Prepass Queue and Custom lighting

Hey!

I want to have a texture for the specular color, so I made a shader for that, but I'm having some issues...
It works fine as long as I'm in the transparent Queue, as soon as I switch to Geometry queue the lighting becomes all wrong on the model...

here's the shader.

Code (CSharp):

1. Shader "Characters/DNSE" {
2.     Properties {
3.         _MainTex ("Base (RGB)", 2D) = "white" {}
4.         _SpecTex("Specular Texture",2D) = "black" {}
5.         _Shininess("Glossiness",Range(0,2)) = 1.0
6.         _Bump("NormalMap",2D) = "bump" {}
7.     }
8.     SubShader {
9.         Tags { "Queue" = "Geometry" "RenderType"="Opaque" }
10.         LOD 200
11.        
12.         CGPROGRAM
13.         #pragma surface surf Characters nolightmap nodirlightmap
14.  
15.         sampler2D _MainTex;
16.         sampler2D _Bump;
17.         sampler2D _SpecTex;
18.        
19.         float _Shininess;
20.        
21.         struct CustomSurfaceOutput
22.         {
23.             fixed3 Albedo;
24.             fixed3 Normal;
25.             fixed3 Emission;
26.             fixed3 GlossColor;
27.             fixed Specular;
28.             fixed Alpha;
29.         };
30.  
31.         struct Input {
32.             float2 uv_MainTex;
33.         };
34.        
35.        
36.         inline fixed4 LightingCharacters ( CustomSurfaceOutput s, fixed3 lightDir, fixed3 viewDir, fixed atten){
37.  
38.             half3 h = normalize (lightDir + viewDir);
39.  
40.             fixed NdotL = max (0, dot (s.Normal, lightDir) * 0.5 + 0.5 );
41.             fixed NdotH = max (0, dot (s.Normal, h));
42.  
43.             fixed3 spec = pow (NdotH, _Shininess*128.0);
44.             fixed3 specCol = spec * s.GlossColor.rgb;
45.            
46.             fixed4 c;
47.            
48.             c.rgb = (s.Albedo * _LightColor0.rgb * NdotL + _LightColor0.rgb * specCol) * (atten * 2.0);
49.             c.a = s.Alpha + _LightColor0.a * spec * atten;
50.            
51.             return c;
52.  
53.         }
54.        
55.         inline fixed4 LightingCharacters_PrePass (CustomSurfaceOutput s, half4 light)
56.         {
57.             fixed3 spec = light.a * s.GlossColor;
58.          
59.                fixed4 c;
60.             c.rgb = s.Albedo * light.rgb + light.rgb * spec;
61.             c.a = s.Alpha + spec;
62.             return c;
63.         }
64.  
65.         void surf (Input IN, inout CustomSurfaceOutput o) {
66.             fixed3 tex = tex2D (_MainTex, IN.uv_MainTex);
67.             fixed3 spec = tex2D (_SpecTex, IN.uv_MainTex);
68.             fixed3 bump = UnpackNormal(tex2D(_Bump,IN.uv_MainTex));
69.            
70.             o.Albedo = tex;
71.             o.Normal = bump;
72.             o.GlossColor = spec;
73.  
74.         }
75.         ENDCG
76.     }
77.     FallBack "Diffuse"
78. }
79.  

the forward pass works fine, only the deferred pass gives me this problem...

Thanks!

 

nice question, i want to see a specular color shader, geometry shader is DX11 only ??!? do you have a geom shader there? i see that the CG isnt specified which version i.e. dx9 / dx11 , the version config line is missing. i dunno i am abit noob.

 

no, that's not a geomerty shader, just a regular sufrace shader with custom lighting model.
