

 

Or set it to 1 to be sure there is no residual data
