Fresnel shader with Vertex color

Questions & Answers
1

I’ve found nice Fresnel shader here. It works perfectly, but I want to use it as particle shader, so I should somehow make vertex color (it is affected by Shuriken) affect rim color. I’ve crawled through built-in particle shaders code, but didn’t make it work.

Here is the code of fresnel shader

 Shader "Custom/TransparentFresnel"
 {
     Properties
     {
         _MainTex("Texture", 2D) = "white" {}
         _InnerColor("Inner Color", Color) = (1.0, 1.0, 1.0, 1.0)
         _RimColor("Rim Color", Color) = (0.26,0.19,0.16,0.0)
         _RimPower("Rim Power", Range(0.5,8.0)) = 3.0
     }
         SubShader
     {
         Tags{ "Queue" = "Transparent" }
 
         Cull Back
         Blend One One
         ZWrite Off
 
         CGPROGRAM
 #pragma surface surf Lambert
 
     struct Input
     {
         float2 uv_MainTex;
         float3 viewDir;
     };
 
     sampler2D _MainTex;
     float4 _InnerColor;
     float4 _RimColor;
     float _RimPower;
 
     void surf(Input IN, inout SurfaceOutput o)
     {
         o.Albedo = tex2D(_MainTex, IN.uv_MainTex).rgba * _InnerColor;
         half rim = 1.0 - saturate(dot(normalize(IN.viewDir), o.Normal));
         o.Emission = _RimColor.rgba * pow(rim, _RimPower);
     }
     ENDCG
     }
         Fallback "Diffuse"
 }

Solved myself

Shader "Custom/TransparentFresnel"
  {
      Properties
      {
          _MainTex("Texture", 2D) = "white" {}
          _InnerColor("Inner Color", Color) = (1.0, 1.0, 1.0, 1.0)
          _RimColor("Rim Color", Color) = (0.26,0.19,0.16,0.0)
          _RimPower("Rim Power", Range(0.5,8.0)) = 3.0
      }
          SubShader
      {
          Tags{ "Queue" = "Transparent" }
  
          Cull Back
          Blend One One
          ZWrite Off
  
          CGPROGRAM
  #pragma surface surf Lambert
  
      struct Input
      {
          float2 uv_MainTex;
          float3 viewDir;
          float4 color: Color;
      };
  
      sampler2D _MainTex;
      float4 _InnerColor;
      float4 _RimColor;
      float _RimPower;
  
      void surf(Input IN, inout SurfaceOutput o)
      {
      	  float4 fader = (IN.color.a, IN.color.a, IN.color.a);	
          o.Albedo = tex2D(_MainTex, IN.uv_MainTex).rgba * _InnerColor;
          half rim = 1.0 - saturate(dot(normalize(IN.viewDir), o.Normal));
          o.Emission = _RimColor.rgba * pow(rim, _RimPower)*IN.color.rgb*fader;
      }
      ENDCG
      }
          Fallback "Diffuse"
  }
