Surface Shader cube normal

Hi,

I want ton convert the unity toonshader to a surface shader. There is something I don't know how to convert. In the vertex program they do that:

Code (csharp):

1.            
2. v2f vert (appdata v){
3. v2f o;
4. o.pos = mul (UNITY_MATRIX_MVP, v.vertex);
5. o.texcoord = TRANSFORM_TEX(v.texcoord, _MainTex);
6. o.cubenormal = mul (UNITY_MATRIX_MV, half4(v.normal,0));
7. return o;
8. }
9.  

How does

Code (csharp):

1.  o.cubenormal = mul (UNITY_MATRIX_MV, half4(v.normal,0));

translates in surface shader?

Thanks!

 

Nevermind, I found it!! it was the same, only the vertex program wasn't declared the same way!

gives somthing like this:

Code (csharp):

1.  
2.         void vert (inout appdata_full v, out Input o) {
3.             UNITY_INITIALIZE_OUTPUT(Input,o);
4.             o.cubeNorm = mul (UNITY_MATRIX_MV, half4(v.normal,0));
5.  
6.     }
7.  
8.
