Use Reflection Map with Vertex Colors?

Question

Hi, I am a new Unity user. I have a model that I baked Ambient Occlusion to Vertex Colors from within Blender. Since my model is supposed to be sort of plastic, I have created a cube map (in Unity). The problem is, I cannot mix a Reflection shader with the "Mobile>Vertex Colored" shader. I heard that ShaderLab is the way to go, so I tried it, but I can never mix the two! Des anyone know how to mix the two shaders so I can use Vertex Colors and reflection map?

GREAT THANKS in advance. ;)

Here's a vertex-lit shader from Unity docs. Note that "primary" is the vertex color.

 Shader "VertexLit" {
     Properties {
         _Color ("Main Color", Color) = (1,1,1,0)
         _SpecColor ("Spec Color", Color) = (1,1,1,1)
         _Emission ("Emmisive Color", Color) = (0,0,0,0)
         _Shininess ("Shininess", Range (0.01, 1)) = 0.7
         _MainTex ("Base (RGB)", 2D) = "white" {}
     }
     SubShader {
         Pass {
             Material {
                 Diffuse [_Color]
                 Ambient [_Color]
                 Shininess [_Shininess]
                 Specular [_SpecColor]
                 Emission [_Emission]
             }
             Lighting On
             SeparateSpecular On
             SetTexture [_MainTex] {
                 Combine texture * primary DOUBLE, texture * primary
             }
         }
     }
 }

And here's code from Unity docs for adding a reflection map using ShaderLab:

 //in properties
 _Reflections ("Base (RGB) Gloss (A)", Cube) = "skybox" { TexGen CubeReflect }
 
 //in pass
 SetTexture [_Reflections] {
                 combine texture
                 Matrix [_Reflection]
             }

You should be able to strip out the stuff you don't want from the shader (spec, ambient, emission, etc).

Please check docs before asking questions. Hope this helps.
