Custom Surface Shader not received shadow

Hi.
I have this code.

Code (CSharp):

1. Shader "Custom/shProbe01" {
2.     Properties {    
3.         _Color ("Color", Color) = (1,1,1,1)
4.         _AmbientColor ("Ambient Color", Color) = (0,0,0,0)
5.         _SpecCC ("Specular Color", Color) = (1,1,1,1)
6.         _TextureCP ("Composicion Textura", 2D) = "white"{}            
7.         //_TextureNP ("NormalMap", 2D) = "white"{}            
8.         _SpecPower ("Specular Power", Range(0,128)) = 30
9.         _SpecIntensity ("Specular Intensity", Range(0,10)) = 5
10.         _RepeatSpecText ("Repeat Specular Tex", Range(0,50)) = 20
11.         _RepeatCCText ("Repeat Color Tex", Range(0,50)) = 13
12.         _NumberAct ("Number Mark", Range(0,1)) = 0
13.     }
14.  
15.     SubShader {
16.         Tags {
17.             "RenderType"="Opaque"
18.          }
19.         CGPROGRAM
20.      
21.         #pragma surface surf Phong
22.         #pragma target 3.0

28.         sampler2D _TextureCP;
29.         //sampler2D _TextureNP;
30.         fixed _SpecPower;
31.         fixed _SpecIntensity;
32.         fixed _RepeatSpecText;
33.         fixed _RepeatCCText;
34.         fixed _NumberAct;
35.      
36.         struct Input {
37.             float4 color : COLOR;
38.             float2 uv_TextureCP;
39.             float2 uv_TextureNP;
40.         };
41.  
42.         inline fixed4 LightingPhong ( SurfaceOutput s, fixed3 lightDir, half3 viewDir, fixed atten){

45.             fixed3 reflectionVector = normalize( 2.0*s.Normal*dotDiff - lightDir );
46.          
47.             float spec = pow ( max ( 0, dot(reflectionVector, viewDir)), _SpecPower);
48.             fixed3 finalSpec = clamp(0.0,1.0,s.Specular * _SpecCC * spec);
49.          
50.             fixed4 c;
51.             c.rgb =  (_AmbientColor*s.Albedo) + (_Color * s.Albedo * _LightColor0.rgb * dotDiff * atten * 2) + (_LightColor0.rgb * finalSpec * atten * 2);
52.             c.a = 1.0;
53.             return c;
54.          
55.         }
56.      
57.         void surf (Input IN, inout SurfaceOutput o) {
58.             fixed4 finalCC;
59.             fixed4 finalSP;
60.             fixed4 finalMK;
61.          
62.             finalSP = tex2D(_TextureCP, IN.uv_TextureCP*_RepeatSpecText);
63.             finalCC = tex2D(_TextureCP, IN.uv_TextureCP*_RepeatCCText);
64.             finalMK = tex2D(_TextureCP, IN.uv_TextureCP);
65.  
66.             //o.Normal = UnpackNormal(tex2D (_TextureNP, IN.uv_TextureNP));
67.             if (_NumberAct > 0.0)
68.                 o.Albedo = (1.0-finalMK.g)*lerp(finalCC.b, float4(0.594,0.594,0.594,0.0), 0.5);
69.             else
70.                 o.Albedo = (1.0-finalMK.a)*lerp(finalCC.b, float4(0.594,0.594,0.594,0.0), 0.5);
71.              
72.             o.Specular = _SpecIntensity*finalSP.r;
73.              
74.             o.Alpha = 1.0;
75.         }
76.         ENDCG
77.     }
78.     FallBack "Diffuse"
79. }

But the objects that I applied this shader not received shadow. See image file.

I need to activate something?. Thx

 

Hi. thanks for your reply.

1. Add fullforwardshadows... done!.

#pragma surface surf Phong fullforwardshadows

2. Checking MeshRenderer have receive shadow... done!.

But the mesh still doesnt receive shadow . Even if I use directional light.

Maybe some setting in Unity that is not activated?
