Custom Standard shader isn't receiving shadows.

Hi folks,

Sorry if this gets posted all the time, but I couldn't find an answer specific to this.

I've created a quick shader based on the Standard Specular as I needed 2 sided rendering, but it's not receiving shadows for some reason. Any ideas what I'm missing?

Code (csharp):

1. Shader "Standard (2 Sided)" {
2.     Properties {
3.         _Color ("Color", Color) = (1,1,1,1)
4.         _MainTex ("Albedo (RGBA)", 2D) = "white" {}
5.         _Glossiness ("Smoothness", Range(0,1)) = 0.5
6.         _Specular ("Specular Color", Color) = (0,0,0)
7.         _Cutoff ("Cutoff", Range(0,1)) = 0.5
8.     }
9.  
10.     SubShader {
11.         Tags {"Queue"="Transparent" "IgnoreProjector"="True" "RenderType"="TransparentCutout"}
12.         LOD 200
13.         Blend SrcAlpha OneMinusSrcAlpha
14.         Cull Off
15.        
16.        
17.         CGPROGRAM
18.         #pragma surface surf StandardSpecular alpha:fade fullforwardshadows
19.         #pragma target 3.0
20.  
21.         sampler2D _MainTex;
22.  
23.         struct Input {
24.             float2 uv_MainTex;
25.         };
26.  
27.         half _Glossiness;
28.         fixed3 _Specular;
29.         float _Cutoff;
30.         fixed4 _Color;
31.  
32.         void surf (Input IN, inout SurfaceOutputStandardSpecular o) {
33.             // Albedo comes from a texture tinted by color
34.             fixed4 c = tex2D (_MainTex, IN.uv_MainTex);
35.             o.Albedo = c.rgb;
36.             // Metallic and smoothness come from slider variables
37.            
38.            
39.             if (c.a > _Cutoff) {
40.                    o.Alpha = c.a;
41.                 o.Specular = _Specular;
42.                 o.Smoothness = _Glossiness;
43.                    }
44.              else
45.              {
46.                    o.Alpha = 0;
47.                    }
48.         }
49.         ENDCG
50.     }
51.     FallBack "Standard"
52. }

Thanks!

 

In Unity shaders using the transparent queue don't receive shadows.
